<p>In a computer system, when a CPU (1a, 1b) performs state setting of an operation mode or the like to I/O devices (4a, 4b), the log data of the state setting is stored in a set log storage area. Upon occurrence of a fault in the computer system, the I/O devices are cleared, and state setting of the I/O devices is performed on the basis of the log data of the state setting stored in the set log storage area (34). Therefore, the states of the I/O devices can be recovered to a state at a checkpoint when the process is restarted. <IMAGE></p> |
