Abstract

PURPOSE:To reduce the application time of a communication circuit set between a maintenance diagnosing device and a maintenance center, by avoiding such a case where the same unrecovered fault information is sent to the maintenance center in many times. CONSTITUTION:When a fault occurs, a logical device 9-n gives the fault information to a log register means 4 via a maintenance diagnosis control means 2 of a maintenance diagnosing device 1. The means 4 writes the received fault information into a memory means 6 together with a flag showing an unrecovered state and starts an automatic reporting means 5. The means 5 transfers the latest fault information to a maintenance center 8 via a communication circuit 7 only when the unrecovered fault information having the same fault factor as the latest information is not included in the information stored in the means 6. While the means 5 processes the unrecovered fault information if detected. Therefore the fault information caused by the same factor are sent just once to the center 8 before they are recovered. As a result, the application time can be reduced for a communication circuit set between the device 1 and the center 8.

Description

[Detailed Description of the Invention] [Industrial Application Field] When a failure occurs in a logical device, the present invention collects failure information of the logical device and transfers the collected failure information to a maintenance center via a communication line. Regarding maintenance diagnostic equipment.

[Conventional technology]

In a computer system consisting of logical devices such as arithmetic processing units, main storage devices, and input/output processing units, when a failure occurs in the logical device that is subject to maintenance diagnosis, the failure information is collected and sent to a remote location. A maintenance diagnostic device that transfers the collected fault information to a maintenance center located in I am trying to transfer it to the maintenance center.

[Problem that the invention seeks to solve]

As mentioned above, when a failure occurs in a logical device, conventional maintenance diagnostic equipment unconditionally forwards all the collected failure information to the maintenance center. If this occurs, the same fault information will be transferred to the maintenance center many times. For this reason, there is a problem that the storage means for accumulating fault information in the maintenance center is wasted due to the same fault information, and the usage time of the communication line between the maintenance diagnosis device and the maintenance center is wasted. In addition, when other maintenance diagnostic devices connected to the maintenance center try to communicate with the maintenance center, there is a possibility that the communication line is in use. There was also a problem that there was a high possibility that communication would be impossible.

The present invention aims to solve the above problems by preventing the same failure information from being sent to a maintenance center many times.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a maintenance diagnosis device having a function of transmitting failure information of a logical device to a maintenance center via a communication line when a failure occurs in the logical device. Each time a failure occurrence of the logical device is detected,
maintenance diagnosis control means for reading fault information of the logical device; and each time the maintenance diagnosis control means reads fault information, the fault information read by the maintenance diagnosis control means and the fact that the cause of the fault has not been repaired; a log registration means for chronologically registering in a storage means repaired flags in association with repaired flags set with values indicating the repaired flags corresponding to specified failure information among the repaired flags stored in the storage means; repair information setting means for changing the value of the flag to a value indicating repaired; and each time the log registration means registers failure information and the repaired flag in the storage means, the log registration means registers the fault information and the repaired flag in the storage means. A search is performed to determine whether or not fault information exists that has the same fault cause as the latest fault information and whose corresponding repaired flag is set to a value indicating unrepaired, and only if it does not exist, sends the communication to the maintenance center. The system is equipped with an automatic reporting means for transmitting the latest failure information via a line. A search is performed to see if there is any fault information in the storage means that has the same fault cause as the fault information and the repaired flag indicates that it has not been repaired, and only if there is no fault information that satisfies the above conditions, the latest fault information is maintained. Send to center. Therefore, failure information due to the same cause before repair is transferred to the maintenance center only once.

〔Example〕

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

FIG. 1 is a block diagram of an embodiment of the invention.

The maintenance diagnosis device 1 includes a maintenance diagnosis control means 2, a repair information setting means 3, a log registration means 4, an automatic reporting means 5, and a storage means 6. The n logical devices 9-1 to 9-n, which are connected to the automatic reporting means 5 in the diagnostic apparatus 1 and are subject to maintenance diagnosis, are connected to the maintenance diagnosis control means 2 in the maintenance diagnosis apparatus 1.

2 is a flowchart showing the processing content of the repair information setting means 3, FIG. 3 is a flowchart showing the processing content of the log registration means 4, and FIG. 4 is a flowchart showing the processing content of the automatic reporting means 5. The operation shown in FIG. 1 will be explained with reference to FIGS. 2 to 4.

The maintenance diagnosis control means 2 in the maintenance diagnosis device 1 constantly detects whether a failure has occurred in the logical devices 9-1 to 9-n that are subject to maintenance diagnosis. Now, taking as an example the case where a failure occurs in the logical device 9-n, the operation shown in FIG. 1 will be explained as follows.
It will look like this:

When a failure occurs in the logical device 9-n, a failure report including the device type information is sent to the maintenance diagnosis control means 2, and the maintenance diagnosis control means 2 includes the device type information of the logical device 9-n in the log registration means 4. Add problem report. As a result, as shown in the flowchart of FIG. 3, the log registration means 4 first identifies the device type of the logical device 9-n that is the source of the failure based on the device type information (step 531), and then identifies the device type for each device type. A predetermined procedure for reading the internal information of the logical device is added to the maintenance diagnosis control means 2, and an instruction is given to read the internal information of the logical device t9-n (step 532).

As a result, the maintenance diagnosis control means 2 executes the logical device fft 9- according to the successive procedure added from the log registration means 4.
The internal information (fault information) of n is read out, and the read fault information is added to the log registration means 4.

The log registration means 4 connects the maintenance diagnosis control means 2 to the logical device 9-
When n fault information is added, a value indicating unrepaired is set to the repaired flag indicating whether the fault has been repaired or not, and then
Adding the repaired flag to the fault information of the logical device 9-n added from the maintenance diagnosis control means 2 (step 533);
Next, the failure information with the repaired flag added is stored in the storage means 6.
(step 534). At this time, log registration means 4
is to add the latest fault information to which the repaired flag has been added in step S33 to the end of the fault information already stored in the storage means 6. Therefore, each fault information stored in the storage means 6 is in chronological order. Then, when the above processing is completed, the log registration means 4 starts the automatic reporting means 5 (step 535).

When the automatic reporting means 5 is activated by the log registration means 4, as shown in the flowchart of FIG. 4, the automatic reporting means 5 first compares the latest fault information stored in the storage means 6 with other fault information. Faults that have the same cause as the latest fault information in chronological order of all the fault information stored in the storage means, and the repaired flag attached to the fault information is in an unrepaired state. This is repeated until the information is detected or the comparison with all fault information is completed (step 541). Note that fault information with the same fault cause as the latest fault information can be detected, for example, by searching for the same fault information as the latest fault information, or by searching for specific information in the fault information,
For example, error indicator flip-flop (EIF)
This is done by searching for failure information in which the value indicating the status of ) is equal to the value indicating the status of the error indicator flip-flop in the latest failure information. Then,
The automatic reporting means 5 determines whether information whose repaired flag is set to "unrepaired" in the latest fault information and fault information with the same fault cause is found in the search process in step 341 (step 542), or not found. If it is determined that the fault has been found, the latest fault information is transferred to the maintenance center 8 via the communication line 7 (step 543), and if it is determined that the fault has been found, the process is terminated.

The operation of the maintenance/diagnosis device 1 when a failure occurs in the logical device 9-n has been explained above.
The operation of the maintenance diagnosis device 1 when a fault in the maintenance diagnosis device 1 is repaired will be explained.

When the logical device 9-n is repaired, the repair information setting means 3 is activated by the operator. When activated, the repair information setting means 3 first instructs the operator about which fault information among the fault information stored in the storage means 6, as shown in the flowchart of FIG. An inquiry is made regarding the setting, and an instruction from the operator regarding the inquiry is received (step 521). In this case, inquiries to the operator are made by displaying an inquiry message on, for example, a CRT, and instructions from the operator are made by inputting a failure information number or the like using, for example, a keyboard.

Upon receiving instructions from the operator, the repair information setting means 3:
The fault information instructed by the operator is selected from the storage means 6 (step 522), and the repaired flag added to the selected fault information is changed to a value indicating repaired (step 523).

Furthermore, when the logical device 9-n is repaired, the operator
Among the fault information stored in the storage means 6, the repair completed flag corresponding to all fault information related to repair is changed by the repair information setting means 3 to a value indicating repair completed.

In this case, the operator needs to know which fault information among the fault information stored in the storage means 6 is the fault information related to the repair, but as in the past, the operator Since the contents of the storage means 6 are printed out and held as repair materials, it can be known from the contents of the printout.

〔Effect of the invention〕

As explained above, the present invention records fault information in a storage means together with a repaired flag indicating that the cause of the fault is unrepaired when a fault occurs in a logical device, and records the fault information in a storage means together with a repaired flag indicating that the cause of the fault is unrepaired. Fault information is transferred to the maintenance center only when there is no fault information with a value set to indicate unrepaired, and when the logical device is repaired, the value of the repaired flag in the fault information related to repair is transferred to the maintenance center. Since the error information is changed to repaired, failure information due to the same cause of failure before repair is transferred to the maintenance center only once. Therefore, this has the effect of preventing the storage means in the maintenance center that stores fault information from being wasted with the same fault information, and also eliminates the use of wasteful communication lines between the maintenance diagnosis device and the maintenance center. This has the effect of saving line usage charges, and furthermore, when other maintenance diagnostic devices connected to the maintenance center try to communicate with the maintenance center, the communication line is in use and communication is interrupted. It also has the effect of reducing the possibility of becoming disabled.
