Abstract

PURPOSE:To facilitate subsequent error analysis by erecting representative EIF of its own system and erecting EIF of the data processor of the other system when an error occurs owing to the other data processor. CONSTITUTION:When the error occurs in the middle of an operation owing to the data processor 2, the representative error indicator flag(EIF) is erected on the representative flip flop (F/F) 11 of its own system in an error detection part 1-1, and other system EIF is erected on representative F/F 21 in the other data processor through an inter-device interface 100. The error is reported to a diagnosis device 3 through an inter-diagnosis device interface 200. When the diagnosis device 3 receives the report of the error, a log collection part 3-1 judges a device where EIF is erected by a device identification number and starts a log collection operation.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION The present invention is used for logging errors in information processing. The present invention relates to an information processing device that can collect not only logs of its own devices but also logs of suspicious devices.

0002

[Prior Art] Conventionally, in an error logging system for this type of information processing, if the cause of a failure is in another device and for some reason the error indicator flag (hereinafter referred to as EIF) of the device in which the failure occurred did not go up, There were cases where device logs were not taken.

0003

[Problem to be Solved by the Invention] As mentioned above, in the conventional error logging method, if the cause of a failure is in another device, the failure may not be detected and the log for that device may not be taken. This has the drawback that failure analysis becomes difficult and the true cause cannot be determined.

[0004] The present invention solves this problem, and even if the cause of the error is in another device and there is no EIF of the device that caused the error, it is possible to log the error.
It is an object of the present invention to provide a device that can easily perform subsequent error analysis.

[0005]

Means for Solving the Problems The present invention provides an information processing apparatus in which a plurality of data processing apparatuses are connected to each other via an inter-apparatus interface, and a diagnostic apparatus is connected to each other via an inter-diagnostic apparatus interface. Error detection in which the data processing device has a representative flip-flop that sets up a representative EIF when it detects a fault in its own system, and an other-system failure flip-flop that sets up an EIF in another system when it detects a fault in another data processing device. The diagnostic apparatus is characterized in that the diagnostic apparatus includes a log collection unit that collects log information from the data processing apparatus based on the apparatus identification number when the EIF of the data processing apparatus is raised.

[0006]

[Operation] When an error occurs due to another data processing device, the representative EIF of the own system is set up, and the data of the other system is processed assuming that the representative EIF of the own system was attached due to the other data processing device. Sets the device's EIF and reports errors to diagnostic equipment. Diagnostic equipment is EIF by equipment identification number.
Collect logs by determining which device is running.

[0007] Thereby, even if the cause of the error is in another device, failure logs can be collected, and subsequent error analysis can be easily performed.

Embodiments Next, embodiments of the present invention will be explained based on the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

In the embodiment of the present invention, the device interface 1
The data processing devices 1 and 2 connected to each other via the diagnostic device 3 and the diagnostic device interface 200
and 201, and each data processing device 1 and 2 has a representative flip-flop (hereinafter referred to as F/F/
An error detection unit 1- has an error detecting unit 11 and 21 (referred to as "F") and other system fault F/Fs 12 and 22 which set up another system EIF when a fault in another data processing device 2 or 1 is detected.
1 and 2-1, the diagnostic device 3 includes a log collection unit 3-1 that collects log information from the data processing device 1 or 2 based on the device identification number when the EIF of the data processing device 1 or 2 is set, and the representative F/F 11 and 21 include own system device identification numbers F/Fs 13 and 23 that hold the device identification numbers of own system data processing devices, and other system failure F/Fs 12 and 22 hold device identification numbers of other system data processing devices. The other system device identification numbers F/F 14 and 24 are included.

Next, the operation of the embodiment of the present invention constructed as described above will be explained.

When an error occurs during operation due to the data processing device 2, the error detection unit 1-1 sets a representative EIF in the representative F/F 11 of its own system, and
Through the inter-device interface 100, it is determined that the representative EIF of the own system has been set up due to the cause of another data processing device 2, and the other system E is sent to the representative F/F 21 of the data processing device 2 of the other system.
IF is set and the error is reported to the diagnostic device 3 via the diagnostic device interface 200. When the diagnostic device 3 receives the error report, the log collection unit 3-1 determines the device registered in the EIF based on the device identification number and starts a log collection operation.

For some reason, the representative F/F 21 of the data processing device 2, which is considered to be the cause of the error, has lost its representative EI.
If F is not set, the log collection unit 3 of the diagnostic device 3
-1 is the representative EI of the representative F/F 11 of the data processing device 1
Log collection is performed for data processing device 1 based on the contents of F and its own system device identification number F/F13 that has the device identification number of its EIF, but data processing device 2 that is considered to be the cause of the error Because the representative EIF is not set up in the representative F/F 21, the log collection unit 3- of the diagnostic device 3
1 does not collect logs because the data processing device 2 is not the cause of the error, but there is a failure F in another system of the data processing device 1.
Since the other system EIF is set at /F12, the log of the data processing device 2 is collected using the other system device identification number F/F14.

In this embodiment, an example is given in which there are two data processing apparatuses, but even for two or more data processing apparatuses, the error detection section can be provided with EIFs of as many different systems as there are data processing apparatuses. This can be achieved by having.

[0014]

As explained above, according to the present invention, even if the cause of the error is in another device and the EIF of the device that caused the error is not set, it is possible to log it as a suspect device. This has the effect of facilitating subsequent error analysis.
