Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure information collecting method for an information processing apparatus, and more particularly to an operating system (O).
A method of collecting fault information from a service processor (abbreviated as S) to a service processor (abbreviated as SVP).

[0002]

2. Description of the Related Art Conventionally, when an OS is down while an OS is running or an error occurs in a peripheral device, the OS detects the error and outputs it to the console of the OS.

[0003]

In the conventional fault information collecting method described above, since the OS down and the error of the peripheral device are displayed only on the console of the user, the maintenance person cannot recognize the fault. In addition, collection of fault information,
There is a problem that the treatment cannot be speeded up.

The present invention has been made in view of the above-mentioned problems, and makes it possible to collectively notify the SVP of failure information of an OS down while the OS is running and errors of peripheral devices to facilitate acquisition of the failure information. It is an object of the present invention to provide a failure information collection method for notifying a maintenance center to improve maintainability and speed up treatment for serious failures.

[0005]

According to the method of collecting fault information of the present invention, in an information processing apparatus having a service processor, the operating system has a system down detecting means and a peripheral device error information collecting means, and In the service processor communication area, the central processing unit comprises failure notification means for the service processor, and the operating system stores operating system down and peripheral device error information in the service processor communication area and reports to the service processor. The service processor reads the communication area and collects the information on a disk. Further, the service processor has a line control means and an automatic dial means, and automatically notifies the maintenance center of the information notified from the operating system.

[0006]

According to the above construction, the operating system stores the failure information detected and collected by the system down detecting means and the peripheral device error information collecting means in the service processor communication area of the main storage device, and the failure of the central processing unit. When a failure is reported from the notification means to the service processor, the service processor receives the notification and reads the failure information stored in the communication area into the disk, so failure information of system down and peripheral device error is sent to the service processor. It can be collected collectively.

Alternatively, the fault information collected in the disk by the service processor is automatically notified by connecting the line from the automatic dialing means to the maintenance center by means of the line control means. Post-treatment can be performed.

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a system schematic diagram of a fault information collecting method according to an embodiment of the present invention. In FIG. 1, a main memory unit (abbreviated as MMU) 2, an input / output device (abbreviated as IOP) 3, and a service processor (SVP) 4 are connected to a central processing unit (CPU) 1. Communication area 21 is MMU2
The communication area used for communication between the OS and the SVP 4 is shown. The SVP 4 has a console (CRT, keyboard, etc.) 5 for conversation with an operator and a disk 6 for storing failure information, and is connected to the maintenance center 7 via a communication line. The OS on the CPU 1 collects failure information and reports it to the SVP 4. C on the MMU2
The communication area 21 for the error log (OS down, fault information of peripheral device error) from the PU 1 is secured. SVP4 is C
When receiving a failure report from the PU 1, the error log is read from the communication area 21, the failure information is obtained, and the maintenance center 7 is notified.

FIG. 2 is a detailed system diagram of a fault information collecting method according to an embodiment of the present invention. In FIG. 2, the system stores in the communication area 21 of the MMU 2 the information collection means 11 such as an OS down, a damper for collecting fault information of peripheral device errors, an I / O processing routine, etc. in the CPU 1. Error log storage means 12, CPU
Fault communication means 1 for reporting the occurrence of fault from SVP4 to SVP1
3 and the error log from the communication area 21, read the disk 6
Error logging means 41 in the SVP4 for logging into the.

FIG. 3 is a flow of a fault information communication method when a fault occurs in the system.

Next, the operation will be described with reference to the flow of FIG.

When the OS is down, the damper in the OS which is the information collecting means 11 collects the information (process 81), and the peripheral device error when the I / O command is abnormal is the I / O in the OS.
The O process routine collects the information (process 82). O
The S stores the collected error log in the communication area 21 of the MMU 2 by the error log storage means (process 83). Next, the OS instructs the CPU 1 to SVP4 by the instruction of the CPU 1.
The failure communication means notifies the failure occurrence (Process 8).
4). The SVP 4 that received the notification is the error logging means 41.
Reads the error log from the communication area 21 (process 8
5), logging to the disk 6 (process 86).

The second embodiment of the present invention will be described below.

FIG. 4 is a block diagram of a service processor according to a second embodiment of the present invention.

In FIG. 4, SV in the case of the second embodiment
P4 reads the error log logged by the automatic dialing means 42, the line control means 43 for making a line connection with the report destination (maintenance center 7), and the error logging means 41 from the disk, and reports the contents to the connection destination. The communication means 44 is provided.

FIG. 5 is a flow chart of a fault information reporting method when a fault occurs in the system according to the second embodiment.

Next, the operation will be described with reference to the flow of FIG. When the OS notifies the SVP4 that a failure has occurred, the SV
P4 calls the automatic dial means 42 (process 91), and the line control means 43 establishes a line connection with a preregistered (in this case, the maintenance center 7) report destination (process 92).
When the line is connected, the communication means 44 of the SVP 4 reads the error log from the disk 6 (process 93) and reports the contents to the maintenance center 7 (process 94).

[0019]

As described above, according to the present invention, O
Fault information of OS down during execution, peripheral device error is S
Since the information is collectively collected in the VP, the maintainer does not overlook the failure information and can easily obtain the failure information, which has the effect of improving the maintainability.

Further, by reporting the failure information notified from the OS to the SVP to the maintenance center, it is possible to promptly deal with a serious failure such as an OS down or a peripheral device failure, and the peripheral device is relieved by the retry of the OS. There is also an effect that predictive maintenance can be performed from the intermittent failure information.
