JPH041827A - Fault restoration system for computer - Google Patents

Abstract

PURPOSE:To automatically, quickly and accurately restore a hardware fault by combining the output of a diagnostic program with an unmanned robot which switches a fault suspected package to a stand-by package. CONSTITUTION:A fully automatic fault restoring robot 3 starts a manual diagnostic program of a computer system 1 via an interface device 2 for robot 3. The computer system 1 transmits the running result of the manual diagnostic program to the robot 3 via the device 2. Thus the robot 3 stops its operation when deciding that the fault of the system 1 is restored. If the robot 3 decides that the fault of the system 1 is not restored yet, the robot 3 takes successively the stand-by packages out of a stand-by package store shelf 4 in response to other fault suspected packages and repeats the same operations. As a result, a hardware fault is automatically, quickly and accurately restored.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a computer failure recovery system, and in particular, when a computer system hardware failure occurs, the failure package is replaced according to suspect package information pointed out by an automatic diagnostic program, and the failure recovery system is performed. Concerning a computer disaster recovery system for recovering.

[Conventional technology]

Conventionally, in this type of failure recovery system, computer system maintenance personnel index and refer to diagnostic dictionaries and package implementation diagrams in accordance with suspected failure information pointed out by an automatic diagnostic program when a computer system hardware failure occurs. The system uses this method to learn the package name and its implementation location, and then replace the faulty package to recover from the fault.

[Problem to be solved by the invention]

As mentioned above, in conventional fault recovery systems, maintenance personnel replace the suspected faulty package pointed out by an automatic diagnostic program to recover from the fault.
If maintenance personnel are inexperienced, this may lead to work errors, and in order to recover from failures, maintenance personnel must be dispatched to the computer system installation site to replace the package. When performing remote maintenance, there is a problem that failure recovery takes time.

An object of the present invention is to provide a computer failure recovery system that can automatically perform failure recovery of computer system hardware in a short time and accurately.

[Means to solve the problem]

The computer failure recovery system of the present invention replaces a suspected failure package based on the suspected failure package information pointed out by an automatic diagnostic program when a hardware failure occurs, and recovers from the failure. and a computer system that outputs: mounting position information of all packages mounted in the computer system, position information of all spare packages stored in storage shelves on the storage shelves, and movement for package replacement. .

It has means for performing ejecting and inserting operations and information for the operations, and receives information on suspected defective packages output from the computer system, moves to the storage shelf, takes out and holds the corresponding spare package, and An unmanned robot that moves to a mounting position of a suspect package, replaces the suspect package with the corresponding spare package, then starts a manual diagnosis program of the computer and confirms failure recovery.

The present invention is configured to include an interface device for transmitting information between the computer system and the unmanned robot; and a rail for the unmanned robot to move between the computer system and the storage shelf.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.6 FIG. 1 is a diagram for explaining an embodiment of the present invention.

The computer failure recovery system includes a computer system 1 and a failure recovery robot/interface unit W2.
, an unmanned fully automatic failure recovery robot 3, a spare package storage 14, and a moving rail 5. The computer system 1 has a function of automatically diagnosing a hardware fault when it occurs and outputting information regarding a suspected faulty package to a fully automatic fault recovery robot 3 via a fault recovery robot interface device 2 . The fully automatic failure recovery robot 3 provides mounting position information of packages installed in the computer system 1.

A function for moving on the moving rail 5 to all the spare package mounting position information in the spare package storage shelf 4, the suspected failure package mounting position in the computer system 1, and the spare package mounting position in the spare package storage shelf 4. , an arm for removing and inserting a package, information for its operation, and a function for starting a manual diagnosis program of the computer system 1 and confirming failure recovery. The spare package storage shelf 4 stores spares of all the packages installed in the computer system 1, and when a spare package is used for failure recovery of the computer system 1, a maintenance person replenishes the corresponding package. It is assumed that a certain number of spares of all the packages installed in the computer system 1 are always stored.

The operation will be explained below. When a hardware failure occurs in the computer system 1, the computer system 1 starts an automatic diagnosis program and outputs the suspected failure package information obtained thereby to the fully automatic failure recovery robot 3 via the failure recovery robot interface M2. do. The fully automatic failure recovery robot 3 moves on the moving rail 5 to the location of the spare package storage shelf 4, and uses its arm to take out and hold the spare package of the suspected failure package based on the suspected failure package information. Next, the fully automatic fault recovery robot 3 moves on the moving rail 5 to the position of the suspected faulty package in the computer system 1 based on the suspected faulty package information, takes out the suspected faulty package with its own arm, and holds it. Then, the fully automatic failure recovery robot 3 starts the manual diagnosis program of the computer system 1 via the failure recovery robot interface device 2, and then inserts the spare package into the corresponding position with its own arm. transmits the running results of the manual diagnosis program to the fully automatic fault recovery robot 3 via the fault recovery robot interface device 2. As a result, if the fully automatic failure recovery robot 3 determines that the failure of the computer system 1 has been recovered,
If it is determined that the operation has stopped or has not recovered, take out the spare packages stored in the spare package storage shelf 4 in response to other suspected failure packages and carry out the same procedure as described above. Repeat the action.

〔Effect of the invention〕

As explained above, when a hardware failure occurs in a computer system, the present invention combines the output of a diagnostic program that points out a suspected faulty package in the computer system and an unmanned robot that replaces the suspected faulty package with a spare package. By configuring the system to recover from hardware failures, it is possible to automatically recover from computer system hardware failures in a short time and accurately.
