Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote diagnostic maintenance system, method, and program, and more particularly, to a remote diagnostic maintenance system, method for deciding a maintenance action based on an error rate set for each device constituting a computer system. , And about the program.

[0002]

2. Description of the Related Art In a current computer system, a retry function is installed in each device in order to prevent the system from being stopped when a failure occurs and not to hinder the operation. That is, the retry function enables the system operation to be continued.

However, even if the system stop is remedied by the retry function, the device must be replaced depending on the number of retries and the contents of the failure. The criterion for replacement exists for each device. The criterion, that is, the threshold value can be set in the OS and the diagnostic device.

Conventionally, the method of setting the threshold value is not clear, and a fixed value is often used for a long period of time without being managed. That is, the standard varies depending on the shipping time of the device and the element used, and therefore the operator must individually judge whether or not to replace the device.

[0005]

As described above, in the conventional system maintenance management using the retry function, the criteria for determining the failure treatment are ambiguous, and in the end, each system is in charge of maintenance. There is a problem that it is necessary to make an individual judgment based on the experience and intuition of the worker.

An object of the present invention is to improve the above-mentioned drawbacks by setting a threshold value which is a criterion for judging a failure on the basis of the theoretical value of the failure predicted to occur and its actual value. It is to provide a remote diagnostic maintenance method, method, and program that can perform appropriate preventive maintenance in a variable manner.

FIGS. 3, 4 and 5 are flow charts showing the operation of the above remote diagnostic maintenance system. Next, the operation of the present invention will be described with reference to these drawings.

First, the computer system 100 stores the fault information of the fault that has occurred in the error log file 13 of the maintenance processor (step A1). Then, the stored fault data is transmitted to the remote center system 200 via the communication line (step A2).

The remote center system 200 stores the received notification data in the failure history data file 1 via the failure receiving section 5 (steps A3 and A4). And
The remote center system 200 refers to the failure history data file 1 at a determined cycle and calculates the failure occurrence rate for each device for a certain period (step A5).

The remote center system 200 is
Based on the theoretical failure rate at the time of developing the apparatus, the design failure rate data file 3 accumulating the failure rate data for each apparatus is created (steps A6 and A7).

Next, the remote center system 200
The actual failure occurrence rate and the theoretical failure rate are compared in a determined cycle, and a numerical value with a high occurrence frequency is stored in the error rate master file 4 for each device as the actual error rate of the arithmetic operation system device 8 and the input / output system device 9. (Steps A8 and A9).

Next, the remote center system 200
Error rate master file 4 and user device configuration data file 2 for each device stored in a determined cycle
Based on the above, the actual error rate of each of the arithmetic operation system device 8 and the input / output system device 9 of the computer system 100 is extracted (step B1). Then, the extracted actual error rate for each user is transmitted to the maintenance processor 6 of the computer system 100 (step B2).

The maintenance processor 6 stores the received actual error rate of each of the arithmetic system device 8 and the input / output system device 9 in the system error rate table 14 (step B3).

Further, the maintenance processor 6 transmits the actual error rate of the arithmetic unit 8 from the system error rate table 14 to the diagnostic processor 7 when the computer system 100 is started up, and the diagnostic processor 7 sends it to the arithmetic unit error. Stored in the rate table 15 and managed.
At the same time, the maintenance processor 6 transmits the actual error rate of the input / output system device 9 to the OS 12, and the OS 12 stores and manages it in the input / output system device error rate table 16 (steps B4 and B5).

When a failure occurs in the computer system 100 after storing the actual error rate, the diagnostic processor 7 and the OS 12 refer to the actual error rate to determine whether the failure is equal to or more than the error rate or less than the error rate, that is, the failure occurrence for the reference time. It is checked whether the allowable number of times is exceeded (steps C1 and C2).

Then, the diagnostic processor 7 and the OS 12
Adds a comment to the effect that replacement is necessary if the error rate is exceeded, and sends fault information to the maintenance processor 6 (step C3). If the error rate is less than the error rate, a comment that no action is required is added and the failure information is transmitted to the maintenance processor 6 (step C4).

The maintenance processor 6 sends the fault information and the comment to the remote center system 20 regardless of whether the fault is equal to or higher than the error rate or lower than the error rate.
0, and the failure information is stored in the error log file 13 (step C5).

In the remote center system 200, the failure treatment is judged based on the received failure information and comment (step C6).

The remote diagnostic maintenance system described above operates by executing a program stored in each main memory (not shown) of the computer system 100 and the remote center system 200. This program is normally stored in a secondary storage such as a hard disk, and is loaded and executed in the main storage during system operation.

[0044]

As described above in detail, according to the present invention, the error rate regularly reviewed based on the design failure rate and the actual failure occurrence rate assumed at the time of designing the device can be used for the failure treatment. Since the judgment criteria are incorporated, there is an effect that the preventive maintenance of the computer system can be accurately performed without depending on the experience and intuition of the person in charge of maintenance.
