Abstract

PROBLEM TO BE SOLVED: To efficiently cope with a fault of the system by allowing a remote maintenance center to have a fault diagnosing function. SOLUTION: If a fault occurs to a computer main body 11 in the computer system 1, fault information is gathered and sent to a fault diagnostic device 12 in the computer system 1. The fault diagnostic device 12 does not analyzes the fault, but transfers fault information to the remote maintenance center 2 through a communication network. Relating to the fault diagnostic device 21, the transferred fault information confirms a replaced component name needed for replacement due to the fault and the place (location information) in the computer where the component is present by using a fault dictionary 22. The replaced component name and location information are sent back to the computer system 1 through the communication network and stored on a DISK drive 13 in the fault diagnostic device 12. The information can be referred to from the computer main body 11.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a computer system fault diagnosis system.

[0002]

2. Description of the Related Art Conventionally, a failure analysis of a computer system is performed by identifying a failure location of a computer when a failure has occurred, a name of a component that needs to be replaced in order to replace a failed component, and a location of the failed computer. (Location in the computer) is used to indicate to maintenance personnel.

In such a failure analysis, a failure dictionary is generally provided in a failure diagnosis device provided in the same system as a computer, and when a failure occurs, an analysis process using this failure dictionary is performed. Identify the part name, etc.

[0004]

However, according to the above-mentioned method, it is necessary to change or correct the name of the replacement part of the computer in the middle or to change or correct the failure dictionary in order to improve the failure analysis capability. When this occurs, it is necessary to replace the fault dictionary in the fault diagnosis device in the computer in order to replace the content by this change and correction, and the problem that the time and cost required to replace all the existing devices is too large. there were.

[0005] Further, since a failure analysis process is performed for each computer, a processing device which satisfies the processing load,
In other words, a high-speed arithmetic device is required, and a DISK device for storing a large-capacity fault dictionary needs to be secured.

The present invention has been made in view of such a background, and provides a failure diagnosis method for a computer system in which a remote maintenance center is provided with a failure diagnosis function so that a system failure can be efficiently dealt with. The purpose is to do.

[0007]

According to a first aspect of the present invention, a plurality of computer systems each including a first fault diagnosis device are connected to the plurality of computer systems via a communication network to perform fault analysis. A failure diagnosis method for a computer system comprising a remote maintenance center having a second failure diagnosis device having a failure dictionary is provided.

[0010] According to a second aspect of the present invention, the failure dictionary determines a replacement part name and location information of the part from failure information of a failure that has occurred in the computer system transmitted through the communication network. The computer system fault diagnosis system according to claim 1, wherein the system can be referred to from a computer main body in the computer system.

According to a third aspect of the present invention, there is provided the computer system fault diagnosis method according to the first or second aspect, wherein the communication network is a wired communication network.

According to a fourth aspect of the present invention, there is provided the fault diagnosis system for a computer system according to the first or second aspect, wherein the communication network is a wireless communication network.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a failure diagnosis system for a computer system according to an embodiment of the present invention. Referring to FIG. 1, a remote maintenance center 2 having a failure dictionary 22 and having a failure diagnosis device 21 for performing failure analysis of the system is connected to the computer system 1 via a communication network. Computer body 11 in computer system 1
Has a DISK device 13 and is connected to a failure diagnosis device 12 for providing a failure diagnosis service.

The remote maintenance center 2 is connected to the computer system 1 by a communication network, and fault information collected for a fault occurring in the computer system 1 is transmitted to the fault diagnosis device 21 in the remote maintenance center 2 via the communication network. To determine the replacement part name and the location (location information) in the computer system 1 where the part is located from the failure information by the connected failure dictionary 22. Then, the information is stored in the DISK device 13 in the computer system 1 via the communication network, and can be referred to from the computer main body 11.

Next, the operation of this embodiment will be described with reference to FIGS. First, computer system 1
When a failure occurs in the computer body 11 in the computer, failure information as failure information is collected in step S1 (hereinafter, S1) in FIG. 2 and sent to the failure diagnosis device 12 in the computer system 11. In the failure diagnosis device 12, failure information is transferred to the remote maintenance center 2 via the communication network without performing failure analysis (S2).

The transmitted fault information is used by the fault diagnosis device 21 to determine the name of a replacement part required for replacement due to the fault and the location (location information) in the computer system 1 where the part is located (S3). . And
The replacement part name and the location information are returned to the computer system 1 via the communication network (S4), and stored in the DISK device 13 in the failure diagnosis device 12 (S4).
5).

The operation of one embodiment of the present invention has been described in detail with reference to the drawings. However, the present invention is not limited to this embodiment, and a design change or the like may be made without departing from the gist of the present invention. The present invention is also included in the present invention.

[0016]

As described above, the first effect of the present invention is that a fault diagnosis apparatus having a fault dictionary is placed at a remote maintenance center, so that a fault dictionary associated with a change in the name of a computer component can be obtained. If the failure dictionary is modified due to a change in the failure analysis or the performance improvement of the failure analysis capability, the replacement of the failure dictionary needs to be performed for the remote maintenance center that is overwhelmingly smaller than the total number of computers. It is possible to do.

The second effect is that the processing used for the failure analysis is not performed by the failure diagnosis device in each computer system, so that the processing load on the failure diagnosis device can be reduced.
This does not require a device for securing a place (DISK device) for storing a fault dictionary in the device, so that a low-cost fault diagnosis method can be obtained.
