Abstract

PURPOSE:To perform the storage of fault information and the extraction of log data by detecting a processor in which a fault occurs with a diagnostic processor when an unknown fault occurs in the processor. CONSTITUTION:When the unknown fault occurs in the processor 2, the processor 2 informs the occurrence of the fault to a fault information storage circuit 4, and the fault information storage circuit 4 informs the fault to the diagnostic processor 1, and also, reads out the fault information from the processor 2 in which the fault occurs. The fault information storage circuit 4, after sending the fault information from the processor 2 to the diagnostic processor 1, reads out calendar clock data from a calendar clock circuit 3, and stores the fault information. The fault information storage circuit 4 storing the fault information in such way transmits a long request to the processor 2 in which the fault occurs, and extracts the log data, and a log data storage circuit 5 receiving the log data stores the log data.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fault handling method for an information processing device, and in particular, when a fault occurs in a processor, the diagnostic processor does not read out the status information of each processor. The present invention relates to a fault handling method for an information processing device that can detect a processor in which a fault has occurred, store fault information, and collect log data.

[Conventional technology]

Conventionally, the fault handling method for this type of information processing equipment is that when a fault occurs in a processor, a diagnostic processor reads the status information of each processor, detects the faulty processor, and notifies the service processor of the fault. The method used was to store failure information and collect log data by requesting logs to the service processor. [Problems to be Solved by the Invention] In the conventional failure handling method of the information processing device described above, when some kind of failure occurs in a processor, a diagnostic processor reads the status information of each processor and detects the processor in which the failure has occurred. This method has the disadvantage that failure processing is slow because it stores failure information by notifying the service processor of failures and collects log data by requesting logs to the service processor. [Means for Solving the Problems] The fault handling method of the information processing device of the present invention is such that, when some fault occurs in a processor, a fault occurrence notification is sent to a diagnostic processor, and fault information from the faulty processor is received and stored. After that, a fault information storage circuit that reports the faulty processor and its fault information to the diagnostic processor, and a log data storage circuit that stores log data from the processor collected in response to a log request from the fault information storage circuit. have. [Example] Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention. FIG. 1 shows one diagnostic processor 1, a plurality of processors 2, a calendar clock circuit 3, and a fault information storage circuit 4.
The log data storage circuit 5 warns that this is the case.

When some kind of failure occurs in the processor 2, the processor 2 notifies the failure information storage circuit 4 of the occurrence of the failure.

The fault information storage circuit 4, which has received the fault occurrence notification from the processor 2, notifies the diagnostic processor 1 of the fault, and reads the fault information from the processor 2 where the fault has occurred.

The fault information storage circuit 4 which has received the fault information from the processor 2 transmits the fault information from the processor 2 to the diagnostic processor 1, reads calendar clock data from the calendar clock circuit 3, and stores the fault information. The fault information storage circuit 4 that has stored the fault information sends a log request to the processor 2 where the fault has occurred and collects log data. Processor 2, which received the log request,
Send log data to the fault information storage circuit 4. The fault information storage circuit 4 that has received the log data from the processor 2 transmits the received log data to the log data storage circuit 5. The log data storage circuit 5 that has received the log data from the fault information storage circuit 4 stores the received log data. When the log data collection is completed, the failure information storage circuit 4
notifies the diagnostic processor l that the log has ended. The diagnostic processor 1, which has received the log end notification from the fault information storage circuit 4, thereafter performs fault processing for the processor 2 in which the fault has occurred. [Effects of the Invention] As explained above, the present invention allows a diagnostic processor to detect a faulty processor without reading out the status information of each processor when a fault occurs in a processor, store fault information, and log data. This has the effect of allowing the collection of
