Abstract

PURPOSE:To display error log information on a peripheral device even in case of a system shutdown by logging the error log information on the peripheral device in a log file on an incorporated system disk and also in a log file on a magnetic disk under the control of a service processor. CONSTITUTION:A fault information gathering means 31 generates the error log information based upon error information reported from an OS 3, records it in the error log file secured on a magnetic disk device 4, and also decides whether the error information is an error to be logged by the service processor 6; when the error information indicates the object error, the error log information is reported to a log request means 32. The log request means 32 sends a log request message to the service processor 6 together with the added error log information. The service processor 6 records the error log information in the log file secured on a magnetic disk device 8 under the control of the service processor. Consequently, the fault information on the peripheral device can be displayed at the time of the system shutdown.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a failure information collection method for peripheral devices, and more particularly to a failure information collection method that enables failure recovery when a system goes down.

[Conventional technology]

Conventionally, the occurrence of a failure in a peripheral device of this type of information processing system is detected by the operating system (hereinafter referred to as O8), and failure information is stored in the system resident disk (hereinafter referred to as 5RV).
) was logged.

Therefore, failure information was also displayed using a display utility or the like executed under O8.

[Problem to be solved by the invention]

The conventional peripheral device fault information collection method described above assumes that everything including the display function is under O8 operation, so there is no means to refer to peripheral device fault information when the system goes down.

[Means to solve the problem]

The configuration of the failure information collection method of the present invention includes a central processing unit,
In an information processing system consisting of a plurality of peripheral devices and a service processor, the central processing unit includes a fault information collection unit that detects a fault in the peripheral device and stores the fault information, and a fault information collection unit that detects a fault in the peripheral device and stores the fault information. log requesting means for requesting a service processor to record the failure information; A feature of the present invention is that even if the device becomes inoperable, the service processor can refer to the failure information of the peripheral device.

〔Example〕

Next, the failure information collection method of the present invention will be explained with reference to the drawings.

FIG. 1 is a system block diagram of an information processing system showing one embodiment of the present invention.

In FIG. 1, this information processing system includes a central processing unit 2, a plurality of peripheral devices (not shown) connected to the central processing unit 2, and one of the peripheral devices, in particular, a magnetic disk that stores system resident files. It consists of a device 4, a service processor 6 connected to the central processing unit 2, and a magnetic disk device 8 connected to the service processor 6.

An operating system 3 is running on the central processing unit 2, and processes tasks while executing input/output operations for the peripheral devices (not shown).

In the information processing system configured as above,
When S3 detects a failure in the peripheral device waiting to execute an input/output operation to the peripheral device, it performs a retry operation and notifies the failure information collection means 31 of the result after the retry is completed. The failure information collection means 31 generates error log information based on the error information notified from S3, records it in an error log file secured in the magnetic disk device 4, and also records the error information in the service processor 6. It is determined whether or not it is a log target error, and if it is a target error, error log information is notified to the log requesting means 32.

When the log requesting means 32 receives the error log information, the log requesting means 32 adds the error log information to a log recording request message and transmits the message to the service processor 6.

When the service processor 6 receives the log recording request message, the log recording means 61 records the error log information in a log file secured in the subordinate magnetic disk device 8.

〔Effect of the invention〕

As explained above, the present invention allows error log information of peripheral devices to be logged in a log file on the system resident disk, and if necessary, also in a log file on a magnetic disk under the service processor. This has the effect that even if the operating system is inoperable due to a system failure or the like, the service processor can display error log information of peripheral devices.

Claims (1)

[Claims] In an information processing system consisting of a central processing unit, a plurality of peripheral devices, and a service processor, the central processing unit includes a failure information collection means for detecting failures in peripheral devices and storing failure information; a log requesting means for requesting a service processor to record the stored failure information, and the service processor has a log recording means for recording the failure information in a subordinate external storage device in accordance with a log request instruction from a central processing unit. 1. A failure information collection method, characterized in that even if a central processing unit becomes inoperable, a service processor can refer to failure information of peripheral devices.
