Abstract

PURPOSE:To contrive the improvement of the maintenance property by diagnosing a device in accordance with a result of analysis of a state of the device in which a fault is generated, and also, diagnosing again the device in response to an external signal which is inputted after a maintenance work corresponding to a result of diagnosis of the device is executed. CONSTITUTION:When an error is generated due to a fault of a circuit, etc. in the course of operation of each device such as an operation processor, an input/output processor or a storage device, etc. in a central processor 1, a state signal for showing an operating state is sent out to an error processing part 2. The error processing part 2 sends out a device state to a diagnostic control part 4, and when the diagnosis can be executed, the diagnostic control part 4 outputs a diagnostic execution request of the device in which an error is generated to a diagnostic execution part 3. In such a way, the diagnosis is executed by the diagnostic execution part 3, a maintenance work corresponding to a result of its diagnosis is executed by a maintenance person and an operator, and thereafter, in response to a diagnostic request inputted by an operation of a diagnostic operation part 5, the device is diagnosed by the diagnostic execution part 3. In such a way, the diagnosis at the time when a fault is generated is executed automatically, and the maintenance property is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION 1. Upright 1 The present invention relates to an information processing device, and more particularly to a diagnostic processing device having a function for performing diagnosis on each device within the information processing device.

Conventionally, in this type of diagnostic processing equipment, diagnostic operations for each device in the central processing unit were performed only by instructions from a diagnostic operation section that was directly operated by maintenance personnel, operators, etc. Decisions about program execution were also made by maintenance personnel, operators, and others.

In such conventional diagnostic processing devices, diagnostic operations for each device are directly instructed by maintenance personnel or operators from the diagnostic operation unit (console, etc.), and diagnostic programs are executed in response to these instructions. In the event of a failure, maintenance personnel, operators, etc. must identify the location of the failure, which has the drawback of requiring a large amount of time to analyze and restore the failure.

The present invention has been made to eliminate the drawbacks of the conventional devices as described above, and provides an information processing device that can analyze and restore failures in a short time and improve maintainability. The purpose is to provide.

1. An information processing device according to the present invention includes: an analysis means for analyzing the state of a device in which a failure has occurred; a diagnosis means for diagnosing the device; diagnostic control means for issuing a diagnostic execution command to the diagnostic means, and for issuing the diagnostic execution command to the diagnostic means in response to an external signal input after maintenance work is performed according to the diagnosis result of the diagnostic means; It is characterized by having.

1. Next, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In FIG. Status signals indicating the operating state of the device, such as error signals, stop signals, or phase signals sent from the device, are processed.

The diagnosis execution unit 3 executes a diagnostic program for diagnosing the circuits of each device in the central processing unit 1.

When the diagnosis control unit 4 determines that diagnosis can be executed based on the status signal of each device from the error processing unit 2, it instructs the diagnosis execution unit 3 to diagnose the device, holds the diagnosis result, or When a diagnosis request is input from the diagnosis operation unit (operation console, etc.) 5, it instructs the diagnosis execution unit 3 to diagnose the device and holds the diagnosis results.

Next, the operation of one embodiment of the present invention will be explained using FIG.

If an error occurs due to a circuit failure during the operation of each device such as the arithmetic processing unit, input/output processing unit, or storage device in the central processing unit 1, and a retry is not possible or a retry fails, an error has occurred. Processing is interrupted in a device, for example, an arithmetic processing unit, and a status signal indicating an operating state such as error details, processing being stopped, or operation phase is sent to the error processing unit 2.

The error processing unit 2 analyzes the status signal from the central processing unit 1 and sends the device status to the diagnostic control unit 4.
determines whether diagnosis can be executed based on the status of the device in which the error has occurred and other devices in operation, and if it is possible to execute the diagnosis, requests the diagnosis execution unit 3 to execute the diagnosis of the device in which the error has occurred. Output.

Further, the diagnostic control section 4 identifies the circuit that has caused the failure based on the device status sent from the error processing section 2.

On the other hand, when the diagnosis execution unit 3 receives a diagnosis execution request from the diagnosis control unit 4, it starts a diagnosis program and executes diagnosis of the device in which the error has occurred.

At this time, diagnosis is performed only on devices whose processing has stopped due to an error, while normal operations continue on devices that are normal.

When the diagnostic program ends, the diagnostic execution unit 3 reports the diagnostic results to the diagnostic control unit 4.The diagnostic control unit 4 analyzes the diagnostic results to identify the circuit that has caused the failure.
The results are held and the device status is checked by the diagnostic operation unit 5.
Report to.

The diagnostic operation section 5 displays the operating status of each device within the central processing unit 1. The maintenance person or operator looks at the operating status of each device displayed on the diagnostic operation section 5, and if there is a device whose processing operation has stopped, causes the diagnostic operation section 5 to display the diagnosis result of the diagnosis execution section 3, Refer to the diagnosis results and take necessary measures such as repairing the circuit.

In addition, maintenance personnel and operators output a diagnostic request from the diagnostic operation unit 5 to the diagnostic control unit 4 in order to check whether the circuit that has undergone necessary measures such as repair has become normal. A device including the circuit is diagnosed to check the validity of the device.

In this way, the diagnosis execution unit 3 diagnoses the device that has stopped processing due to a failure, and after maintenance work is performed by the maintenance staff or operator according to the diagnosis results, the maintenance staff or operator performs the diagnosis. By diagnosing the device by the diagnosis execution section 3 in response to a diagnosis request inputted by operating the operation section 5, it is possible to automatically diagnose when a failure occurs.

Therefore, failure analysis and recovery can be performed in a short time.
Maintainability of the central processing unit 1 can be improved.

As explained above, according to the present invention, a device in which a failure has occurred is diagnosed in accordance with the analysis result of the state of the device, and maintenance work is performed in accordance with the diagnosis result of the device. By diagnosing the device in response to an external signal that is input after the device has been used, failure analysis and recovery can be performed in a short time, and maintainability can be improved.
