Identify the drive to be used in the target log. Further, the test command issuing unit 23 monitors the log of the physical control unit 11 or the virtual control unit 12 corresponding to the drive specified by the drive specifying unit 22. Furthermore, when the test command issuing unit 23 detects the monitoring target log related to the test command to be executed from the log monitoring result of the physical control unit 11 or the virtual control unit 12, the test command issuing unit 23 stores the execution target test command in the virtual tape device 2. Issued to test subjects.

  In the first embodiment, since the test command corresponding to the operation verification in the virtual tape device 2 is issued, the operation verification in the virtual tape device 2 can be automatically performed without requiring manual operation.

  Further, in the first embodiment, even when the log monitoring result of the overall control unit 13 in the virtual tape device 2 is the monitoring target log, when the monitoring target log is detected from the log monitoring result of the overall control unit 13, this monitoring target log A test command corresponding to is issued. As a result, a test command triggered by the log of the overall control unit 13 can be issued.

  Further, in the first embodiment, even when the log monitoring result of the physical control unit 11 or the virtual control unit 12 in the virtual tape device 2 is set as the monitoring target log, when the monitoring target log is detected, the test corresponding to the monitoring target log is performed.

As a result, a test command triggered by a log of the physical control unit 11 or the virtual control unit 12 can be issued, so that command issuance can be realized at a detailed timing using the log of the physical control unit 11 or the virtual control unit 12.

  FIG. 2 is a block diagram illustrating the internal configuration of the virtual tape device according to the second embodiment, and FIG. 3 is a block diagram illustrating the internal configuration of the RAS test device according to the second embodiment. The virtual tape device 2A shown in FIG. 2 is connected to the host device 3 with a connection cable and also connected to a RAS (Reliability Availability Serviceability) test device 1A via a LAN (Local Area Network). The virtual tape device 2A includes a plurality of components, and includes a virtual tape drive 14, a physical tape drive 15, an integrated device processor 11A, an integrated channel processor 12A, a virtual library processor 13A, and a switch 16.

  The physical tape drive 15 includes a physical drive (Drive: hereinafter simply referred to as DRV) 15A corresponding to a tape cartridge, and each DRV 15A (DRV0 to DRVx) stores data. The virtual tape drive 14 is composed of a disk array device (hereinafter simply referred to as TVC) 14A, and virtually stores data stored in the DRV 15A.

  An integrated channel processor (hereinafter simply referred to as ICP) 12A corresponds to a control unit that constructs a virtual tape drive 14 and controls communication with an interface with the host apparatus 3. The ICP 12A is connected to each virtual drive in the virtual tape drive 14 and is configured by a plurality of ICP0 to ICP (n-1). The cable between the ICP 12A and the host device 3 realizes high-speed and large-capacity data transfer. An integrated device processor (hereinafter simply referred to as IDP) 11A corresponds to a control unit that controls communication with a plurality of DRVs 15A in the physical tape drive 15. The IDP 11A is connected to each DRV 15A in the physical tape drive 15 and is configured by a plurality of IDP0 to IDP (n-1). A virtual library processor (hereinafter simply referred to as VLP) 13A corresponds to a control unit that manages the database of the virtual tape drive 14 and the physical tape drive 15 and controls the entire virtual tape device 2A. The switch 16 includes two types of switches: a fiber channel (hereinafter simply referred to as FC) 16A connected to an optical fiber that realizes high-speed transfer over a long distance section, and a LAN switch 16B.

  The RAS test apparatus 1A corresponds to, for example, the same control unit as the ICP 12A, IDP 11A, and VLP 13A. The RAS test device 1A is connected to the host device 3 and the switch 16 by TCP / IP protocol, and has a remote access function such as TELNET / fiber transfer protocol (hereinafter simply referred to as FTP) to each component in the virtual tape device 2A. It becomes feasible. The RAS test apparatus 1A can execute a host job, monitor a log in the virtual tape apparatus 2A, issue a command to each component, and the like using a remote access function.

  After issuing the test command, the RAS test apparatus 1A compares the test result corresponding to the test command with the expected value of the test command, and ends the test command if the comparison result is within the allowable range. In addition, the RAS test apparatus 1A compares and collates the test result corresponding to the test command with the expected value, and when the comparison result is out of the allowable range, recovers the failure generated by the test command and executes the next test. .

  The RAS test apparatus 1A shown in FIG. 3 includes a communication interface 31, an operation unit 32, a display unit 33, a storage unit 34, and a test control unit 35. The communication interface 31 connects the host device 3 and the switch 16 in the virtual tape device 2A via a LAN. The operation unit 32 inputs various instructions. The display unit 33 displays various information. The storage unit 34 stores various information. The test control unit 35 controls the entire RAS test apparatus 1A.

  The storage unit 34 includes a command table 41, an expected value table 42, and a log conversion table 43. The command table 41 manages a monitoring target log indicating the timing of issuing the test command for each test command to the test target of each component in the virtual tape device 2A. Note that the monitoring target log for issuing the test command includes, for example, a communication log between the IDP 11A and the physical tape drive 15 and a timing triggered by the communication log between the ICP 12A and the host device 3. However, actually, there are a plurality of virtual tape drives 14 and physical tape drives 15 in the virtual tape device 2A, and the IDP 11A and the ICP 12A are controlled. However, there are control logs corresponding to the number of drives. Therefore, the virtual tape device 2A arbitrarily determines which drive should be used.

  FIG. 4 is an explanatory diagram illustrating a monitoring target log using the IDP 11A log. For example, "When a write command is issued at the timing when the write command is issued after the physical volume" VOL A "is mounted on any one of the DRVs on the IDP", it corresponds to the failure command The monitoring target log to be displayed is as shown in FIG. FIG. 5 is an explanatory diagram showing a monitoring target log using the ICP 12A log. For example, “After the logical volume“ A ”is mounted on any one of the plurality of virtual tape drives (LD: V000 to V4FF) on the ICP, a failure command is issued at the timing when the write command is issued. ", The monitoring target log corresponding to this failure command is as shown in FIG.

  FIG. 6 is an explanatory diagram showing an example of the contents of the expected value table 42. The expected value table 42 shown in FIG. 6 manages the expected value for evaluating the test result when the test command is issued for each test command content and test timing for each test target. Note that the expected value corresponds to a legitimate value that should be normally obtained as a test result when the test command is issued.

  FIG. 7 is an explanatory diagram showing an example of the table contents of the log conversion table 43. The log conversion table 43 shown in FIG. 7 corresponds to a table for converting the monitoring target log of the ICP 12A or IDP 11A using the drive of the physical tape drive 15 or the virtual tape drive 14 into the monitoring target log of the VLP 13A. The log conversion table 43 manages the log name and trigger contents of the monitoring target log before conversion and the log name and trigger contents of the monitoring target log after conversion in association with each other. The log name of the monitoring target log corresponds to “log DRV *” for the IDP11A log, “log V ***” for the ICP12A log, and “log vvvv” for the VLP13A log. In the log conversion table 43, for example, when the monitoring target log before conversion is the log of ICP 12A and the trigger content is “write”, the trigger content of the monitoring target log of the converted VLP 13A corresponds to “mount”. That is, the VLP 13A issues a “mount” command to the DRV 15A of each physical tape drive 15 of the IDP 11A or each virtual tape drive 14 of the ICP 12A. As a result, the mount destination physical tape drive name (DRV) and virtual tape drive name appear in the VLP 13A log.

  The test control unit 35 includes a storage control unit 51, a command selection unit 52, a monitoring target log determination unit 53, a drive identification unit 54, a log monitoring unit 55, a test command issue unit 56, and a test evaluation unit 57. Have The storage control unit 51 stores and controls the command table 41, the expected value table 42, and the log conversion table 43 in the storage unit 34. The command selection unit 52 selects a designated test command from the command table 41 in accordance with, for example, a designation operation or program of the operation unit 32.

  When the command selection unit 52 selects a test command, the monitoring target log determination unit 53 searches the command table 41 for a monitoring target log corresponding to the test command. Further, the monitoring target log determination unit 53 determines whether or not the monitoring target log obtained from the search result is a log of the ICP 12A or IDP 11A. Note that the monitoring target log determination unit 53 determines that the log is a log of IDP 11A when the log name of the monitoring target log is “log DRV *”. Furthermore, when the log name of the monitoring target log is “log V ***”, the monitoring target log determination unit 53 determines that the log is ICP 12A. Furthermore, when the log name of the monitoring target log is “log vvvv”, the monitoring target log determination unit 53 determines that the log is the VLP 13A log.

  For example, the log monitoring unit 55 monitors the log of the specified ICP 12A, IDP 11A, or VLP 13A via the communication interface 31. When the monitoring target log is a log of ICP 12A or IDP 11A through the monitoring target log determination unit 53, the drive specifying unit 54 specifies a drive to be used for specifying the ICP 12A or IDP 11A. When the monitoring target log is a log of the VLP 13A, when the monitoring target log is detected from the log monitoring result of the VLP 13A, the test command issuing unit 56 issues a test command corresponding to the monitoring target log via the communication interface 31. In addition, when the monitoring target log is an IDP 11A or ICP 12A log and the monitoring command log is detected from the log monitoring result of the ICP 12A or IDP 11A, the test command issuing unit 56 sends a test command corresponding to the monitoring target log via the communication interface 31. Issue.

  The drive specifying unit 54 includes a monitoring target log converting unit 54A, a drive name specifying unit 54B, and a drive name setting unit 54C. The monitoring target log conversion unit 54A is activated when the monitoring target log determination unit 53 determines that the monitoring target log is not a log of the VLP 13A, that is, a log of ICP 12A or IDP 11A. The monitoring target log conversion unit 54A converts the monitoring target log of the VLP 13A corresponding to the monitoring target log of the ICP 12A or IDP 11A using the log conversion table 43 according to the activation operation. When the monitoring target log conversion unit 54A converts the monitoring target log of the IDP 11A or ICP 12A into the monitoring target log of the VLP 13A, the monitoring target log of the IDP 11A or ICP 12A before conversion is temporarily stored in the storage unit 34. FIG. 8 is an explanatory diagram illustrating an example of an operation for converting the monitoring target log of the IDP 11A into the monitoring target log of the VLP 13A. As shown in FIG. 8, the monitoring target log conversion unit 54A converts the monitoring target log of the IDP 11A into the monitoring target log of the VLP 13A.

  Further, the drive name specifying unit 54B obtains the monitoring result of the log of the VLP 13A through the log monitoring unit 55 when converted to the monitoring target log of the VLP 13A. When the drive name identification unit 54B detects the monitoring target log of the VLP 13A from the monitoring result of the VLP 13A log, the drive name specifying unit 54B ends the monitoring operation of the VLP 13A log. Further, the drive name specifying unit 54B specifies the drive name used for the monitoring target log from the log file of the log monitoring result of the VLP 13A.

  FIG. 9 is an explanatory diagram showing an example of an operation for identifying a drive name used for the IDP 11A monitoring target log from the log monitoring result of the VLP 13A. For example, when the drive name specifying unit 54B detects “mount VOL A” that is the trigger content of the monitoring target log of the VLP 13A from the log monitoring result of the VLP 13A, as shown in FIG. 9, the drive name used for the monitoring target log Specify “DRV1”. That is, when the monitoring target log before log conversion is an IDP 11A log, the drive name specifying unit 54B specifies an arbitrary drive name from a plurality of drive names used for the physical tape drive 15. FIG. 10 is an explanatory diagram showing an example of an operation for specifying a drive name used for the monitoring target log of the ICP 12A from the log monitoring result of the VLP 13A. For example, as shown in FIG. 10, when the drive name specifying unit 54B detects “mount A” that is the trigger content of the monitoring target log of the VLP 13A from the log monitoring result of the VLP 13A, the drive name used for the monitoring target log “ Specify V000 ". That is, when the monitoring target log before log conversion is an ICP 12A log, the drive name specifying unit 54B specifies an arbitrary drive name from a plurality of drive names used for the virtual tape drive 14.

  The drive name setting unit 54C sets the drive name specified by the drive name specifying unit 54B to the monitoring target log before conversion stored in the storage unit 34, and uses the set monitoring target log as the test command issuing unit 56. Set to. FIG. 11 is an explanatory diagram illustrating an example of an operation for setting a drive name in the monitoring target log of the IDP 11A before conversion. For example, when the drive name setting unit 54C is identified as the drive name “DRV1”, the drive name setting unit 54C sets “DRV1” as the log name of the monitoring target log of the IDP 11A before conversion as shown in FIG. Replace with “log DRV1”. FIG. 12 is an explanatory diagram showing an example of an operation for setting a drive name in the monitoring target log of the ICP 12A before conversion. For example, when the drive name setting unit 54C is identified as the drive name “V000”, the drive name setting unit 54C sets “V000” as the log name of the monitoring target log of the ICP 12A before conversion as shown in FIG. Replace with “log V000”.

  For example, when the IDP 11A monitoring target log in which the drive name is set is set, the test command issuing unit 56 monitors the log of the specific drive of the IDP 11A through the log monitoring unit 55. When the test command issuing unit 56 detects the monitoring target log from the monitoring result of the log of the specific drive of the IDP 11A, the test command issuing unit 56 issues the test command selected by the command selection unit 52. For example, when the monitoring target log with the log name “log DRV1” and the trigger content “write VOL A” is set, the test command issuing unit 56 monitors the log with the drive name “DRV1”. When the test command issuing unit 56 detects “write VOL A” from the log monitoring result of the drive name “DRV1”, the test command issuing unit 56 issues a test command corresponding to the monitoring target log. Similarly, the test command issuing unit 56 detects the monitoring target log from the log monitoring result of the ICP 12A through the log monitoring unit 55 when the monitoring target log of the ICP 12A is set, and the test command selected by the command selection unit 52 Issue.

  The test evaluation unit 57 collects test results corresponding to the test commands issued by the test command issuing unit 56 through the communication interface 31. When the test evaluation unit 57 collects the test results corresponding to the test command, the test evaluation unit 57 includes an expected value determination unit 57A that determines whether or not the expected value corresponding to the test command is in the expected value table 42.

  When the expected value determination unit 57A has an expected value corresponding to the test command in the expected value table 42, the test evaluation unit 57 reads the expected value corresponding to the test command from the expected value table 42, and uses the expected value as the test command. The corresponding test result is compared with the expected value. When the comparison result between the test result corresponding to the test command and the expected value is within the allowable range, the test evaluation unit 57 recovers the failure generated by the test command and executes the next test. Further, when the comparison result between the test result corresponding to the test command and the expected value is out of the allowable range, the test evaluation unit 57 displays a warning display on the display unit 33.

  When the expected value determination unit 57A does not have an expected value corresponding to the test command in the expected value table 42, the test evaluation unit 57 sets the test result corresponding to the test command as an expected value in the expected value table 42. Remember.

  Next, the operation of the RAS test apparatus 1A according to the second embodiment will be described. FIG. 13 is an explanatory diagram showing the operation of the virtual tape device 2A when the test command is issued by the RAS test device 1A. The RAS test apparatus 1A shown in FIG. 13 monitors the log of the VLP 13A via the LAN switch 16B. Furthermore, when the RAS test apparatus 1A detects the monitoring target log from the log monitoring result of the VLP 13A, it issues a test command for shutting off the port P2 of the FC switch 16A. The virtual tape device 2A is in a state where the port P2 of the FC switch 16A is blocked in accordance with the test command of the RAS test device 1A. The RAS test 1A collects test results corresponding to the test command, and compares and compares the expected value of the test command and the test result.

  FIG. 14 is a flowchart illustrating an internal processing operation of the RAS test apparatus 1A related to the test command issuing process according to the second embodiment. The test command issuance process shown in FIG. 14 refers to the test command issued in the virtual tape device 2A when the monitoring target log corresponding to the test command is detected from the log monitoring result in the virtual tape device 2A on the RAS test device 1A side. It is a process issued to the target.

  In FIG. 14, the monitoring target log determination unit 53 of the test control unit 35 in the RAS test apparatus 1A determines whether or not the monitoring target log corresponding to the test command selected by the command selection unit 52 is a log of the ICP 12A or IDP 11A. Is determined (step S11). When the monitoring target log is an ICP 12A or IDP 11A log (Yes in step S11), the monitoring target log conversion unit 54A of the drive specifying unit 54 converts the ICP 12A or IDP 11A monitoring target log into a corresponding VLP 13A monitoring target log (step S11). S12). The monitoring target log conversion unit 54A converts the monitoring target log of the ICP 12A or IDP 11A into the monitoring target log of the VLP 13A based on the table contents of the log conversion table 43 (see FIG. 8). The monitoring target log conversion unit 54A temporarily stores the monitoring target log of the ICP 12A or IDP 11A immediately before conversion in the storage unit 34.

  As shown in FIG. 15, the drive name specifying unit 54B of the drive specifying unit 54 monitors the log of the VLP 13A through the log monitoring unit 55 (step S13), and detects whether the VLP 13A monitoring target log is detected from the log monitoring result of the VLP 13A. Is determined (step S14). FIG. 15 is an explanatory diagram showing an example of the operation of monitoring the log of the VLP 13A. When the drive name specifying unit 54B detects the monitoring target log of the VLP 13A (Yes in step S14), the drive name used in the monitoring target log before conversion is obtained from the log monitoring result of the VLP 13A as shown in FIGS. Specify (step S15).

  When specifying the drive name, the drive name setting unit 54C of the drive specifying unit 54 sets the drive name in the monitoring target log before conversion temporarily stored in the storage unit 34 as shown in FIGS. Step S16). When the test command issuing unit 56 sets the drive name in the monitoring target log of the ICP 12A or IDP 11A before conversion, the log of the ICP 12A or IDP 11A corresponding to the drive name is sent through the log monitoring unit 55 as shown in FIGS. Monitor (step S17). 16 is an explanatory diagram showing an example of an operation for monitoring a log of a specific drive name on the IDP 11A, and FIG. 17 is an explanatory diagram showing an example of an operation for monitoring a log of a specific drive name on the ICP 12A. The test command issuing unit 56 determines whether the monitoring target log of the ICP 12A or IDP 11A set from the monitoring result of the log of the ICP 12A or IDP 11A has been detected (step S18).

  When the test command issuing unit 56 detects the monitoring target log of the ICP 12A or IDP 11A (Yes at Step S18), the test command issuing unit 56 issues a failure command to the test target (Step S19), and ends this processing operation.

  In addition, when the monitoring target log is not the ICP 12A or VLP 13A log, that is, the VLP 13A log (No at Step S11), the test command issuing unit 56 monitors the VLP 13A log through the log monitoring unit 55 (Step S20). The test command issuing unit 56 determines whether the monitoring target log of the VLP 13A is detected from the monitoring result of the VLP 13A log (step S21). When the test command issuing unit 56 detects the monitoring target log of the VLP 13A (Yes at Step S21), the test command issuing unit 56 proceeds to Step S19 in order to issue a failure command corresponding to the monitoring target log.

  If the monitoring target log is not detected from the log monitoring result of the VLP 13A (No at Step S14), the drive name specifying unit 54B proceeds to Step S13 in order to continue the log monitoring of the VLP 13A. When the test command issuing unit 56 does not detect the monitoring target log from the log monitoring result of the ICP 12A or IDP 11A (No at Step S18), the test command issuing unit 56 proceeds to Step S17 to continue the log monitoring of the ICP 12A or IDP 11A. When the test command issuing unit 56 does not detect the monitoring target log from the log monitoring result of the VLP 13A (No at Step S21), the test command issuing unit 56 proceeds to Step S20 to continue the log monitoring of the VLP 13A.

  In the test command issuance process shown in FIG. 14, when the monitoring target log is an IDP 11A or ICP 12A log, the monitoring target log is converted to the VLP 13A monitoring target log, and the drive used in the monitoring target log before conversion from the VLP 13A monitoring result Specify a name. In the test command issuance process, when the drive name is specified, the drive name is set in the monitoring target log before conversion, and the IDP 11A or ICP 12A log corresponding to the drive name is monitored. Further, in the test command issuing process, when the monitoring target log is detected from the monitoring result, a test command corresponding to the monitoring target log is issued. That is, in the test command issuance process, not only the VLP 13A log but also the test command using the IDP 11A or ICP 12A log as a trigger can be issued.

  Next, an expected value table update process for updating the expected value table 42 of the RAS test apparatus 1A will be described. The expected value table update process is to acquire a test result corresponding to a test command, and when an expected value corresponding to the test result is not in the expected value table 42, the test result corresponding to the test command is used as an expected value. This is a process for updating the memory in the expected value table 42. FIG. 18 is an explanatory diagram showing an example of the operation of the RAS test apparatus 1A related to the expected value table update process.

  The RAS test apparatus 1A shown in FIG. 18 acquires a test command (test command content) to be executed and a monitoring target log (test timing) from the command table 41. When the RAS test device 1A detects the test command monitoring target log from the log monitoring result of the log monitoring unit 55, the RAS test device 1A issues the test command to the test target in the virtual tape device 2A. The test evaluation unit 57 in the test control unit 35 of the RAS test apparatus 1A collects test results corresponding to the test command. Furthermore, when collecting the test results corresponding to the test command, the test evaluation unit 57 determines whether or not the expected value corresponding to the test command is in the expected value table 42. When the expected value corresponding to the test command is not in the expected value table 42, the test evaluation unit 57 updates the test result corresponding to the test command as the expected value in the expected value table 42. The expected value table 42 manages test command contents and test timing for each test object, and manages expected values for each test timing.

  In other words, the RAS test apparatus 1A uses the expected value of the test command content and the test timing related to the test timing even if the test command content of the test command and the expected value for each test timing are not stored in the expected value table 42 in advance. Can be updated in the expected value table.

  In addition, when the expected value corresponding to the test command is in the expected value table 42, the test evaluation unit 57 compares and compares the expected value and the test result corresponding to the test command. When the expected value and the test result corresponding to the test command are within the allowable range, the test evaluation unit 57 recovers the failure generated by the test command and executes the next test. Further, when the expected value and the test result corresponding to the test command are outside the allowable range, the test evaluation unit 57 displays a warning display on the display unit 33.

  In the second embodiment, since the test command corresponding to the operation verification in the virtual tape device 2A is issued, the operation verification in the virtual tape device 2A can be automatically performed without requiring manual operation.

  Further, in the second embodiment, even when the log monitoring result of the VLP 13A in the virtual tape device 2A is set as the monitoring target log, when the monitoring target log is detected from the log monitoring result of the VLP 13A, a test command corresponding to the monitoring target log is issued. Issue. As a result, a test command triggered by the VLP 13A log can be issued.

  Further, in the second embodiment, even when the log monitoring result of the IDP 11A or ICP 12A in the virtual tape device 2A is set as the monitoring target log, if the monitoring target log is detected from the log monitoring result of the IDP 11A or ICP 12A, the monitoring target log is supported. Issue the test command. As a result, a test command can be issued using the IDP 11A or ICP 12A log as a trigger, so that the command can be issued at a detailed timing using the IDP 11A or ICP 12A log.

  In the second embodiment, when the test result corresponding to the test command is collected, it is determined whether or not the expected value corresponding to the test command is in the expected value table 42. The corresponding test result is stored in the expected value table 42 as an expected value. That is, it is possible to sufficiently cope with the addition of a new test command while greatly reducing the trouble of creating an expected value table in which the expected value for each test command is stored in advance as in the prior art.

  In addition, each component of each part illustrated does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each part is not limited to the one shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in arbitrary units according to various loads and usage conditions. Can be configured.

  Furthermore, various processing functions performed in each device are performed on a CPU (Central Processing Unit) (or a microcomputer such as an MPU (Micro Processing Unit), MCU (Micro Controller Unit), etc.) in whole or in part. You may make it perform. Various processing functions may be executed entirely or arbitrarily on a program that is analyzed and executed by a CPU (or a microcomputer such as an MPU or MCU) or hardware based on wired logic. Needless to say.

  By the way, the various processes described in the present embodiment can be realized by executing a prepared program on a computer. Therefore, in the following, an example of a computer that executes a program having the same function as in the above embodiment will be described with reference to FIG. FIG. 19 is a diagram illustrating a computer that executes a maintenance test program.

  As shown in the figure, a computer 200 as a maintenance test program is configured by connecting a hard disk drive (HDD) 210, a random access memory (RAM) 220, a read only memory (ROM) 230, and a CPU 240 via a bus 250. The

  The ROM 230 stores in advance a maintenance test program that exhibits the same functions as in the above-described embodiment, that is, a management program 231, a specific program 232, and a test command issue program 233 as shown in FIG. Note that the programs 231 to 233 may be appropriately integrated or distributed in the same manner as each component of the maintenance test apparatus 1 shown in FIG.

  Then, the CPU 240 reads out these programs 231 to 233 from the ROM 230 and executes them, so that each program 231 to 233 functions as a management process 241, a specific process 242, and a test command issue process 243 as shown in FIG. To come. Each process 241 to 243 corresponds to the command management unit 21, the drive specifying unit 22, and the test command issuing unit 23 shown in FIG.

  The CPU 240 is a test command issued to a test target in the virtual tape device 2 and a monitoring target log that is a log of the physical control unit 11, the virtual control unit 12, or the overall control unit 13, indicating the timing at which the test command is issued. Are managed in the RAM 220 in association with each other. The CPU 240 monitors the log of the overall control unit 13 in the virtual tape device 2 according to the test command to be executed in the RAM 220 and the monitoring target log designation operation, and relates to the test command to be executed from the monitoring result. Identify the drive to be used in the monitored log. When the CPU 240 monitors the log of the virtual control unit 12 or the physical control unit 11 corresponding to the identified drive and detects the monitoring target log related to the test command to be executed from the monitoring result, the test command of the execution target Is issued to the test subject.

  As a result, a test command triggered by a log of the physical control unit 11 or the virtual control unit 12 can be issued, so that command issuance can be realized at a detailed timing using the log of the physical control unit 11 or the virtual control unit 12.
