Abstract

PURPOSE:To speed up trouble processing of each peripheral device and to maintain each device as a single body, by providing each peripheral device with a means which collects necessary trouble information, and edits and displays it when the trouble happened to the peripheral device. CONSTITUTION:When a check circuit detects trouble of an input/output device 3 or input/output controller 2, an input/output control mechanism 4 generates sense data by referring to operation environ information, etc. The data is stored in a buffer 5 and a timer calendar mechanism 7 reads data and time data on the trouble from a cpul. Then, the data and time data, physical number of the troubled device, and sense data are printed out on a printer 6 in hexadecimal notation (or decimal notation) and the contents of the buffer 5 are cleared.

Description

Detailed Description of the Invention (1) Technical Field of the Invention The present invention relates to a failure handling method in an information processing system, and in particular, when a failure occurs in an input/output device or an input/output control device, generated sense information (5 sense This invention relates to a system for outputting information (i.e. information) into the faulty device and providing full fault analysis means.

(2) Problems with conventional technology Conventionally, input/output devices (No.) and input/output control devices (No.
), when a failure occurs in Sl! ! cp as NSK information
Create transfer data to a, transfer it to the CPU, and
On the U side, it has been common practice to centrally record failure information in a failure accumulation file provided on a magnetic disk or the like, or to access all of the files and provide all failure analysis materials. In this conventional method, it is sufficient to establish a fault handling system for all devices, but in the case of an information processing system in which each device incorporates various devices, for example, from other manufacturers, a complete comprehensive fault handling system is required. However, there are many disadvantages in that it is not possible to create a system, and therefore troubleshooting problems in each device cannot be done quickly and appropriately.

(3) Purpose of the Invention The present invention ll''l: An object of the present invention is to provide a method that eliminates the above-mentioned drawbacks and makes it possible to sufficiently maintain the input/output device and input/output control device as individual units in an information processing system. .

(4) Structure of the Invention The object is to store necessary failure information when a failure occurs in a peripheral device in a system that sends failure information of peripheral devices to all central processing units for processing.

(5) Examples of the invention The present invention will be described in detail below using the drawings.

The figure is a block diagram showing one embodiment of the present invention.

In the figure, l is a central processing unit (CPU), 2 is an input/output control device (IOC), 3 is an input/output device, 4 is an input/output control mechanism, 5 is a buffer, and 6 is a printer.

7 is a timer/calendar mechanism, 8 is a sense information path,
9 is a control signal path.

Here, 2 and 3 are also called peripheral devices.

When a failure check circuit (not shown) detects a failure in the input/output device f3 or the device 002, the input/output control mechanism 4 creates a sense gutter along with operating environment information, etc., and stores it in the buffer 5. Along with the timer/calendar mechanism, you can read the date and time at the time of failure from 0PUI! I
Do n. After that, the hexadecimal number (or decimal a) is sent to the printer 6.
), print out the date and time, the physical machine number of the failed device, and the sense gutter, and clear the contents of the buffer 5. If you require full compatibility with conventional methods,
When clearing vaginal buffer 5 after printing out, CP
The contents of the buffer may be held in a suspended state until a sense data retrieval request or reset instruction is received from U. Furthermore, if you use the sense data selection circuit, you can selectively print out only the necessary data. It is also possible to fully improve the performance of the printer or increase the processing capabilities of the microprogram in the machine 002 to analyze all of the sense information and display all of the information in literal format, such as the print pseudonym of the occurrence of the problem and information that will provide clues for repairing the problem.

(6) According to the present invention as described in detail, ■ 5EN at the time of failure
Since the SK information is output to the printer of the device each time it occurs, the 17j can reduce the amount of failure accumulation file money required. (ID 0PUK
Even when a failure occurs or the CPU is unavailable, the failure accumulation information is output to the printer of the IOC, making it possible to avoid a situation in which the failure accumulation file cannot be used. [
Stock] Accumulated failure information will not become unusable due to a failure occurring in the failure accumulation file. [stock] apt
In y, performance is improved because input/output operations for failure handling can be omitted and the load is reduced. ■ The work of the operator to periodically process the entire output of the failure accumulation file can be reduced, reducing the operator's effort. ■ It is possible to select and print out the necessary sense gutter, which has the effect of further reducing operator judgment.
