Abstract

PURPOSE:To discriminate between unsettled fault information and settled fault information and facilitate maintaining operation by substituting suspected fault article name/information name information corresponding to the fault which is already settled with a repair end message. CONSTITUTION:In a step S10, whether repair is performed with suspected component name information outputted by a log editing means is inquired after repair is performed with suspected fault component name information which is edited and outputted by the log editing means. In a step S11, the suspected component name information obtained by a reference suspected component name information inquiring means is replaced with the repair end message.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fault diagnosis result display method for a logical device, and more particularly to a fault diagnosis result display method in which a service processor diagnoses a fault in a logic device constituting an information processing system.

0002

2. Description of the Related Art Conventionally, as an example of this type of failure diagnosis result display method, a built-in diagnosis method (Built-in Di
agnostics (hereinafter referred to as BID method).

[0003] In this BID method, various hardware error detection circuits are installed at important points in logic devices such as arithmetic processing units, input/output control units, and main storage devices that make up an information processing system. When the detection circuit detects an error, an error indicator flip-flop provided corresponding to the error detection circuit is collected as an error log by the service processor in the information processing system via the diagnosis unit and written to the magnetic disk device. The collected error logs are called from the magnetic disk device as needed, and the service processor performs failure diagnosis. This failure diagnosis analysis is carried out using the collected error log as a failure symptom, and the suspected failure component name information obtained through this failure diagnosis analysis is written into an error log file of a magnetic disk device or the like. The suspected failure component name information written in the error log file is read out from the log file as necessary, edited and output together with the error log.

[Problem to be Solved by the Invention] However, in the conventional fault diagnosis result display method for logical devices, even after the repair is completed according to the fault diagnosis result, the suspected faulty product name information is displayed in the same way as before the repair. However, there was a problem in that it was difficult to distinguish between a problem that had already been resolved and a problem that had newly occurred.

[0005]

[Means for Solving the Problems] The present invention provides a service processor having a maintenance diagnosis function, an error detection circuit provided at key points of a logic device, and an error detection circuit provided corresponding to each error detection circuit. An error indicator flip-flop that is set when a circuit detects an error in the logic device, and an error log that includes the contents held in the error indicator flip-flop in the logic device when a failure occurs in the logic device are passed through a diagnostic path. a log collection means that collects the error log into an error log file in the service processor through the service processor, and performs a fault diagnosis analysis using the error log collected by the log collection means as a failure symptom, points out the suspected fault component name information, and identifies the suspected fault. A log analysis means for recording part name information in the error log file, and a log editing means for editing and outputting the error log and the corresponding suspected failure part name information obtained by the log collection means and the log analysis means. In a method for displaying failure diagnosis results of an information processing device, after a repair is performed using suspected faulty part name information edited and output by the log editing means, which suspected faulty part name information output by the log editing means is used to carry out the repair. The present invention is characterized by comprising a reference suspect part name information inquiry means for inquiring about the reference suspect part name information, and a repair completion message setting means for replacing the suspect part name information obtained by the reference suspect part name information inquiry means with a repair completion message.

[Embodiment] FIG. 1 is a flowchart of processing in an embodiment of the fault diagnosis method of the present invention, and shows steps S1 to S13.
indicates each step. Further, FIG. 2 is a block diagram showing an example of an information processing system to which this embodiment is applied. It consists of a diagnostic unit 14 connected to an arithmetic processing unit 11, an input/output control unit 12, and a main storage device 13 via a path 19, a service processor 15, a magnetic disk device 16, a console 17, and a printer 18.

Further, as shown in FIG. 3, the magnetic disk device 16 includes a log collection program 31, a log analysis program 32, a log editing program 33, a suspect component name inquiry program 34, a repair completion message writing program 35, and a log information program. n items (361 to 36n) and repair completion message 37 are stored. As shown in FIG. 4, each log information stores log information 41 and suspected failure product name information 42.

Now, if any failure occurs in the information processing apparatus shown in FIG. 2, the service processor 15 is notified via the diagnostic unit 14 (step S1). Next, the service processor 15 starts the log collection program 31 (step S2). The log collection program 31 is
Log information is collected through the diagnostic unit and the log data is stored in the magnetic disk device 16.

Next, the service processor 15 starts the log analysis program 32 (step S3). The log analysis program 32 analyzes the log information 41, points out the suspected failed product name information, and writes the suspected failed product name information in the log information (step S4).

Next, the log editing program 33 is manually created.
is activated (step S5), and the log information 41 and suspected malfunction product name information 42 are edited and output to the console 17 or printer 18 (step S6). Repair work is performed according to the suspected malfunction product name information 42 (step S7), and the repair is completed (step S8).

[0011] The reference suspected failure product name information name information inquiry means 34 is activated manually (step S9), and the log information number referred to during repair is inquired (step S9).
10). Next, the suspected failure product name information area of the corresponding log information entry is replaced with the repair completed message 37 (step S11). For example, as shown in Figure 5, four logs have been collected, and the log information #

[0012] Thereafter, a request to output information on the name of the suspected malfunctioning product is made manually (step S12), and the log editing program 31 is started.
8 (step S13).

[0013]

[Effects of the Invention] As explained above, the present invention replaces the name information of the suspected faulty product name corresponding to the already solved fault with a repair completed message, so that the information on the unresolved fault and the resolved fault information can be changed. Since they can be distinguished, maintenance work is facilitated.
