Abstract:
1. A CPU suppression system comprising: a service processor; and an operational system that contains a CPU, the CPU executing a micro program for performing a diagnosis of a unit in the operational system including the CPU, wherein the service processor performs a CPU check of an operational system, gives CPU control to the micro program when the service processor determines that the CPU has a capability of performing basic operations using its own hardware resources using the CPU check, monitors error occurrences in the CPU of the operational system while the CPU executes the micro program, and corrects CPU-in-error information when any CPU error is detected, and the CPU executes the micro program when the CPU control is given from the service processor, obtains CPU-in-error information from the service processor immediately before completing the diagnosis by the micro program, and makes a request for suppression of a CPU showing signs of unstable operation to the service processor on the basis of the obtained CPU-in-error information.
