Abstract

PURPOSE:To realize quick preventive maintenance by giving automatically information to a remote control maintenance center from a maintenance diagnosing device in case an information processor has an automatically correctable intermittent fault and the number of said faults exceeds a reference level for decision set previously in the same area. CONSTITUTION:A fault number comparing means 24 compares the number of faults occurred in the same area and registered in a memory means 22 with a reference level for decision set previously. If the number of said faults exceeds the reference level, this fact is informed to a remote maintenance center. In other words, the number of intermittent faults which are frequently produced in the same area of an information processor 1 exceeds the reference level, this fact is detected by the means 24 and informed to a remote maintenance center 3 concurrently with occurrence of a fixed fault. Thus the center 3 can quickly know the frequent occurrence of the intermittent faults.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a maintenance diagnosis device that enables maintenance diagnosis of an information processing device from a remote maintenance center via a line.
In particular, the present invention relates to an improvement in an automatic failure reporting method from a maintenance diagnosis device to a remote maintenance center when a failure occurs in an information processing device.

[Conventional technology]

2. Description of the Related Art If a failure occurs in a device constituting an information processing device and the device or system becomes unusable, it is necessary to quickly restore the device or system. Furthermore, even if a fault that has occurred is automatically repaired by the automatic correction function of the information processing device, it is necessary to save fault information regarding the fault that has occurred for future preventive maintenance. For this reason, conventionally, maintenance diagnostic equipment has been connected to information processing equipment, which has the function of communicating with a remote maintenance center via a line and also has the function of controlling operation in the event of a failure in the information processing equipment. However, when a failure occurs in an information processing device, a maintenance diagnostic device collects and analyzes failure information from the information processing device, and identifies failures that cannot be recovered from, that is, uncorrectable failures, and may cause some devices or systems to go down. In the event of a major failure (hereinafter referred to as a fixed failure), the failure information is stored in the storage means, and a notification is sent to the remote maintenance center via the line to enable quick recovery. In the case of a failure (hereinafter referred to as an intermittent failure) that allows processing to continue due to the automatic correction function, such as an intermittent failure (intermittent failure), the failure information and the number of failures at the same location are recorded for future preventive maintenance. The information is stored in the storage means.

At the remote maintenance center, it is possible to quickly respond to fixed failures by receiving reports, and preventive maintenance can be carried out by checking the failure information about intermittent failures stored in the storage means and the number of failures at the same location during regular maintenance. It becomes possible.

[Problem that the invention seeks to solve]

By the way, even if it is an intermittent disorder, if it occurs frequently,
This can develop into a serious fixed failure, and in the worst case scenario, it can lead to system failure. Therefore, it is necessary to know about such situations as soon as possible, but since intermittent failures were not reported in the past, remote maintenance centers often overlooked the fact until the next scheduled maintenance. Therefore, there is a drawback that there is a high risk of developing into a fixed failure and causing a system failure.

SUMMARY OF THE INVENTION An object of the present invention is to enable a remote maintenance center to quickly detect frequent occurrences of intermittent failures.

[Means for solving problems]

In order to achieve the above object, the present invention collects and analyzes fault information from the information processing device when a fault occurs in the information processing device, and stores the fault information when the fault information is related to a fixed fault. A maintenance diagnostic device that stores information in a means and sends a report to a remote maintenance center via a line, and when the fault information relates to an intermittent fault, registers the fault information and the number of faults at the same location in the storage means, Comparing means is provided for comparing the number of failures at the same location registered in the storage means with a preset determination reference number, and as a result of the comparison by the comparison means, the number of failures at the same location exceeds the determination reference number. When it exceeds the limit, a notification is sent to the remote maintenance center.

[Effect]

If intermittent failures occur frequently at the same location in the information processing equipment and the number of intermittent failures at the same location exceeds the criterion number, this will be detected by the comparison means and a notification will be sent to the remote maintenance center in the same way as when a fixed failure occurs. It will be done.

〔Example〕

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

FIG. 1 is a block diagram showing an example of an information processing system to which the automatic failure notification system of the present invention is applied, and includes an information processing device L consisting of an arithmetic processing unit, a main storage device, etc., and a The maintenance diagnosis device 2 is also connected to a remote maintenance center 3 via a line 4. The maintenance diagnosis device 2 includes a failure information collection means 21. Storage means 22.
Fault information registration means 23. Means for comparing number of failures 24. The storage means 22 includes an automatic notification means 25 and a fixed fault information section 22.
0, an intermittent failure information section 2219 and an intermittent failure number section 222 are included.

FIG. 2 is a flowchart of an example of processing by the fault information collection means 21;
Figure 4 is a flowchart of an example of processing by the fault information registration means 23, Figure 4 is a flowchart of an example of processing by the failure number comparison means 24, and Figure 5 is a flowchart of an example of processing by the automatic notification means 25. Please refer to each figure below. The operation of this embodiment will now be explained.

When a fault occurs in the information processing device 1 and the maintenance diagnostic device 2 is notified of this, the fault information collection means 21 reads fault information regarding the current fault from the information processing device 1 as shown in FIG. 211), and activates the failure information registration means 23 (212).

When the fault information registration means 23 is activated, as shown in FIG. 3, it analyzes the current fault information read by the fault information collection means 21 and determines whether the fault information is a fixed fault or an intermittent fault. For example, it is determined based on whether or not there is a description of automatic correction in the fault information (230), and if the fault is a fixed fault, the current fault information is registered in the fixed fault information section 220 of the storage means 22 (234), and the automatic notification means 25 (235), and the automatic notification means 25 responds to this by automatically dialing the line 4 as shown in FIG.
251), and sends a report to the remote maintenance center 3 including, for example, the occurrence of a fixed fault and information on the location of the fault (252).

On the other hand, if the current failure is an intermittent failure, the failure information registration means 23 registers the failure information in the intermittent failure information section 221 of the storage means 22 (231), and then calculates the number of failures related to the failure location identified from the failure information. Add 1 (23
2) When adding the number of failures, for example, if the number of failures corresponding to the failure point identified by the current failure information is not in the intermittent failure number section 222, the failure number storage area corresponding to the current failure point is added to the number of intermittent failures. 222 and set its content to "1", and if it already exists, increase the number of failures in that area.
1. Then, the failure information registration means 23 activates the failure number comparison means 24 (233).

When the failure number comparison means 24 is activated, as shown in FIG. The number N of failures is compared with the preset determination standard number N may (242), and if N≦N ax, the process ends.

However, N>Na+ax, that is, the number of judgment criteria at the same location N
When intermittent failures occur frequently enough to exceed IIIax, the automatic notification means 25 is activated (243). When activated, the automatic notification means 25 disconnects the line by automatic dialing processing etc. as shown in FIG. The remote maintenance center 3 is connected to the remote maintenance center 3 via 4 (251), and a report containing, for example, information indicating that intermittent failures have occurred frequently and failure location information is issued (252).

The remote maintenance center 3 can learn from the above notification that intermittent failures are occurring frequently in the information processing device 1, and therefore performs remote maintenance of the information processing device 1 using a known function in the maintenance diagnosis device 2. By starting, preventive maintenance can be carried out promptly.

〔Effect of the invention〕

As explained above, the present invention enables automatic correction of intermittent faults that occur in information processing equipment, and when the number of faults exceeds a predetermined criterion number at the same location, the maintenance diagnostic equipment sends information to a remote maintenance center. Since notifications are automatically issued, the remote maintenance center can quickly become aware of frequent occurrences of intermittent failures that were conventionally often overlooked until the next periodic maintenance because they were automatically corrected. Therefore, prompt preventive maintenance can be performed, and a situation where an intermittent failure develops into a serious fixed failure and the system goes down can be prevented.
