Abstract

PURPOSE:To reduce influence due to a change in device status information sampled at the time of generating a fault by executing the fault processing of a fault generator based upon the device status information stored in an external storage device and sampled information. CONSTITUTION:When a fault is generated in a device and informed to a diagnostic control device 2, a fault processing control part 21 is started and log-out data are sampled from the fault generator 1. After sampling the data, the control part 21 generates a log-out data receiving request to a service processor 3, which reads out log-out data for the generator 1 stored in a local memory 22 and stores the read data in a processor disk 31. Simultaneously, the log-out data corresponding to the generator 1 are read out from the memory 22 to the disk 31. The processor 3 executes the edition of the log-out data or the index of a fault position based upon the log-out data and log-out list of the generator 1 stored in the disk 31. Thereby, it is unnecessary to store the log-out list in both the processor 3 and the device 2.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a fault handling method, and in particular to information processing that reads out the device status of a faulty device when a fault occurs, and outputs it to an external storage device to perform fault processing. Related to equipment failure handling methods.

[Conventional technology]

Conventionally, this type of failure handling method reads the device status from the failed device when a failure occurs, outputs it to the external storage device, and then detects the failure according to the collected device status information held by the control device that controls the external storage device. Edited the index and device status at the time of failure.

[Problem to be solved by the invention]

The conventional fault handling method described above includes a control device that collects the device state information of the faulty device, and a control device that edits the fault index and device state information at the time of the fault from the device state information exported to the external storage device. Since the device status collection information is stored separately in both controllers, if the data type, data length, etc. of the device status information collected at the time of a failure changes, the collection information of the failed device status held in both control units will be changed. The drawback is that you have to do it.

[Means to solve the problem]

The failure handling method of the present invention includes means for storing collected information regarding the device status of a target device in advance, and means for reading device status information from the failed device according to the collected information stored in the storage means when a failure occurs. sending means for sending the device status information and the collection information sent from the reading device to an external storage device; the device status information and the collection information stored in the external storage device; The present invention is characterized in that failure processing for the failure generating device is performed based on the following.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. Referring to FIG. 1, the fault handling method of the present invention includes a diagnostic control device 2. As shown in FIG. This diagnostic control device 2 is equipped with a fault processing control section 21 and a local memory 22, and when a fault occurs, it reads device status information (hereinafter referred to as logout data) 11 to 1n from the faulty device 1 and stores it in the local memory 22. Store. Also, service brosé sosa 3
is equipped with a service processor disk 31 and a service processor software control section 32, and reads logout data into the service processor disk 31 in response to a request from the diagnostic control device 2, and performs data editing and fault indexing.

FIG. 2 is a diagram showing an example of a collection information list, which is referred to by the diagnostic control device 2 when collecting logout data from a failed device.

This list is created and resides in the local memory 22 when the diagnostic control device 2 is started up, and is a list of status information to be read from the failure device (hereinafter referred to as the logout list).
The data type, data amount, and offset address from the beginning of the area for storing logout data for each device are stored.

Next, the operation of each part according to the failure handling method of the present invention will be explained. The diagnostic control device 2 has predetermined diagnostic control software. When a failure occurs in the device and the diagnostic control device 2 is notified, the failure processing control unit 21 is activated and collects logout data from the failure device 1. At this time, the logout list of the corresponding device is read from the local memory 22 and stored from the beginning of the logout data storage area (hereinafter referred to as log area) of the corresponding failed device in the local memory 22 according to the address of the logout list. When all the logout data shown in the logout list of the failed device has been collected, the failure processing control unit 21 of the diagnostic control device 2 issues a logout data collection request to the service processor 3.

The service processor 3 that received the logout data collection request executes the service processor software control unit 32.
reads the logout data of the failed device 1 stored in the local memory 22 of the diagnostic control device 2, and
The information is stored in the service processor disk 31. At the same time, the logout list corresponding to the failed device is also read from the local memory 22 to the service processor disk 31. Then, the service processor 3 edits the logout data and locates the failure location based on the logout data and logout list of the failed device 1 stored in the service processor disk 31.

In this way, the service processor 3 receives the logout list used when the diagnostic control device 2 collects the logout data of the failed device 1 at the same time as the logout data, so that both the service processor 3 and the diagnostic control device 2 Since there is no need to maintain a similar logout list, the impact of changes to collected data can be reduced.

〔Effect of the invention〕

As explained above, when the diagnostic control device outputs the status information of the failed device to the external storage device, it also outputs the collected information on the status of the failed device at the same time, and provides services based on the status of the failed device stored in the external storage device. When the processor edits the fault index and faulty device state information, it does so based on the collected information that has been written out as the faulty device state information in the external storage device, and the diagnostic control device and service processor edit the collected information of the same faulty device state. By using this, it is possible to reduce the influence of changes in device status information collected when a failure occurs.
