Abstract
In a computer system, when a CPU performs a state setting operation, such as setting an appropriate operation mode for I/O devices, the log data of the state setting operation is stored in a log storage area. Upon occurrence of a fault in the computer system, the I/O devices are cleared, and the state setting operation of the I/O devices is performed on the basis of the log data of the prior state setting operation stored in the log storage area. Therefore, the states of the I/O devices can be recovered to a state at a checkpoint when the process is restarted.
