<p><P>PROBLEM TO BE SOLVED: To provide a fault recovery method that can shorten the time required to initialize expansion devices before starting an OS. <P>SOLUTION: A computer system includes a main apparatus, a plurality of expansion devices, and a service processor for controlling the operation of the main apparatus. When power is restored to the main apparatus after a fault, the service processor initializes only a first device group of devices out of the plurality of expansion devices which is necessary to boot an operating system, and after initializing the first device group, starts the operating system. After the operating system is started, a CPU executes fault handling on the operating system. After the fault handling is started by the CPU, the service processor initializes a second device group of devices out of the plurality of expansion devices, which is other than the first device group. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
