Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repair confirmation method after a maintenance operation for confirming a result of a maintenance operation performed before a failure occurs in an information processing apparatus. In many information processing devices, prevent the occurrence of failures, periodically check the operation to maintain the functions of the devices, and find the deteriorated or abnormal places early and take appropriate measures such as replacement. Maintenance is employed. Here, the concept of preventive maintenance of the equipment is that the test program is executed at the time of periodic maintenance, and if there is an abnormal part, the abnormal part is repaired, and the test program is executed again to confirm the repair. Although a preventive maintenance program has been started at the time of maintenance and progress has been made to a method of pointing out an abnormal point, in this preventive maintenance, it is necessary to confirm the result of the repair work performed in the preventive maintenance work.

[0002]

2. Description of the Related Art Conventionally, when starting, cleaning, adjusting, or replacing parts in a preventive maintenance program during a preventive maintenance operation, the preventive maintenance program is manually terminated, and a test program is executed again to execute a suspected test. Check the repair of the part.

[0003]

However, since the test program is intended to check a series of operations of the whole device under test and is not usually designed to test only a specific test item, It is difficult to surely confirm the repair of the location. Further, in the case of using a test program, an excessive test for confirming all items other than the suspected portion is required, so that extra test time is required.

In the conventional preventive maintenance, a preventive maintenance program is started, an abnormal part is repaired, the preventive maintenance program is terminated,
Since the repair confirmation is performed by an operation such as starting the test program, it takes too much maintenance time.

[0005] Further, the work completion report output by the preventive maintenance program merely describes the work location and does not describe what work has been performed. The result of the repair confirmation work cannot be confirmed. An object of the present invention is to provide a repair confirmation method after a maintenance operation in an information processing apparatus, in which a result confirmation after a maintenance operation can be performed easily and in a short time, and a work completion report specifying contents of the repair confirmation operation can be created. Is to do.
