DESCRIPTION OF THE PREFERRED EMBODIMENTS The IPL management method and apparatus for a computer system according to the present invention will be explained in detail below. The computer system of the present invention is designed to enable IPL processing to be recovered by retrying the process. First, an IPL management method in the computer system will be briefly described.

[0010] IP in such a computer system
The L management method includes a power-on start stage for supplying power supply voltage to perform IPL processing by outputting a elapsed signal when a predetermined time interval elapses, and a power-on start stage after this power-on start stage. a power-on interruption stage of outputting a first excess signal to cut off the supply of power supply voltage and interrupting the IPL process when count information obtained by counting the passage of time exceeds a predetermined first tolerance range; It takes.

[0011] Then, when the count information obtained by counting the passage of time after the power-on interruption stage exceeds a predetermined second tolerance range, a second excess signal is output, and the power supply voltage is stopped. There is a need to provide a power-on restart phase to restart and restart the IPL process.

Specifically, an IPL management device in a computer system may be configured as shown in one embodiment in FIG. Here, in addition to a file management section 1 that stores processing information such as the loader, IPL, and OS, and a timer section 4 that outputs a elapsed signal when a predetermined time interval elapses, this elapsed signal is inputted. A power supply control section 3 is provided that outputs a power-on start signal for occasionally supplying power supply voltage. Moreover, this power supply control section 3
is the power supply voltage when inputting the first excess signal that is output when the count information obtained by counting the elapsed time after the power-on start signal is output exceeds a predetermined first tolerance range. outputs a power-on interrupt signal to cut off the supply of When the second excess signal is inputted, a power-on restart signal for restarting the supply of power supply voltage is output.

For this reason, the IPL management device further outputs first and second excess signals to the power supply control unit 3, and also detects the elapsed time after the power-on start signal or the power-on interruption signal is output. The system includes a processing time monitoring section 5 that counts processing time, and a system main body 2 connected to a file management section 1 and a power supply control section 3. The system main body 2 is driven when a power-on start signal or a power-on restart signal is input from the power control section 3, reads loader and IPL processing information from the file management section 1, and performs IPL processing, while the power control section When a power-on interruption signal is input from step 3, the IPL processing is stopped and the IPL processing is interrupted.

Among these, the power supply control section 3 is connected to the system main body 2, a timer section 4, and a processing time monitoring section 5 so that signals can be exchanged with each section. Further, the file management section 1 and the system main body 2 are also connected so that signals can be exchanged between them. Furthermore,
The system main body 2 has an IPL connection between it and the file management section 1.
A CPU and memory (not shown) are provided for processing. The second tolerance range based on each count information has a longer count than the first tolerance range.

[0015] In the IPL management device in the computer system having such a configuration, the power supply control unit 3 inputs the elapsed signal outputted from the timer unit 4 when a predetermined time interval has elapsed, and the power supply control unit 3 turns on the power to the system main body 2. Since the start signal is output, power supply voltage is supplied to the system main body 2, and a power-on start stage for performing IPL processing is obtained. That is, the system body 2 to which the power supply voltage is supplied performs the IPL process by reading processing information such as the loader and IPL from the file management unit 1.

At this time, the processing time monitoring unit 5 counts the elapsed time after the power-on start signal is output, so when the count information exceeds a predetermined first tolerance range, the processing time monitoring unit 5 An excess signal is output to the power supply control section 3. Then, the power supply control unit 3 that has received the first excess signal outputs a power-on interruption signal to the system main body 2. As a result, a power-on interruption stage for interrupting the IPL processing by the system body 2 is obtained.

Furthermore, since the processing time monitoring section 5 counts the elapsed time after the power-on interruption signal is output, when the count information exceeds a predetermined second tolerance range, a second excess signal is generated. is output to the power supply control section 3. Then, the power supply control unit 3 inputting the second excess signal,
A power-on restart signal is output to the system main body 2. As a result, a power-on restart stage for restarting the IPL processing by the system body 2 is obtained.

Therefore, in the IPL management method and apparatus for a computer system of the present invention, when IPL processing is performed after the power-on start stage, a power-on start signal is output regardless of whether or not a failure occurs during the IPL process. The system counts the time elapsed after the IPL is started, and when the count information exceeds a predetermined first tolerance range, a power-on interruption signal is output.
Processing is interrupted. This first tolerance range is normal IPL
It is set to have count information that is longer than the processing completion time. That is, if a failure occurs during the IPL process, the IPL process will be interrupted, and if no failure occurs, the IPL process will be completed.

Then, the time elapsed after the power-on interruption signal was output is counted, and when the count information exceeds a predetermined second tolerance range, the power-on restart signal is output, so that the IPL processing is performed. Even if the IPL is interrupted due to a failure in the middle, the IPL by the system main unit 2
By restarting the process and retrying, it is possible to avoid system start-up and halt due to recoverable intermittent failures.

[0020]

As described above, according to the present invention, even if IPL processing is interrupted midway, it is possible to automatically retry the IPL processing in a computer system to avoid system start-up and stoppage due to IPL processing failure. A management method and apparatus are provided. As a result, unnecessary operation stoppages in system operation are reduced, and the probability that system operation continues normally can be improved.
