Abstract

PURPOSE:To quickly perform maintenance by analyzing error information by a service processor to estimate a trouble position at the time of recording error log information and recording information related to the trouble position also as error log information. CONSTITUTION:If some hardware error occurs in an operation processor 10, this occurrence is transmitted to a service processor 20 by a hardware error occurrence signal 101. At this time, the service processor 20 reads in error information 40 from the operation processor 10 through a data line 102 and starts an error log analyzing mechanism 210. The error analyzing mechanism 210 estimates a trouble card in accordance with error information 40 and a correspondence table 220. After estimating the trouble card, the service processor 20 writes trouble card estimating information from the error log analyzing mechanism 210 and error information 40 from the operation processor 10 in an error log area on a disk 30 through an interface 201.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an error logging system in which error information in an arithmetic processing unit is read by a service processing unit and recorded in an error log area.

[Conventional technology]

In the conventional error logging method, the service processing unit simply reads the error information in the arithmetic processing unit and writes it to the error log area on the disk without changing the information, and all tasks such as estimating the location of the failure require manual intervention. It was carried out by

In other words, during maintenance work, error log information recorded in the error log area on the disk is displayed as a hardware display screen on the service screen, and this display information and a previously created correspondence table of errors and failure locations are used to display the error log information recorded in the error log area on the disk. This involves manually estimating the location of the failure.

There has also been a method in which a microdiagnosis is executed on an arithmetic processing unit, and a failure location is manually estimated from the execution result and a correspondence table between error messages and failure locations created in advance.

[Problem that the invention seeks to solve]

In the conventional error logging method described above, which records only error information within the processing unit and analyzes the error information through manual intervention or estimates the failure location by utilizing microdiagnosis, , Since all analysis is done manually, it takes a lot of time to estimate the failure location, which increases maintenance time. It is easy for errors to occur during the analysis. It takes a lot of time to estimate the failure location. There were problems such as the knowledge and experience required.

This invention was made in order to solve the above-mentioned problems, and it records the estimated failure location along with error information as an error log, thereby eliminating the need for manual failure location estimation during maintenance work. The purpose is to provide a method.

[Means for solving problems]

In the error logging method according to the present invention, the service processing device is provided with a fault location estimating means for estimating the fault location by analyzing error information from the arithmetic processing device, and information regarding the estimated fault location is sent to the service processing device along with the above error information. It is designed to record in the log area.

[Effect]

According to this invention, when an error occurs in an arithmetic processing device, the service processing device automatically estimates the location of the failure based on the error information, and information regarding the failure location is stored in a predetermined error log together with the error information as error log information. recorded in the area.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a block configuration diagram showing an error logging method according to an embodiment. In the figure, 10 is an arithmetic processing unit, which is usually composed of a plurality of cards on which a CPU, memory elements, etc. are mounted, and here, #1 card 1) 0. It is assumed that the game consists of three cards: #2 card 120° and #3 car) '130. 20 is a service processing device, 3
0 is a disk connected to the service processing device 20 for recording error log information, and 40 is the arithmetic processing device 10.
error information read into the service processing device 20,
Reference numeral 210 denotes an error that analyzes the error content from this error information 40 to estimate the failure location, and the error log analysis mechanism 210 and the correspondence table 220 constitute the failure location estimation means 230 of the present application. Note that 101 is a hardware error occurrence signal of the arithmetic processing device 10, 102 is a data line for the service processing device 20 to read error information 40 from the arithmetic disconnection device 10, and 201 is a line between the service processing device 20 and the disk 30. It is an interface.

FIG. 2 is a specific example of the above-mentioned correspondence table 220, in which "x"
It is assumed that the card corresponding to the mark is malfunctioning.

FIG. 3 shows a specific example of the error information 40 mentioned above, 401.
402, 403, 404, and 405 correspond to error bits A, B, C, D, and H in FIG. 2, respectively.

Next, the operation will be explained.

If any hardware error occurs in the arithmetic processing device 10, it is transmitted to the service processing device 20 by a hardware error occurrence signal 101. At this point, the service processing device 20 transfers the error information 40 to the arithmetic processing device 10.
Then, the error log analysis mechanism 210 is started. The error log analysis mechanism 210 estimates the malfunctioning card from the error information 40 and the correspondence table 220.

For example, error bit A shown at 401 and 403 in FIG.
, C are set, the error log analysis mechanism 210 searches the correspondence table 220 as shown in FIG. It is estimated that the #3 card 130 is out of order, and since the error bit C is set, it is estimated that the #3 card 130 is out of order.

When the estimation of the faulty card is completed, the service processing device 20
writes the failed card estimation information obtained from the error log analysis mechanism 210 and the error information 40 from the arithmetic processing unit 10 together into the error log area of the disk 30 via the interface 201 .

As described above, along with the error information, information regarding the faulty card automatically estimated by the service processing device 20 is stored on the disk 3.
Since the error log information is written on the disk 30 during maintenance, a faulty card can be recognized immediately and without error by simply reading and displaying the error log information from the disk 30.

Note that in the above embodiment, the correspondence table 220 is configured using a ROM, but it may also be implemented using a RAM or an external storage device such as a disk device.

Furthermore, in the above embodiment, the fault location is pointed out on a card-by-card basis, but this may be done on an element-by-device basis or on a device-by-device basis.

〔Effect of the invention〕

As explained above, according to the present invention, when recording error log information, the service processing device analyzes the error information to estimate the failure location, and information regarding this failure location is also recorded as error log information. Therefore, during maintenance work, there is no need for manual intervention for estimating the location of failure, and maintenance work can therefore be performed quickly and without errors, regardless of the level of knowledge and experience of the maintenance worker.
