DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk storage system for storing information in an optical disk medium cartridge using an optical disk drive and an optical disk library device, and a computer-readable recording medium recording a copy processing program therefor. The present invention relates to an optical storage system functioning as a duplicator for making a large number of copies of an original medium cartridge and a computer-readable recording medium recording a copy processing program.

2. Description of the Related Art In recent years, an optical disk has been recently developed because of a large capacity exceeding 200 MB and a merit of a cartridge which enables movement of a medium between different optical disk drives.
It is exerting its power under the environment of dows and the environment of using large-scale software. Especially in recent years,
With the advent of the 3.5-inch optical disk drive, cost reduction and improvement in access speed have been achieved, and performance comparable to that of a standard hard disk drive (HHD) one generation ago can be obtained.

However, since the storage capacity of an optical disk cartridge alone is limited, a plurality of optical disk cartridges are stored in the apparatus, and a robot hand picks up the necessary optical disk cartridge, loads the optical disk cartridge into an optical disk drive, and performs recording and reproduction. Type optical disk library devices have been proposed. In recent years, there has been a copy job of creating a large number of copies of an optical disk cartridge using such an optical disk library device. For example, when confidential data that cannot be stored online is distributed from a head office to a plurality of branches, a large amount of confidential data is copied using a library device.

For copy work using such a library device, an optical disk drive device (hereinafter referred to as an “MO drive device”) and an optical disk library device (hereinafter referred to as “MO drive device”) are connected to a personal computer functioning as a host via a device bus such as SCSI. MO library device ”). Then, a copy source optical disk cartridge (hereinafter referred to as "MO cartridge") is inserted into the MO drive device, a plurality of copy destination MO cartridges are inserted into the MO library device, and continuous copying from the copy source cartridge to the copy destination cartridge is performed. I'm trying to do it.

[0005]

However, for a large number of copies, a large number of M's can be read by one personal computer.
When controlling the O drive device and MO library device,
It is difficult to understand the correspondence between the device displayed on the screen and the actual device. For this reason, even if the user recognizes the copy source device and the copy destination device on the screen, the copy source M
Insert the O cartridge and copy the MO
There was a problem that it was very difficult to understand whether a cartridge should be inserted.

For this reason, the user checks in advance the ID of the SCSI bus to which each device is connected, and compares this ID with the environment setting file of the copy software so that the device on the screen and the actual device can be compared. I had to recognize the correspondence myself. Conventional MO drive device and MO library device are 230 MB, 540
It supports three types of MO cartridges, MB and 640 MB. However, when copying from the MO cartridge of the MO drive device to the MO cartridge stored in the MO library device in the conventional system, an MO cartridge having the same capacity as the copy source MO cartridge must be inserted into the copy destination MO library device. And the inconvenience of having to unify the capacity.

[0007] The capacity mismatch at the copy destination is determined only when the copy process is repeated from the copy source MO cartridge to the copy destination MO cartridge in sector units, and it is found that copying is possible beyond the last sector. It is determined that there is. For this reason, there is a problem that it takes a very long time until an error due to a difference in cartridge capacity is found. Furthermore, since the capacity of the copy source and the capacity of the copy destination must be the same, there is a problem that an error occurs even if the capacity of the copy destination is large.

Furthermore, in the conventional system, the copy source MO
Regardless of the recorded contents of the cartridge, the copying process is performed for all the sectors, and there is a problem that it takes time because the copying process is performed for the empty sector where no data is recorded. Further, even when the copy source data is small, it has not been possible to copy a plurality of copy source cartridges to one copy destination cartridge.

Further, the conventional system uses a plurality of Ms of the MO library device from the MO cartridge of the MO drive device.
When copying is performed to an O-cartridge, if there are a plurality of copy sources, copying must be performed one by one, and there is a problem that it takes time for processing. Furthermore, in the conventional system,
The combination of the copy source and the copy destination is determined according to the MO drive device and the MO library device actually connected to the personal computer. To change the combination of the copy source and the copy destination, The connection configuration had to be changed as well.

The present invention has been made in view of such a conventional problem, and has a degree of freedom in which copy processing can be efficiently performed by an optimum system form without being restricted by a difference in medium capacity or a mounting state of a device. It is an object of the present invention to provide an optical storage system having a high storage capacity and a computer-readable recording medium in which a copy processing program thereof is recorded.

[0011]

FIG. 1 is a diagram illustrating the principle of the present invention. The optical storage system of the present invention includes one or a plurality of MO drive devices (optical drive devices) 12 for processing a single medium, a medium storage unit storing a plurality of media,
An optical drive unit for optically accessing the medium,
And an accessor for transporting a medium between the medium storage unit and the optical drive unit.
A library device (optical library device).

The MO drive device 12 and the MO library device 16 are connected to one or more device buses such as SCSI drawn from the host device 10. The host device 10 is provided with a copy processing unit 70, which copies the storage contents of the medium of the copy source device set in advance to the medium of the copy destination device set in advance. Further, a confirmation processing unit 76 is provided in the host device 10, and device graphics of a plurality of devices to be accessed by the copy processing unit 70 are arranged and displayed on a screen as shown in FIG. When the user operates the check area 165 provided on the screen on the screen,
A confirmation command is sent to the corresponding device to cause the operator to perform an output operation for confirming the device.

The confirmation processing unit 76 drives the indicator lamp and the sound device of the target device to make the operator confirm the corresponding device. For the MO library device 16, the operator can also drive the accessor to confirm the corresponding device to the operator. As described above, when the check area for device confirmation provided in the device graphics on the screen is clicked with the mouse, the actual MO is clicked.
The library or the MO drive device responds by blinking the indicator lamp or the like, and the user does not need to check the SCSI bus ID of the device and refer to the environment setting file and the like, thereby improving operability.

The host device is provided with a system configuration control section 72 and a copy information setting section 74 in addition to the copy processing section 70. The system configuration control unit 72 operates the connection instruction area for connecting to the system provided in the device graphics on the screen and the disconnection instruction area for disconnecting from the system, and performs system connection of an arbitrary storage device as necessary. And system disconnection to determine the system configuration.

The copy information setting section 74 sets copy information necessary for access to the copy processing section 70 for the system configuration determined by the system configuration control section 72. The copy information setting unit 74 automatically determines a copy source and a copy destination based on the system configuration determined by the system configuration control unit 72 and sets copy information. The automatic setting of the copy information is as follows, for example.

Mode 1: One MO drive device 12 and one or more MO library devices 16 for one bus system
Is connected to the MO drive device 1
2 is automatically set as a copy source and all of the MO library devices 16 are automatically set as copy destinations. Mode 2: In the case of a system configuration in which one MO drive device 12 is used and one or more MO library devices 16 are connected to the same bus system, the MO drive device 12 is automatically set as a copy source and all the MO library devices 16 are used. Automatically set the copy destination.

Mode 3: One MO drive device 12 is provided for each of the plurality of bus systems, and the MO library device 1 is provided for each bus system.
In the case of a system configuration in which one or more devices 6 are connected, the MO drive device 12 is automatically set as a copy source for each bus system, and all the MO library devices 16 are automatically set as copy destinations.

Mode 4: Multiple MO library devices 16
In the case of a system configuration in which only a different bus system is connected, the MO library device 16 of a predetermined specific bus is automatically set as a copy source, and all the other MO library devices 16 are automatically set as copy destinations. Here, in the automatic setting of the copy source and the copy destination, the copy information setting unit 7
When the MO library device 16 is set as the copy destination device, all media stored in the MO library device 16 are set as copy destination media. As described above, by automatically determining the copy source and the copy destination based on the system configuration mode, it is possible to provide an optimal copy processing system mode without requiring user's determination.

On the other hand, in another embodiment of the copy information setting section 74, a copy source apparatus, a copy source apparatus,
The user can arbitrarily set the copy destination device as needed. In the setting in the user mode, the copy information setting section 74 sets the specific M in advance when the copy source apparatus is not specified using the copy information setting screen.
The O drive device 12 or the MO library device 16 is automatically set as the copy source device. If no copy destination device is specified using the copy information setting screen, all MO library devices 16 except the copy source device are automatically set as copy destination devices.

Further, the copy information setting section 74 uses the copy information setting screen to copy the number of mediums of the copy source, the number of mediums of the copy destination, and the number of copies within the group or beyond the group for the device group divided for each bus system. Copying can be set arbitrarily as needed. If the copy destination is the MO library device 16 and the number of copy destination media has not been set, the copy information setting unit 74 sets the MO
All media in the library device 16 are automatically set as copy destination media.

By setting copy information by the user using such a screen, an arbitrary copy mode can be set as needed, and copy processing with extremely high flexibility can be easily realized. When the copy source medium includes a medium having a different capacity from the copy destination medium, the copy processing unit 70 copies the data to a copy destination medium having the same capacity. Specifically, the copy processing unit 70 repeats the copying process from the copy source medium to the copy destination medium in sector units, and after completing the last sector of the copy source medium, performs a dummy copy for one more sector, and performs the dummy copy. If an error occurs, it is determined that the capacities are the same, and the copying process is terminated normally. If the dummy copying is normally performed, it is determined that the capacities are different, error information is recorded, and the process is terminated.

Therefore, even when MO cartridges having different capacities are mixed in the MO library apparatus 16 at the copy destination, copying can be performed if an MO cartridge having the same capacity as the copy source is inserted, and the cartridge capacity is unified. Because it is not necessary to do it, it is convenient. Copy processing unit 7
0 is used when copying from the copy source device to the copy destination device.
The capacity of the copy destination medium is read, and only the copy destination medium having the same capacity is copied. By reading the capacity of the MO cartridge at the copy destination before starting the copy processing in this way, an error can be immediately recognized without waiting for the end of the copy processing, and the processing time can be reduced.

When the copy destination medium includes a medium having a capacity different from that of the copy source medium, the copy processing section 70 copies the data to a copy destination medium having a capacity equal to or larger than the copy source medium. Specifically, the copy processing unit 70 repeats the copying process from the copy source medium to the copy destination medium in sector units, and if an error occurs until the last sector of the copy source medium, determines that the capacity is insufficient and records error information. If the copying has been completed up to the last sector of the copy source medium, it is determined that the capacity is equal to or larger than the copy source capacity, and the copy processing is terminated normally.

For this reason, it is possible to perform a copy process such as uniforming the capacity of the copy destination medium to a medium having a capacity larger than the capacity of the copy source medium. The copy processing unit 70 reads and recognizes the data recording area of the copy source medium in advance, and copies only the recognized recording area to the copy destination medium. By copying only the recording area of the copy source, the processing time can be reduced.

The copy processing section 70 reads the data recording areas of the plurality of copy source media in advance to recognize the total amount of data of the copy source, and reads the copy destination medium in advance to recognize the capacity, and recognizes the capacity of the copy destination medium. Is greater than or equal to the total data amount of the copy source, a plurality of copy source media are collectively copied to one copy destination medium. Therefore, a plurality of copy source media having a small medium capacity can be collectively copied to a copy destination medium having a large capacity, and the number of copied copy media can be reduced.

The copy processing unit 70 is provided in the library device 16
In the inter-copying process, a plurality of copy source media are copied as one group to a plurality of groups of copy destination media. In this case, in addition to the copy processing between different library devices 16, a plurality of copy source media can be copied as a group to a plurality of groups of copy destination media for a plurality of media in the same MO library device 16.

The MO library device 16 used in the present invention has two MO drives. When the optical library device 16 is used as a copy destination, the copy processing unit 70 controls the MO drive device 12 of the copy source. The copy data read from the medium is stored in the MO library 16
The data is sequentially transferred to one MO drive and written to the copy destination medium in parallel.

Further, the medium used in the present invention is, for example, 2
MO cartridges of 30 MB, 540 MB and 640 MB. Further, the present invention provides one or more MO drive devices 12 for processing a single replaceable medium, a medium storage unit storing a plurality of replaceable media, an optical drive unit for optically accessing the medium, and a medium. One or more MO library devices comprising an accessor for transporting a medium between a storage unit and an optical drive unit,
And the MO drive device 1 pulled out from the host device 10
The present invention provides a computer-readable recording medium recording a copy processing program used in an optical storage system including one or a plurality of device buses 14 for connecting the MO library device 2 and the MO library device 16 as a storage device.

The computer-readable recording medium on which the copy processing program is recorded is installed in the higher-level device 10, and replaces the storage contents of the preset copy source storage device with the preset copy destination storage device. A copy processing unit for copying to a medium and device graphics of a plurality of storage devices which are also installed in the host device 10 and are accessed by the copy processing unit are arranged and displayed on a screen, and a check area provided in each device graphics When an instruction operation is performed on the screen, a confirmation processing unit is transmitted to the corresponding storage device to cause the operator to perform an output operation for confirming the device. The copy control program for the storage medium is installed in the host device 10 as an OS or an application.

When only the MO library devices 16-1 to 16-8 are connected without connecting the drive devices 12-1 to 12-4, copy processing between the library devices is performed. Copy processing between MO library apparatuses is divided into copy processing that exceeds the bus system and copy processing for each bus system. Also in this case, the MO library device serving as a copy source is called a copy master.

The copy form by the externally connected MO drive device and MO library device depends on the system form set in software by the system configuration control section 72 within the range of the mounting state of the device, and this point will be described later. It will be clarified in detail in the description. FIG. 9 shows the host computer 1 of FIG.
It is a generic flowchart of the copy processing by the function on the 0 side. In the copy process, first, in step S
In step S1, a system configuration setting process is performed.
In step 2, copy information setting processing is performed. Based on the system configuration and the setting of the copy information, a copy mode for performing what kind of copy processing from which copy source to which copy destination is determined.

If the copy mode has been determined, a copy start operation is waited for in step S3, and if the copy start operation is performed, the process proceeds to step S4, in which the copy source cartridge according to the copy mode already determined is changed to the copy destination cartridge. Is performed. Then, step S5
Check if there is a verify setting. Step S2
If the verify setting has been performed in the copy information setting process, the verifying process is performed for all of the copy destination media by data collation with the copy source media in step S6, and a series of copy processes ends. Of course, if there is no verify setting, the copy processing ends immediately.

FIG. 10 is an explanatory diagram of a series of channel command words CCW issued from the host computer to the external system components in the copy processing of step S4 in FIG. First, the copying process from the copy source medium to the copy destination medium is basically performed in sector units formatted in the medium cartridge. 230 MB cartridge media supported by the system of the present invention, 5
The number of sectors of the 40 MB cartridge medium and the 640 MB cartridge medium is as follows: 230 MB is a hexadecimal 6CF75 sector, 540 MB is a hexadecimal FE45C sector, 640
The MB is 4BC50 sectors in hexadecimal.

The sector capacity is 230 MB and 540 MB.
Is 512 bytes and 640 MB is 2048 bytes. Therefore, the copy process from the copy source cartridge to the copy destination cartridge is performed by issuing the channel command words CCW1 to CCWn in sector units from the first sector to the last sector of the copy source medium. First, the channel command word CCW1 of the first sector includes a move command 88, a copy source read command 90-1, and a copy destination first command.
It is composed of a command chain of a write command 92-1 and a copy destination second write command 94-1. The move command 88 is a first MO having a cartridge housed in a slot of the MO library apparatus as a copy destination.
This is a command for transporting and inserting into the drive and the second MO drive.

This move command 88 is shown in FIG.
It has a command format like This command format is a move command code 98, an HHDD which is a device address 100, a source address 10
FROM-ADDR to be 2 and destination address 10
4 TO-ADDR. The HHDD serving as the device address 100 corresponds to the card slots 82-1 to 82- provided in the card interface processing unit 80 in FIG.
4 and a SCSI device adapter model number DD defined by a bus ID assigned to each of the SCSI buses 14-1 to 14-4.

This device address HHDD is as shown in FIGS. 12 and 13 in the case of the system configuration of FIG. First, group numbers G0 to G3 are assigned to each of the four SCSI buses 14-1 to 14-4. Here, taking the group number G0 of the SCSI bus 14-1 in FIG. 11 as an example, the group number G0 includes the MO drive device having the device number # 0 and the device number # 0, # as shown in the device name. Two MO library devices having a "1" are included.

Each of the MO library devices has an accessor, a first MO drive, and a second MO drive. Therefore, the device address HHDD of the MO drive device of the group number G0 is “0001”. For the MO library device with device number # 0,
The accessor is “0002” and the first MO drive is “00”.
03 "and the second MO drive is" 0004 ".
For the MO library device of machine number # 1, the accessor is “0005” and the first MO drive is “000”.
6 "and the second MO drive are" 0007 ".

Referring again to the command format of the move command shown in FIG.
Element numbers physically assigned to the slots of the MO library apparatus and the two MO drives are used for the source address 102 and the destination address 104 provided after 0. FIG. 11B shows the source address 1
02 and the MO drive in the library apparatus for setting the destination address 104 and the correspondence between element numbers and slot numbers.

That is, the element number “00” is assigned to the first MO drive, the element number “01” is assigned to the second MO drive, and the element number “02” is assigned to 35 slots 01 to 35 which can store the remaining cartridges. "To" 37 "are assigned. Figure 1 again
Referring to 0, a copy source read command 90-1 is issued following the move command 88 of the first sector. This read command has a command code "REA" as the command code 106 as shown in the command format of FIG.
D ”,“ HHDD ”as device address 108
And a sector number 110. By issuing the read command to the copy source apparatus, the read processing of the sector data corresponding to the sector number 110 is performed, and the read data is transferred to the host computer.

Referring again to FIG. 10, following the copy source read command 90-1 of the first sector, the copy destination first write command 92-1 and the copy destination second write command 9
4-2 is arranged. As is apparent from the system configuration shown in FIG. 8, the copy destination MO library apparatus of the present invention has the first and second MO drives built in, and thus is obtained by issuing the copy source read command 90-1. The copy source sector data once transferred to the transfer buffer memory 86
After that, the data is sent to the first MO drive of the copy destination MO library device together with the copy destination first write command 92-1 to perform the sector data write operation.

Subsequently, the same read data is sent to the second MO drive of the copy destination MO library device by the copy destination second write command 94-1 to perform a parallel write process of writing sector data. FIG. 14B shows a command format of a write command used in FIG.
"WRITE" as the command format 112,
Following “HHDD” as the device address 114 and the sector number 116, sector data 118 obtained by the read command in FIG. 14A is added.

The channel command words CCW2 to CCWn from the second sector to the last sector include a copy source read command 90-2 to 90-n, a copy destination first write command 92-2 to 92-n, and a copy destination second command. This is a repetition of the write commands 94-2 to 94-n. When the copy process of the last sector of the copy source is completed by issuing the channel command word CCWn of the last sector, the channel command word CC for writing the dummy sector at the end
Issue Wn + 1. The channel command word CCWn + 1 for writing the dummy sector is a processing command for confirming that the medium capacity of the copy destination is larger than the medium capacity of the copy source.

That is, the copy destination first write command 90-
By issuing (n + 1), the first MO of the MO library device
The drive is instructed to write a dummy sector, and if the dummy sector is successfully written, it is understood that the medium capacity of the copy destination medium is larger than the copy source. If writing of the dummy sector fails, it is understood that the capacity of the copy destination medium is the same as the capacity of the copy source medium.

Next copy destination second write command 92-
Also in (n + 1), a confirmation process is performed on the medium capacity of the second MO drive of the MO library device by writing the same dummy sector. Finally, a move command 96 is issued, and the first MO drive and the second
Remove the cartridge after the copy process from the MO drive and return it to the original slot in order.

Note that the writing of the dummy sector performed after the last sector is used when the medium capacity is not checked before the copy processing. If the medium capacity check is performed before the copy processing, the dummy sector is written. Writing is unnecessary, and the move command 9 is added at the end of the last sector.
6 may be arranged. 3. System Configuration Control and Copy Information (1) Device Configuration Control FIG. 15 is a device configuration screen displayed on a display 78 used for configuration control of the system configuration control 72 provided in the host computer 10 of FIG.

A check box 165 is provided at the upper right of the upper portion of the device graphics 16-1 for activating a process for confirming the correspondence between the device on the screen and the actual device. Further, a copy execution key 174 for executing the copy processing according to the present invention is arranged at the lower center of the screen. FIG. 16 is a flowchart of a device confirmation process started by clicking a check box 165 provided in each device graphics on the device configuration screen of FIG. 15 with a mouse, that is, a device confirmation process. First, step S1
Then, the check box 165 of the device to be confirmed in the apparatus configuration screen 16-2 in FIG. 15 is clicked with the mouse cursor.

In response to the mouse click, step S2
Investigate the clicked position on the screen and determine the corresponding device. Specifically, the corresponding device address HHDD is determined. Next, in step S3, it is checked whether the device requested to be confirmed is mounted on the system. The device configuration screen 162 in FIG. 15 shows a case where all the device graphics are displayed in a black frame, and therefore all are implemented in the maximum configuration as shown in FIG. If it is not mounted, the black frame of each device graphics disappears, indicating that it is not mounted.

When it is recognized in step S3 that the device to be confirmed is mounted on the system, a position confirmation command is issued to the device in step S4, and, for example, an online indicator light as shown in FIG. 15,
A position confirmation operation by blinking of 24 or the like is performed. As the position confirmation command issued in step S4, if the target device is an MO library device, a move command shown in FIG. Flashing drive.

If the target device is an MO drive device, a read command shown in FIG.
What is necessary is just to blink the online indicator light 15 shown in FIG. Therefore, when the user sets the copy source cartridge and the copy destination cartridge on the device configuration screen 162 in FIG. 15 prior to the copy processing, the check box 165 provided in the device graphics of each device of the copy source and the copy destination. By clicking on the mouse, the MO shown in FIG.

It is possible to easily recognize which device among -1 to 16-8 is the copy source device and which device is the copy destination device.

In addition to the blinking of the online indicator lights 15 and 24, each device may be provided with an acoustic output element such as a buzzer to emit a sound. In the case of the MO library device, the accessor is driven and the operation sound or the like is generated. You may understand from.
FIG. 17 is an explanatory diagram of a copy information setting screen 125 used for the setting process of the copy information setting unit 74 provided in the host computer 10 in FIG. The copy information setting screen 125 is provided with check boxes 135, 145, 154, and 156 for designating the following four items.

The master device is an MO drive. Make the master device an MO library. Check the media capacity. Copy & Verify. First, the check box 135 is used to set the machine number # 0 of the group number G1 as in the device address information of FIG.
This is a check box for instructing to set the MO drive device, ie, the MO drive device 12-1 connected to the SCSI bus 14-1 in FIG. 8, as the master device as a copy source.

The next check box 145 is shown in FIG.
8A, the first MO drive and the second MO drive of the machine number # 0 of the group G0, that is, the MO drive 32-1 and the second MO drive 34-1 of the MO library device 16-1 of the SCSI bus 14-1 in FIG. This is a check box used as a copy source master device. The copy information setting unit 74 shown in FIG. 8 performs the system configuration control determined at that time on the basis of the operation by clicking the mouse on the check boxes 135 and 145 as to whether the copy source master device is the MO drive or the MO library. The automatic setting control for automatically setting the relationship between the copy source and the copy destination for the system configuration by the unit 72 is performed.

When the check box 154 on the copy information setting screen 125 in FIG. 17 is clicked with the mouse, whether or not the media capacity of all the cartridges in the copy MO library apparatus is equal to that of the cartridge of the master apparatus as the copy source is determined. It is possible to check whether write protection has been set in the copy destination cartridge and whether the copy destination medium is a cleaning medium before starting copying.

This medium capacity check processing is performed when a cartridge having a medium capacity different from that of the copy source cartridge exists at the copy destination, a write protected cartridge exists at the copy destination, and a cleaning cartridge exists at the copy destination. A shelf information window 176 as shown in FIG. 18 showing these check information is displayed.

The shelf information information window 176 shown in FIG. 18 contains 35 cartridges of the MO library device.
A table of the slot numbers 01 to 35 is displayed, and it can be seen that the cartridge is inserted into the slot numbers 01, 02, 03, 17, and 20 indicated by black circles. Among them, the slot number 02 indicates error information E, and indicates a size error indicating that the capacity is different from the capacity of the cartridge at the copy source.

The cartridge with the slot number 03 indicates that the cartridge has a capacity of 128 MB. This 128 MB cartridge can only be read by the MO library device used in the present invention.
Since it cannot be used as a copy destination cartridge, it is a type of error information. "*" Of slot number 17
Indicates that the cartridge is write protected.

“CLN” of the slot number 20 indicates that the cartridge is a cleaning cartridge. Further, "D1" and "D2" of the slot numbers 26 and 27 respectively indicate the first MO drive D1 and the second MO drive D1 built in the MO library device by the cartridge inserted in this slot.
Indicates that the drive D2 is set. By looking at such a shelf information screen 176 of the MO library device, it is possible to reliably prevent a problem that a cartridge causing an error prior to the copy processing is selected as a copy destination.

FIG. 19 shows a shelf error information window 180 displayed when a specific error is detected during copy processing.
This is an example. This shelf error information includes the library machine number,
It consists of a slot number and error content. The error information includes the following. MediaSize: A medium having a capacity different from that of the copy source is used at the copy destination. WriteProtect: A copy destination medium is write-protected. CLN Media: A cleaning medium is used. O provided in
The K key 182 is clicked with the mouse to continue copying even if an error occurs. (2) Automatic setting of copy information When the master device as the copy source device is set by clicking the check box 135 or 145 on the copy information setting screen 125 of FIG. 17 with the mouse, the copy mode according to the flowchart of FIG. The selection process is performed automatically.

In FIG. 20, first, it is checked whether or not the MO drive is included in the system configuration determined by the configuration control in step S1. If there is an MO drive device, the process proceeds to step S2, and the MO drive device becomes a copy source (master device). Subsequently, in step S3, it is checked whether there is one MO drive device. If there is one MO drive device, the process proceeds to step S4, and the copy mode 1
Is set as a copy mode in which the MO drive device is a copy source and all of the MO library devices are copy destinations. The basic mode of the copy mode 1 set in step S4 is as shown in FIG. 21, in which one MO drive is connected to the SCSI bus 14-1 from the SCSI card 18-1 connected as a host adapter to the host computer 10. Device 12
-1 and one MO library device 16-1 are connected. In this copy mode 1, the second MO library device 16
-2 is also included.

FIG. 22 shows an example of the apparatus configuration screen 162 in the system configuration in the copy mode 1 shown in FIG. In the device configuration screen 162, the device graphics of the MO drive device 12-1 and the MO library device 16-1 in FIG. 21 are displayed in a black frame and are mounted, and the remaining devices are displayed in a white frame. It can be seen from FIG.

That is, the system configuration of the minimum configuration in the present invention in FIG. 21 may correspond to the mounting state as in the device configuration screen 162 in FIG. 22, or the maximum configuration in the device configuration screen shown in FIG. In 162, the mouse is clicked on the disconnection box 166 for the device graphics other than the device graphics 12-1 and 16-1, so that
The state may be separated from the system configuration by software.

FIG. 23 shows a state in which the copy processing unit 70 of the host computer, the MO drive device 12-1 as the copy source device, and the MO library device 16-1 as the copy destination device in the copy mode 1 setting state of FIG. 6 is a time chart of a copy process performed. First, the copy processing unit 70 performs system configuration control and copy information setting processing as basic setting processing in step S1. When the basic settings are completed, the device configuration screen 16 shown in FIG.
By clicking the copy execution key 174 provided at the lower part of the mouse 2, the copy processing in step S 2 can be started. Of course, before starting the copy process, the copy source cartridge is inserted into the copy source MO drive device 12-1, and the MO library device 16 is inserted.
At -1, a plurality of cartridges as copy destinations are inserted.

With the start of the copy processing, the copy processing section 70 first starts the MO library device 16-in step S 3.
1 to issue a move command. Upon receiving the move command, the MO library device 16-1 transports the specified cartridge medium to the MO drive. Here, the MO library device 16-1 has the first MO drive and the second MO drive.
Since two drives are built in, two cartridges are transported to the respective drives as a medium 1 and a medium 2.

Next, the copy processing section 70 issues a copy source read command to the MO drive device 12-1 in step S4. In response to the read command, the MO drive device 12-1 reads the first sector in step S101 and transfers the read data to the copy processing unit 70, and stores the read data in the buffer in step S5.

Subsequently, the copy processing unit 70 proceeds to step S6
To write the write command to the first of the MO library device 16-1.
It is issued to the MO drive, and in response to this, step S2
In step 02, the sector data transferred by the write command is written to the medium of the first MO drive. Subsequently, the copy processing unit 70 issues a write command to the second MO drive of the MO library device 16-1 in step S7, and writes the same read data stored in the buffer as sector data in step S203.

By issuing the write command twice in steps S6 and S7, the MO library device 16-1 causes the first M
When the writing of the same sector data to the O drive and the second MO drive is completed normally, the copy processing unit 70 receives the confirmation response and determines in step S8 whether or not it is the last copy sector. Since it is not the last copy sector, a read command is again issued to the copy source in step S9,
In response, the MO drive device 12-1 proceeds to step S1.
In step 02, the own sector is read to transfer data. The above processing is repeated up to the last sector, and step S1 in FIG.
When the copy processing unit 70 confirms the last sector in 0, it issues a dummy sector write command to the MO library device 16-1 in step S11. In response to this dummy sector write command, the MO library device 16-1 writes dummy sector data to the medium of the first MO drive. At this time, if the capacity is the same as the copy source, the writing of the dummy sector results in an error. Returns an error response.

Next, in step S12, the write command of the dummy sector is again transmitted to the second
The data is issued to the MO drive to write the dummy sector. If the capacity is the same as that of the copy source, an error occurs in this case as well. In response to this error response, the copy processing unit 70 terminates the copy normally in step S13. The above processing,
This is repeated for all cartridges stored in the library device 16-1 as the copy destination.

Referring again to FIG. 20, if the number of MO drive devices is not one in step S3, that is, if there are a plurality of MO drive devices, the flow advances to step S5 to set the same host adapter as the copy mode 2. That is, SCSI
Copy mode 2 is set with the MO drive connected to the card as the copy source and the MO library as the copy destination.

The copy mode 2 is intended for a system form as shown in FIG. 25, for example. In FIG. 25, SC
SCSI bus 14 from SI cards 18-1 and 18-2
-1 and 14-2, one for each MO drive device 12-1,
12-2 and the MO library devices 16-1 and 16-3 are connected, and the MO drive devices 12-1 and 12-1 of each bus system are connected.
12-2 is the copy source, MO library device 16-1, 1
6-3 is the copy destination. In the copy mode 2, as shown in FIG. 26, the second library device 16-
The same applies to a system configuration in which 2, 16-4 are connected.

Referring again to FIG. 20, if there is no MO drive device in the system configuration in step S1,
Proceeding to step S6, the MO library device becomes the copy source. Further, in step S7, it is checked whether or not there is a host adapter, that is, a SCSI bus to which two MO library devices are connected. If there are two MO library devices, the process proceeds to step S8, and the copy mode 3 is automatically set.

The basic system form of the copy mode 3 is as shown in FIG.
SCSI bus 14- connected via I card 18-1
1 shows a case where two MO library apparatuses 16-1 and 16-2 are connected. In the copy mode 3, the same host adapter, that is, the same SCSI card 18-1 is used.
MO library devices 16-
1, 16-2, one of the library devices as a copy source,
Automatic setting of the copy mode with the other library device as the copy destination is performed.

In the present invention, the SCSI bus 14-1
Since the MO library device 16-1 is defined as the copy source master device, the MO library device 16-1 is the copy source and the MO library device 16-2 is the copy destination. In copy mode 3, as shown in FIG. 28, in addition to the basic configuration of FIG.
This also includes the case where a bus system including two MO library devices 16-3 and 16-4 is added via the -2 SCSI bus 14-2.

In these two bus systems, the MO library devices 16-1 and 16-3 are copy sources for each bus system, and the MO library devices 16-2 and 16-4 are copy destinations. This bus system can be expanded to a maximum of four systems as is clear from FIG. Referring again to FIG. 20, if there is no host adapter or bus system to which two MO library devices are connected in step S7, the process proceeds to step S9, and the host adapter 00, that is, the SCSI card 18- in FIG. MO on the SCSI bus 14-1
Check whether a library device is connected.
Here, the SCSI card 18 that is the host adapter 00
If the MO library device is connected to the SCSI bus 14-1 from -1, the process proceeds to step S10, and the copy mode 4 is automatically set.

FIG. 29 shows an example of the copy mode 4 set in step S10 of FIG. 20, which is operated by a mouse click operation of the connection box 164 or disconnection box 166 of the device graphics on the device configuration screen 162 as shown in FIG. , 4 SCSI buses 14-1 to 14
-4, one MO library device 16-1,
This is a case where the system configuration is such that 16-4, 16-6, and 16-8 are connected.

In copy mode 4 in which one MO library device is connected to each bus system, M
Since the O-library device 16-1 is defined as the master device, the O-library device 16-1 becomes a copy source, and the MO library devices 16-4, 16-6, and 16-8 of other bus systems become copy destinations. As described above, the check boxes 135 or 146 on the copy information setting screen 125 in FIG.

1 and the copy destination is the MO library device 16-2. In this copy process, the 230 MB cartridge 48-1, the 540 MB cartridge 48-2, and the 640 MB cartridge 48-3 are set as copy sources.
Is stored.

On the other hand, the copy destination MO library apparatus 16-2 also has the 230 MB cartridges 48-11 and 54.
The 0 MB cartridge 48-12 and the 640 MB cartridge 48-13 are stored. When cartridges of different capacities are stored in the copy source and the copy destination as described above, the copy processing unit 70 of the present invention controls the cartridges having the same capacity to perform copy processing.

FIG. 33B shows that the copy source is the MO drive device 12-1 and the copy destination is the MO library device 16-.
1, the copy destination cartridge 48 having the same capacity as the capacity 230 MB of the copy source cartridge 48-1.
The copy process is performed at -11. FIG. 34 is a flowchart of a copy process in which cartridge capacities are matched between the MO library apparatuses in FIG. First, in step S1, a move command is issued to the copy source MO library device 16-1, and the copy source cartridge is inserted into the first MO drive and the second MO drive in the order of the slot numbers. Specifically, the copy source 230 MB cartridge 48-1 is transported and inserted into the first MO drive, and the 540 MB cartridge 48-2 is transported and inserted into the second MO drive.

Next, in step S2, a move command is issued to the copy destination MO library device 16-2, and the copy source cartridge is inserted into the first MO drive and the second MO drive in the order of the slot numbers. That is, 230 MB stored in the slot of the copy destination MO library device 16-2.
The cartridge 48-11 is transported and inserted into the first MO drive, and the 540 MB cartridge 48-12 is inserted into the second MO drive.
Transfer to drive and insert.

Next, in step S3, a channel command word CCW for copying is issued, and a command is issued between the copy source first MO drive and the copy destination first MO drive, and between the copy source second MO drive and the copy destination second MO drive. In between, copy processing is performed in parallel. This copy process is a process of extracting sector data from the copy source cartridge in sector units and writing the sector data to the copy destination.

Regarding the sector-by-sector copy processing in step S3, whether or not an error has occurred is checked in step S4. For example, if the copy source cartridge capacity is larger than the copy destination cartridge capacity, the copy is performed in the middle of the sector unit copy. Since a write error occurs, the error information is written to the log at step S5. If no error occurs in step S4, the process proceeds to step S6 until writing of all sectors of the copy source cartridge to the copy destination is completed.
The copy processing in step S3 is repeated. When the writing of the last sector of the copy source cartridge is completed, step S7 is performed.
To check if the next one sector can be written to the copy destination cartridge.

For example, the copy source 230M shown in FIG.
Taking the copy process from the B cartridge 48-1 to the 230 MB cartridge 48-11 as the copy destination as an example, the next sector cannot be written after the end of the last sector write in step S7, resulting in a write error. In this case, it is determined that the cartridge capacity of the copy source and the cartridge capacity of the copy destination are the same, and a move command is issued in step S9 as normal termination of the copy processing, and the copied copy source cartridge and copy destination cartridge are stored in each library. Device 16
Return to the original slot in -1, 16-2.

On the other hand, in step S7, if the next sector after the writing of the last sector of the copy source can be written at the copy destination, for example, 230 MB of the copy source shown in FIG.
In the case of the cartridge 48-1, the capacity of the copy destination cartridge is larger than that of the 540 MB cartridge 48.
-12 or 640 MB cartridge 48-13. In this case, it is determined that the cartridge capacities of the copy source and the copy destination do not match, and error information indicating the capacity mismatch, for example, a size error E is left in the log in step S8.

The above processing of steps S1 to S9 is repeated until the processing of the last slot of the copy destination MO library apparatus 16-2 is determined in step S10, and when the processing of copying the cartridge of the last slot is completed, the flow proceeds to step S11. If there is error information in the log, step S
At 12, a list of failed cartridges is displayed on the display, for example, as in a shelf information window 176 in FIG.

By checking the shelf information window 176, the user can know that copying has been completed normally for the cartridges in the slots other than the slot displaying the error information. Open the tray and remove it from the slot.
FIG. 35 shows a case where the copy source in FIG.
21 is a flowchart of a copy process in which cartridge capacities are matched when the copy destination is set to 2-1 and the copy destination is set to the MO library device 16-1. First, in step S1, a move command is issued to the copy destination MO library apparatus 16-1, and the copy destination cartridges are placed in the first M
It is conveyed and inserted into the O drive and the second MO drive in order.

Next, in step S2, a copy channel command word CCW is issued, and the 230 MB cartridge 48-1 inserted into the first and second MO drives at the copy destination is changed from the 230 MB cartridge 48-1 at the copy source.
A parallel copy is performed in units of sectors for the 1 and 540 MB cartridges 48-12. In this case, the capacity of the two copy destination cartridges 48-11 and 48-12 is 2 with respect to the capacity of 230MB of the copy source cartridge 48-1.
Since the size is as large as 30 MB and 540 MB, no error occurs in step S3 during copying, and writing to the last sector of the copy source is normally performed in step S5. Subsequently, in step S6, the copy destination of the next one sector is written.

The copy destination 230 MB cartridge 48
Regarding -11, it is determined from the write error that the capacity is the same as that of the copy source. However, for the copy destination 540 MB cartridge 48-12, writing of the next one sector is normally performed, and the capacity does not match the copy source. It is determined that there is, and logging that leaves error information in the shelf information of the cartridge 48-12 is performed in step S7.

In step S8, a move command is issued to the copy destination MO library device 16-1, and the cartridges 48-11 and 48-12 are returned to their original slots. The processing of steps S1 to S8 is repeated until the slot. When the copy processing up to the last slot is completed, step S
It is checked in step 10 whether there is login error information. In this case, since there is login error information, this is displayed on the display as shelf information in step S11.

From this display, the 540 MB cartridges 48-12 and 64 shown in FIG.
The error information indicates that the capacity of the 0 MB cartridge 48-13 does not match the capacity of the copy source cartridge 48-1.
Cartridge 48-1 from library device 16-1
Only one can be taken out.

As described above, in the copy processing of FIG. 33, even if cartridges having different capacities from the copy source are mixed in the copy destination MO library apparatus, the copy destination cartridge having the same capacity as the copy source is normally processed. Since the result of the copying process can be obtained and the capacity of the cartridges at the copy destination does not need to be unified, the duplication work of a large number of cartridges using the library device as the copy destination can be easily performed and the usability is excellent. (2) Copy Process with Capacity Check FIG. 35 shows that the copy source is the MO drive device 12-1 and the copy destination is the MO library device 16 as shown in FIG.
9 is a flowchart of a copy process in which the capacity of the copy destination cartridge is detected prior to the copy process and the copy process is performed only for the copy destination cartridge having the same capacity as the copy source when −1 is set.

In the copy processing of FIG. 36, the same capacity check is performed on the copy source MO drive apparatus 12-1 and the copy destination MO library apparatus 16-1 in step S2 following step S1 as in FIG. A command is issued to detect the capacity, and it is checked in step S3 whether the copy source capacity and the copy destination capacity are the same. If the capacities of the copy source and the copy destination are the same, the process proceeds to step S5, where a copy channel command word is issued, and the first MO of the copy destination MO library device 16-1 is transmitted from the copy source MO drive device 12-1. The drive and the cartridge of the second MO drive are copied in parallel.

On the other hand, if the copy source capacity and the copy destination capacity do not match in step S3, the flow advances to step S4 to write the mismatched medium information into a log, issue a move command, and The previous cartridge is returned to the slot, the next cartridge is conveyed to the MO drive and inserted, and the process returns to step S2 to issue a capacity check command for the newly inserted copy destination cartridge to detect the capacity.

As a result, only cartridges having the same capacity as the copy source are to be subjected to copy processing after step S5. If copying is in progress, step S
It is checked in step 6 whether an error has occurred. If an error occurs, error information is written to a log in step S7. The copy processing in units of sectors in step S5 is repeated until the writing of all sectors to the copy destination is completed in step S8. When the writing is completed, a move command is issued in step S9 to return the copy destination cartridge to the original slot. .

At this time, in the copy processing of FIG. 35,
As in steps S6 and S7, after the end of the last sector writing, the capacity match and the mismatch are determined by writing to the copy destination of the next one sector. However, in the copy processing of FIG. This processing is unnecessary since the capacity match between the copy source and the copy destination has already been determined in the processing of steps S2 and S3.

Then, in step S10, the process proceeds to step S1 until the last slot of the copy destination MO library device 16-1.
When the copy processing of the last slot is completed, it is checked in step S11 whether there is error information in the log, and if there is error information, step S12 is performed.
A list of error information is displayed on the display as a shelf information window, and the copy destination cartridge excluding the cartridge in which the error has occurred is removed as normal termination.

FIG. 37 shows a copy process of the present invention for checking the capacity of the copy source and the copy destination before the start of the copy process.
34 is a flowchart applied to a copy process between the copy source MO library device 16-1 and the copy destination MO library device 16-2 in FIG. Even in the flowchart of FIG. 37, in steps S3 and S4, the copy source and copy destination MO library apparatuses 16-1 and 16 are used.
34, the capacity check command is issued to detect the capacity, and the process proceeds to the copy process from step S6 only after a capacity match is obtained. The copy process of FIGS. 36 and 37 is the same as the copy process of FIG. By reading and checking the cartridge capacity before the copy process, the copy process time can be greatly reduced as compared with the case where the capacity match is determined when the copy process of all the sectors of the copy source is completed. (3) Copy Process Allowing Difference in Media Capacity FIG. 38A shows the copy source MO library device 16-1.
FIG. 11 is an explanatory diagram of copy processing of the present invention in which a difference in cartridge capacity is permitted between the copy destination MO library apparatus 16-2 and the copy destination MO library apparatus 16-2. In this example, the copy source is a 230 MB cartridge 4
8-1, 540MB cartridge 48-2 and 640M
The B cartridge 48-3 contains cartridges of different capacities, whereas the copy destination MO library device 16-2 contains 640 MB cartridges 48-11, 48-12, and 48-13 which are larger than the copy source capacity. ing.

In the case where the copy source and copy destination cartridges have different capacities, in the embodiments shown in FIGS. 34 to 37, copy processing can be performed only between cartridges having the same capacity. In this case, if the copy destination capacity is larger than the copy source capacity, the copy process can be performed. FIG. 38B shows that the copy source is the MO drive device 1
2-1. This is a copy process allowing a difference in cartridge capacity when the copy destination is the MO library apparatus 16-1, and a copy destination having the same capacity or a larger capacity than the copy source 230MB cartridge 48-1. 230
Copy processing can be performed on the MB cartridges 48-11, 540MB cartridge 48-12 and 640MB cartridge 48-13 without being restricted by the difference in medium capacity.

FIG. 39 is a flowchart of the copy processing in FIG. 38A in which the difference in the cartridge capacity between the MO library apparatuses is permitted. In this copy process,
In steps S1 and S2, the copy source cartridge and the copy destination cartridge are transported and inserted into the first and second drives of the copy source and copy destination MO library apparatuses, respectively. Then, in step S3, a copy channel command word CCW is issued. Then, parallel copy processing is started in sector units.

If an error occurs in step S4 during copying, error information is written to a log in step S5. By detecting the occurrence of an error during copying in step S4 and writing the error information log in step S5,
The failure of the copy process when the capacity of the copy destination cartridge is smaller than the capacity of the copy source cartridge can be recognized after all the copy processes are completed by writing the error information to the log information.

The sector-by-sector copy processing in step S3 is repeated until the writing of all the sectors of the copy source to the copy destination is completed in step S6. When the write completion is determined, a move command is issued in step S7 and the copy source is issued. Then, the medium of the copy destination is returned to the original slot.
The process of S7 is repeated in step S8 up to the cartridge of the last slot of the copy destination.

When the copy processing of the cartridge in the last slot is completed, it is checked in step S9 whether or not there is error information in the log.
At 0, a list of failed media is displayed on the display as library shelf information. If there is a cartridge having a capacity smaller than the copy source cartridge in the shelf information, a write error occurs during the sector-by-sector copy process and is written to the log as error information, and the result is stored in the shelf information. Since it is displayed, the cartridge on which the error information is displayed may be excluded as the error cartridge.

FIG. 40 shows the MO drive device 12-1 as the copy source and the MO library device 1 as the copy destination in FIG.
FIG. 6 is a flowchart of a copy process in which a difference in cartridge capacity is allowed when 6-1 is set. Even in this copy process, a move command is issued to the copy destination MO library apparatus 16-1 in step S1 to insert a cartridge into each of the first MO drive and the second MO drive. The command word CCW is issued, and the parallel copy processing in sector units is repeated.

If the capacity of the medium at the copy destination is smaller than the capacity of the copy source during this copy, a write error occurs during the copy process, and it is determined in step S3 that an error has occurred. Error information is written to the log for the cartridge. Step S
The processing after step 5 is the same as the processing after step S6 in FIG.

In the copy processing allowing the difference in the cartridge capacities as described above, the copy processing can be performed normally from the error information generated during the copy without checking the capacities of the cartridge capacities of the copy source and the copy destination. A copy destination cartridge having a smaller capacity than the capacity of a copy source cartridge that has not been recognized, that is, a cartridge having error information can be recognized and eliminated, and copy processing can be performed normally when the copy destination cartridge capacity is equal to or larger than the copy source cartridge. Can be. In particular, as shown in FIG. 38 (A), copy processing can be appropriately performed in a case where the capacity of the copy destination cartridge is made equal to the capacity of the copy source cartridge. (4) Copy Processing Recognizing Recording Range FIG. 41 is an explanatory diagram of copy processing for recognizing the range of data actually recorded on the copy source cartridge 48-1 and copying the data to the copy destination cartridge 48-11. .
For example, file data is recorded in a range of 200 MB as a recording range of the copy source cartridge 48-1,
Recognizing this recording range 182, the copy destination cartridge 4
8-11, 200 MB of data having the same recording range 184 is written.

More specifically, the copy source cartridge 48-
1, the number of sectors or bytes is recognized from the file header or the like of the recording range 182, and copy processing for the recognized number of sectors or bytes is performed on the copy destination cartridge 48.
The copy process is terminated by performing the process for −11. FIG.
Is a copy process in which the cartridge recording range of the copy source is recognized. In this example, the copy source is the MO library device and the copy destination is the MO library device.

First, in steps S1 and S2, a move command is issued to each of the copy source and copy destination MO library apparatuses, and the first MOs are sequentially assigned from the slots.
The cartridge is transported and inserted into the drive and the second MO drive. Subsequently, in step S3, a search command for the recorded range is issued to the copy source MO library device,
For example, the number of recorded sectors is detected.

Subsequently, in step S4, a capacity check command is issued to the copy source and copy destination MO library apparatuses to detect the cartridge capacity, and in step S5, it is checked whether the copy source and copy destination cartridge capacities are the same. I do. If the cartridge capacities are different, the mismatched media information is written to the log in step S6, a move command is issued, the cartridge is exchanged with the MO drive in the copy destination MO library device, and the copy source and the copy source are changed in step S5. The process is repeated until the copy destination capacities match.

When it is determined in step S5 that the capacities of the copy source and the copy destination match, the process proceeds to step S7, in which a copy channel command word CCW is issued, and parallel copying in sector units is started. If an error occurs during copying, it is determined in step S8, and error information is written to a log in step S9. Parallel copy processing in sector units
The process is repeated until the writing of the detected sector indicating the recording content of the copy source is completed in step S10. When the writing of the recording range of the copy source is completed, a move command is issued in step S11 to copy the copy source and copy destination cartridges. , And the steps S1 to S11
Are repeated until the copy processing of the last slot of the copy destination is completed in step S12.

When the copy processing of the last slot is completed, it is checked at step S13 whether or not there is error information in the log. If there is, at step S4, a list of failed media is displayed on the display, and a series of error processing is performed. finish. FIG. 43 is a flowchart of a copy process in which the copy source recording range is recognized, in a case where the copy source is the MO drive device and the copy destination is the MO library device. Also in this case, basically, as in the case of the copy processing between the MO library apparatuses in FIG.
In step S9, the number of recorded sectors is detected by searching the recorded range of the copy source cartridge prior to the copy process. In step S9, the copy process is terminated when the number of recorded sectors in the copy source has been written during the copy process. I am trying to do it.

By performing the copy processing in which the recording range of the copy source cartridge is recognized as described above, the processing time required for the copy processing can be reduced by the amount that the copy of the range where the copy source is not recorded is not performed. (5) Merge Copy Process FIG. 44 shows the recorded data of a plurality of cartridges 48-1 to 48-5 provided in the copy source MO library device 16-1 in the cartridge 48-11 of the copy destination MO library device 16-2. This is a merge copy process that collectively records the data. For example, the copy source MO library device 16-1
Cartridges 48-1 to 48-5 have a recording range 184.
File data of 50 MB is recorded as -1 to 184-5, and this is detected before copying, and 200 MB is obtained as the total data amount of the copy source.

Then, the copy destination MO library device 16-
The cartridge capacity of the second cartridge 48-11 is detected, and if the total data amount of the copy source is 200 MB or more, merge copy processing is performed to combine them.
FIG. 45 is a flowchart of the merge copy process of FIG. First, in step S1, a channel command word is issued to the copy source MO library device 16-1, and a plurality of copy source cartridges are designated to check the size of all data. Subsequently, it is checked in step S2 whether the cartridge capacity is 640 MB or less, which is the maximum cartridge capacity that can be supported.

If the maximum cartridge capacity that can be supported is 640 MB or less, the flow advances to step S3 to insert the copy source cartridge in the order of the slot number into the copy source MO library apparatus 16-1, and then copy the copy destination MO library in step S4. A move command is issued to the library device 16-2, and the cartridges are inserted into the drive in the order of the slot numbers, and the capacity of the medium is checked.

Subsequently, in step S5, it is checked whether or not the capacity of the copy destination cartridge is larger than the total data amount of the copy source. If the capacity of the copy destination cartridge is insufficient, the process returns to step S6 to issue a move command. The cartridge with insufficient capacity is returned to the slot, and the next cartridge is taken out in step S4 to check the medium capacity. When it is determined in step S5 that the capacity of the copy destination cartridge is equal to or larger than the total data amount of the copy source, the process proceeds to step S7, in which a copy channel command word is issued to transfer the copy destination cartridge to the copy destination cartridge. Write the unit. If it is determined in step S8 that an error has occurred during writing in file units, error information is written to a log in step S9.

Until the writing of all the files of the copy source is completed in step S10, the writing of the remaining copy source cartridges to the copy destination cartridge in file units is repeated, and the writing of all the files of the copy source cartridge is completed. Then, in step S11, the copy destination and copy source MO library apparatuses 16-1 and 16-2 are used.
Return the drive cartridge to the original slot.

The processing in steps S3 to S11 described above is repeated in step S12.
Is repeated up to the last slot, and when the copy processing up to the last slot is completed, it is checked at step S13 whether or not there is error information in the log.
A list of failed media is displayed on the display, and the series of copy processing ends.

The data stored in the plurality of cartridges of the copy source is copied in units of files to the copy destination.
By the merge process of copying all cartridges together, a copy cartridge in which many cartridges are combined into one can be created, and the number of cartridges copied by copying can be reduced. (6) Group Copy Process FIG. 46 shows a copy process in which a plurality of copy source cartridges are copied to a copy destination from a copy source MO library device 16-1 to a copy destination MO library device 16-2 as one group. is there. That is, the cartridge 48- is stored in the copy source MO library apparatus 16-1.
There are five copy source groups 188 from 1 to 48-5,
Copy destination group 1 for cartridges of copy destination MO library apparatus 16-2 in units of copy group 188
Group copy of seven groups 90-1 to 190-7 is performed.

FIG. 47 shows another embodiment of the group copy according to the present invention, wherein the group copy is performed in the MO library apparatus. That is, for a total of 35 cartridges stored in the MO library apparatus 16-1, for example, the first five cartridges 48-1 to 48-4
8-5 is a copy source group 192, and the copy destination groups 194-1 to 194-1 are used for the remaining 30 cartridges.
4-6 is configured to perform group copy. 47. In the group copy within the same MO library device 16-1 in FIG. 47, the MO library device used in the present invention includes the first MO drive 32 and the second MO drive 34 as shown in FIG. Can be realized.

FIG. 48 is a flowchart of the group copy process of FIGS. 46 and 47. First, step S1
Then, the number of cartridges of the copy source and the copy destination device are checked. The check of the copy destination device is performed by using different M in FIG.
It is either between O library devices or the same MO library device in FIG. Next, in step S2, it is checked whether or not the number of sets (the number of groups) to be copied as the copy destination or all the cartridges in the MO library device to be the copy destination are to be the copy destinations.

Subsequently, in step S3, it is checked whether or not the copy destination is all cartridge media. If it is all cartridge media, in step S4, it is determined whether or not there is one set, that is, one group of copy destination cartridges. Check, 1
If there is a set, a group copy is performed in step S5. In this copy process, it is checked in step S6 whether or not the required number of copies have been made. If the required number of copies have been made, the process ends normally. In step S4, the copy destination cartridge is 1
If not, an error is displayed in step S7. If the required number of copies cannot be made in step S6, an error message is displayed in step S9.

On the other hand, if it is determined in step S3 that the copy destination is not the entire cartridge medium but the number of sets to be copied, the flow advances to step S8 to check whether the copy destination has the required number of cartridges. If so, the process proceeds to step S5 to perform group copy. If it is determined that the required number is not Step S8, Step S9
Will be displayed.

By performing a copy process for each of the required number of copies of the copy-source cartridges one by one by performing a copy process for each of the plurality of copy-source cartridges as one group, the copied cartridges are sorted and grouped. This eliminates the need for a user's operation of grouping the cartridges, and enables efficient copy processing in which a plurality of cartridges are grouped.

In the above embodiment, the case where the maximum configuration is four MO drive devices and eight MO library devices is taken as an example. However, the scale of these device configurations is not limited to the embodiment. It can be determined appropriately as needed. Further, in the above embodiment, an example of a device configuration in which two MO drives are built in as the MO library device is taken as an example, but it is needless to say that an MO library device in which one MO drive is built in may be used. . Further, the capacity of the MO cartridge used in the present invention is not limited by the embodiment.

The computer-readable recording medium recording the copy processing program of the present invention includes:
There are a removable portable storage medium such as a CD-ROM and a floppy disk, a storage device of a program provider that provides a program via a line, and a memory device such as a RAM or a hard disk of a processing device in which the program is installed. The program provided by the recording medium is loaded into the processing device and executed on the main memory.

[0158]

As described above, according to the present invention, an actual MO library device or MO can be set by clicking the check area for device confirmation provided in the device graphics on the operation screen of the copy process with the mouse. The drive unit responds by flashing the indicator light, and the user does not need to check the device bus ID etc. of the device each time and refer to the environment setting file on the copy processing side. The original and copy destination device environments can be easily recognized, and the operability of medium insertion and medium removal in copy processing can be greatly improved.

By providing system connection and disconnection operation functions in the device graphics on the device configuration screen, it is possible to arbitrarily implement a software-based system form as needed within the range of the mounting state of the device. The change of the system form can be arbitrarily made as necessary without changing the actual hardware connection, and the degree of freedom of the system form of the copy processing can be greatly improved.

For setting copy information necessary for copy processing, for example, by simply selecting a copy source device, a copy mode for determining an optimal correspondence between a copy source and a copy destination suitable for the system configuration at that time is set. Even if the number of MO drive devices and MO library devices used for copy processing increases, the user can specify the copy source device only, and the user can specify the copy mode by using the optimum copy mode. It can be performed.

By preparing the copy information setting screen required for the copy process, the user can freely set the correspondence between the copy source and the copy destination and realize the copy process with a high degree of freedom. Further, as a copy process, a copy process in which the media capacity of the copy source and the copy destination are matched, a copy process in which the media capacity of the copy source and the copy destination are checked to check the media capacity, and Copy processing that allows for differences in the media capacity provided that it is equal to or greater than the capacity, copy processing excluding the unrecorded area where the recording range of the copy source has been recognized, and checking the total data amount of multiple By providing various forms of copy processing, such as merge copy processing for copying and copying on a single medium collectively, and group copy processing for copying a plurality of copy source media as one group in a group unit, medium capacities are different and different capacities are provided. Even if multiple media are mixed, optimal copy processing is performed efficiently, and the processing time required for copy processing is reduced as much as possible. Rate specific copy processing can be realized.
