Abstract

PROBLEM TO BE SOLVED: To surely leave fault information in a log medium by repeating rewrit ing after insertion into a normal log medium even if the storage of fault informa tion into the log medium has failed. SOLUTION: When a diagnosis processor 2 detects the occurrence of the fault of a processor 1, it stores fault information into a self RAM area and writes it into a log medium 8 during mounting. When writing fails, an FD control circuit 3 leaves a 'failed' result in an FD write result storage circuit 6. When an FD write retry control circuit 5 detects 'failure', it issues the exchange request of a log medium 4 and a command for retrying writing to the diagnosis processor 2. The diagnosis processor 2 displays 'log medium exchange' on LED on a control panel 7. When the medium is exchanged into a normal log medium 9, display disappears and the diagnosis processor 2 writes fault information stored in the RAM area into the normal log medium 9 with the matching of the attention of log medium exchange and the write retry command.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a log data storage device for storing failure information collected on a RAM of a maintenance diagnosis processor in a log medium.

[0002]

2. Description of the Related Art A conventional log data storage device of this type is
If the log medium that captures the failure information fails to write the failure information due to reasons such as unimplemented media or defective media (including different media), stop collecting logs and maintain by remote maintenance using a communication line. RAM for diagnostic processor
The fault information left above is read out, for example, on the control panel.

[0003]

In this conventional log data storage device, when the log medium for fetching the failure information fails to write the failure information due to the reason that the medium is not mounted or the medium is defective, the failure to the log medium is caused. Since the information is written only once and there is no retry function, the failure information that could not be stored is not written again to the log medium. Therefore, when the power is turned off, the failure information is reduced and the log information is also saved. There is a problem that it is not possible to remove the medium and analyze the failure information in another device.

An object of the present invention is to notify that failure information has not been stored in a log medium and to insert a normal log medium,
By re-executing the writing of the failure information that has not been stored, the failure to store the failure information due to the cause of the log medium is eliminated.

[0005]

A device of the present invention is a log data storage device for storing failure information in a log medium, comprising:
When failure information cannot be stored due to a problem on the log medium side and the normal log medium is loaded, the failure information is written to the normal log medium.

In the present invention, the failure result in which the failure information could not be stored in the log medium is left. For this reason,
Based on the result of the failure, it is possible to issue a request for replacing the log medium to a normal one to the operator and replace it with a writable log medium.

Also, a retry request issued based on the failure result,
When the two conditions of the writable log medium insertion attention match, the fault information is written again. Therefore, it is possible to recognize the failure information storage result and rewrite it in the log medium.

[0008]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a log data storage device according to an embodiment of the present invention, which includes a processor 1, a diagnostic processor 2, an FD control circuit 3, an FDD 4, and an FD.
A write retry control circuit 5, an FD write result storage circuit 6, a control panel 7, a log medium (write failure) 8, a log medium (normal) 9, and a diagnostic interface 10.

The operation of this embodiment is as follows.

When the diagnostic processor 2 detects a fault occurrence in the processor 1 via the diagnostic interface 10, the fault information of the processor 1 is once notified to the RA of the diagnostic processor 2 itself.
Store in M area. The diagnostic processor 2 processes data from the collected failure information into a format format to be stored in the log medium 8 and also designates the storage cylinder position of the log medium 8 and outputs this information to the FDD through the FD control circuit 3.
Transfer to 4.

As an example, it is assumed that the log medium 8 is mounted on the FDD 4. The FDD 4 tries to store the failure information in the designated cylinder position, but the log medium 8 fails in writing due to a write error. When the writing fails, the FD control circuit 3 detects it and requests the FD writing result storage circuit 6 to leave a “failure” result.

Further, the FD retry control circuit 5 constantly monitors the result stored in the FD write result storage circuit 6, and when detecting the storage of the "failure" result, the diagnostic processor 2 is replaced with the log medium 8. Issues a request and a command to retry writing. The diagnostic processor 2 that has received the replacement request displays “log medium defect / replacement” on the LED of the control panel 7 and instructs the operator to replace the log medium 8. When the operator replaces the normal log medium 9 according to the display, the FD control circuit 3 detects it and the diagnostic processor 2 resets the replacement request, so the display is reduced and the FD control circuit 3 displays the log medium replacement attention. To the diagnostic processor 2.

The diagnostic processor 2 which has received the log medium exchange attention receives the above-mentioned write retry command from the FD retry control circuit 5 and A of the log medium exchange attention.
The ND condition is checked, and the diagnostic processor 2 is triggered by the coincidence.
The failure information stored in the RAM (failed to write) is again transferred to the FDD 4 via the FD control circuit 3. Since the normal log medium 9 is inserted in the FDD 4, the failure information is stored in the log medium. Once stored,
The FD control circuit 3 determines whether the storage result (normal) is the diagnostic processor 2
Return to and cancel the write retry command.

In another case, if the FD other than the log medium is mounted instead of the log medium 8 in which the writing is not successful, the FD control circuit 3 uses the file name written in the header portion of the FD as the FD. Recognizing the difference, the diagnostic processor 2 displays "Log medium fraud / replacement" on the LED of the control panel 7.

Further, when the log medium is not mounted, "log medium not mounted / mounted" is displayed on the LED of the control panel 7.

In these cases, the operation after the display on the LED is the same as the operation in the above-mentioned embodiment.

[0018]

According to the present invention, the log medium storage "failure"
The result of the above is constantly monitored, and when it is a "failure", the operator is requested to replace the medium with a normal medium and the write retry process is performed. Even when the storage on the medium fails, the failure information can be surely left on the log medium by repeating the rewriting after inserting another log medium.
