Here, in the present specification, the maintenance target device and the like refer to a device (hereinafter, referred to as “maintenance target device”) and its components to be maintained by a person who performs maintenance. Here, there is often a physical cause for an abnormality to occur in a component. The cause is, for example, deterioration of electrical wiring, a recording portion or a driving portion of a recording device, and the like. Then, these deteriorations progress with the passage of time, the influence of these abnormalities becomes large, and eventually, due to the occurrence of multiple failures that cannot be recovered, the above switching cannot recover. In this situation, there is a possibility that all or a large part of the equipment to be maintained cannot be used, and the damage is great. Therefore, before such a situation occurs, it is important to determine the replacement time of the component parts from the abnormal situation of the equipment to be maintained and to replace them in advance.

Here, a computer system can be considered as a typical maintenance target device. The number of computer devices that make up a computer system generally increases year by year. The types of parts that make up these devices are diverse, and even if they are the same component, their reliability is not necessarily the same, depending on the development time, manufacturing time, or if there are multiple parts providing vendors, the providing vendors, etc. There are variations. Therefore, there is a problem that parts cannot be replaced at a uniform replacement time.

There are the following disclosures regarding solutions to problems related to this problem.

Patent Document 1 describes an array disk in which error information of a disk that is a component of a computer system is acquired, recorded in a specific file, and the error information is statistically analyzed to preventive replacement with a spare disk before a failure occurs. The automatic recovery method and system are disclosed.

Further, Patent Document 2 discloses a maintenance management system, a maintenance management device, a maintenance management method, and a maintenance management program for an array disk group, which are elements of a computer system. That is, log information is acquired from a plurality of disk devices, information on the number of failed array disks (fault number information) is acquired from the log information, and an abnormality rate for each generation of array disks is acquired based on the fault number information. Is calculated. Then, based on the calculated abnormality rate for each generation of the array disk, the above-mentioned predetermined allowable value for the number of occurrences of the recovery error of the array disk of each generation is updated. When the number of occurrences of the recovery error of the array disk exceeds the predetermined allowable value, the data in the array disk is copied to the spare array disk, and the array disk is replaced proactively.

[Maintenance management system configuration]
FIG. 2 is a conceptual diagram showing the configuration of the maintenance management system of the second embodiment.
The maintenance management system of the present embodiment includes a maintenance device 120 and a management device 1320.

The maintenance device 120 is installed at the customer site 020. The maintenance device 120 includes a maintenance network 320, a log information receiving unit 1720, a maintenance device information processing unit 1220, a maintenance device allowable value recording unit 220, and a maintenance device transmission / reception unit 1120.

The maintenance network 320 is an information communication means, and has a function of enabling information to be transmitted from the maintenance target device 4200 to the maintenance device information processing unit 1220. The maintenance network 320 may be omitted when a substitute network is available.

The log information receiving unit 1720 receives the log information of the maintenance element sent from the maintenance target device 4200 through the maintenance network 320, and sends it to the maintenance device information processing unit 1220.

The maintenance device information processing unit 1220 processes log information of maintenance elements (meaning components to be maintained in the maintenance target device; the same applies hereinafter) of the maintenance target device 4200 sent from the maintenance target device 4200 through the maintenance network 320. Then, the log information is sent to the maintenance device transmission / reception unit 1120. The log information at this time includes information regarding the occurrence of an abnormality in the maintenance element of the maintenance target device 4200. The maintenance device information processing unit 1220 further processes the information sent from the maintenance device transmission / reception unit 1120 including the error occurrence number allowable value described below, and sends the information to the maintenance device allowable value recording unit 220.

The maintenance device allowable value recording unit 220 records the allowable value of the number of times of abnormality occurrence.

The maintenance target device 4200 is typically a computer or a computer-related device.

Here, the permissible value of the number of occurrences of abnormality refers to the number of occurrences of abnormality for the maintenance element, which indicates an index for replacing or repairing the maintenance element (excluding so-called recovery in which the maintenance target device repairs the abnormality by itself). In this case, the number of occurrences of an abnormality may be the number of times the maintenance element has been activated or the number of times within a predetermined period.

Here, the "abnormality" of the maintenance element is an abnormality that can restore the function without replacing or repairing the maintenance target device, etc., and the maintenance target device, etc. is replaced due to the occurrence of the abnormality. It may be counted including necessary abnormalities. In addition, it may be counted including abnormalities that do not require recovery.

The maintenance device transmission / reception unit 1120 receives the log information sent from the maintenance device information processing unit 1220 and transmits it to the management device transmission / reception unit 720 of the management device 1320 via the general-purpose communication line 620.

It includes an output unit 1620.

The management device transmission / reception unit 720 receives the log information sent from the maintenance device transmission / reception unit 1120 via the general-purpose communication line 620, and sends the log information to the log information recording unit 520. Further, the permissible value for the number of times of abnormality occurrence after the update sent from the permissible value update unit 920 is sent to the maintenance device transmission / reception unit 1120 of the maintenance device 120.

The log information recording unit 520 receives and records the log information sent from the management device transmission / reception unit 720. The log information is sent to the abnormality analysis unit 1420.

The abnormality analysis unit 1420 analyzes the log information and detects an abnormality in the maintenance element. Information regarding the abnormality of the maintenance element is sent to the abnormality rate calculation unit 820, and the abnormality rate for the maintenance element is calculated. The calculated abnormality rate is sent to the permissible value update unit 920. Here, the abnormality rate is the number of times that one maintenance factor causes an abnormality within a predetermined period of time or is estimated to generate an abnormality. For example, as the abnormality rate, the number of abnormalities that have occurred from the operation of the maintenance element to a certain point in time can be estimated by dividing by the operation time and multiplying by a certain period. As the abnormality rate, for example, the annual average abnormality rate that occurs in one year for a certain part or the like can be used.

The permissible value update unit 920 is based on the abnormality rate of a certain maintenance element sent from the abnormality rate calculation unit 820 and the previous permissible number of occurrences of an abnormality for the maintenance element sent from the management device tolerance value recording unit 1020. , Calculate the permissible value of the number of abnormal occurrences after updating. The permissible value of the number of abnormal occurrences after the update is sent to the management device permissible value recording unit 1020 and the management device transmission / reception unit 720.

The management device permissible value recording unit 1020 records the permissible value of the number of abnormal occurrences after the update sent from the permissible value updating unit 920. Further, the allowable value update unit 920 is sent to the allowable value update unit 920, which is the previous allowable value for the number of abnormal occurrences used when the allowable value update unit 920 calculates the allowable value after the update. Further, a preset abnormality rate threshold value is recorded, and the abnormality rate threshold value used by the permissible value updating unit 920 for calculating the renewed permissible value is sent to the permissible value updating unit 920.

Here, the abnormality rate threshold value refers to an allowable value of the abnormality rate applied to each of the maintenance element groups as an index indicating whether or not a plurality of maintenance elements should be exchanged on average as the group. The method of determining this abnormal rate threshold value is arbitrary. It may be determined in consideration of the average of the actual abnormal occurrence rates of individual maintenance factors, or it may be determined simply based on actual results.

The abnormality rate threshold value may be recorded not in the management device allowable value recording unit 1020 but in another recordable portion, and may be taken out as needed.

The management device output unit 1620 outputs information including an updated error occurrence count allowable value for the maintenance element of the maintenance target device 4010 and an actual error occurrence count for the maintenance element. The output here is typically a display on the display unit, but an output by another method such as voice may be used. The person performing maintenance knows that the maintenance element should be replaced based on the output information. Alternatively, it becomes possible to predict how much time can be left before the replacement. If the number of times an abnormality actually occurs is close to the permissible value of the number of times of abnormality occurrence, the maintenance element is about to be replaced.
[Maintenance management method]
FIG. 3 is a flowchart showing the maintenance management method of the second embodiment.

The log information of the maintenance element of the maintenance target device 4200 is sent and received to the log information receiving unit 1720 through the maintenance network 320, and is sent to the maintenance device information processing unit 1220.

Send log information (S202). Then, the management device transmission / reception unit 720 receives the log information and sends the log information to the log information recording unit 520 (S203). The log information recording unit 520 records the log information and sends the log information to the abnormality analysis unit 1420 (S204). The abnormality analysis unit 1420 analyzes the sent log information, extracts information regarding the occurrence of an abnormality, and sends it to the abnormality rate calculation unit 820 (S205). The abnormality rate calculation unit 820 analyzes the received log information, extracts the abnormality information of the maintenance element of the maintenance target device 4200, calculates the abnormality rate, and sends the calculated abnormality rate to the allowable value update unit 920 (S206). ). The permissible value update unit 920 determines whether the sent abnormality rate is smaller than the abnormality rate threshold value (S207). When the abnormality rate is smaller than the abnormality rate threshold value, the permissible value for the number of occurrences of abnormality is increased by 1 (S208). When the abnormality rate is not smaller than the abnormality rate threshold value, it is determined whether the abnormality rate is larger than the abnormality rate threshold value (S209). When the abnormality rate is larger than the abnormality rate threshold value, the permissible value for the number of occurrences of abnormality is reduced by one (S210). If the abnormality rate is not larger than the abnormality rate threshold value, the permissible value for the number of occurrences of abnormality is not updated (S211). Next, when the permissible number of abnormal occurrences is updated in S208 or S210, the permissible number of abnormal occurrences after the update is sent to the management device permissible value recording unit 1020, and the management device permissible value recording unit 1020 receives the updated abnormality. Record the permissible number of occurrences (S212). Then, the management device output unit 1620 outputs the permissible value of the number of times of abnormality occurrence after the update (S213). The permissible value of the number of times of abnormality occurrence after the update is sent to the management device transmission / reception unit 720, and is transmitted to the maintenance device transmission / reception unit 1120 of the maintenance device 120 via a general-purpose communication line (S214). The updated error occurrence count allowable value received by the maintenance device transmission / reception unit 1120 is recorded by the maintenance device allowable value recording unit 220.
[Effect of this embodiment]
As described above, the maintenance management system of the present embodiment updates the permissible number of abnormal occurrences, which is an index indicating that the number of abnormal occurrences for which the maintenance element should be replaced has been reached from the abnormality rate of each maintenance element. To do. Therefore, even if the reliability of the maintenance element differs depending on the supplier, the manufacturing time, the manufacturing lot, etc., the maintenance manager can predict the optimum replacement timing peculiar to each maintenance element. It will be possible.

The abnormality analysis unit 1440 analyzes the log information, extracts information on the abnormality of the maintenance element of the maintenance target devices 4411 to 4418, and sends the information to the abnormality rate calculation unit 840 (S408). The abnormality rate calculation unit 840 extracts the received information on the abnormality, calculates the abnormality rate, and sends the abnormality rate to the permissible value update unit 940 (S409). The permissible value update unit 940 determines whether the sent abnormality rate is smaller than the preset abnormality rate threshold value (S410). When the abnormality rate is smaller than the abnormality rate threshold value, the permissible value for the number of occurrences of abnormality is increased by 1 (S411). When the abnormality rate is not smaller than the abnormality rate threshold value, it is determined whether the abnormality rate is larger than the abnormality rate threshold value (S412). When the abnormality rate is larger than the abnormality rate threshold value, the permissible value for the number of occurrences of abnormality is reduced by one (S413). If the abnormality rate is not larger than the abnormality rate threshold value, the permissible value for the number of occurrences of abnormality is not updated (S414). Next, when the permissible number of abnormal occurrences is updated in S411 or S413, the permissible number of abnormal occurrences after the update is sent to the management device permissible value recording unit 1040, and the management device permissible value recording unit 1040 receives the updated abnormality. Record the permissible number of occurrences (S415). The management device input / output unit 1540 outputs the permissible value of the number of abnormal occurrences after the update (S416). The output in this case is typically a display on the display unit, but may be another method such as an audio output. Next, it is determined whether or not the first maintenance device transmission / reception unit 1141 is connected to the management device transmission / reception unit 740 through the general-purpose communication line 640 (S417). When the general-purpose communication line 640 is the Internet, this determination can be made by its function. When the first maintenance device transmission / reception unit 1141 is connected to the management device transmission / reception unit 740 through the general-purpose communication line 640, the permissible value of the number of occurrences of abnormalities after the update is transmitted to the first maintenance device transmission / reception unit 1141 of the maintenance device ( S418). When the first maintenance device transmission / reception unit 1141 is not connected to the management device transmission / reception unit 740 through the general-purpose communication line 640, the permissible value of the number of abnormal occurrences after the update is input from the first maintenance device input / output unit 2041 (S419). ). The permissible value of the number of times of abnormality occurrence after the update is recorded in the first maintenance device permissible value recording unit 241 (S420).
