In response to the detection of a system down, a preserve processing section first inhibits the switching of a standby main memory into a system. At this time, if the standby main memory is in an operating condition, the contents of the standby main memory are the same as the contents held in a working main memory. If the standby main memory is in a non-operating condition, the contents of the working main memory are copied to the standby main memory before inhibiting the switching of the standby main memory. Thereafter, the working main memory is initialized, and system operation is restarted. Next, after completing a freeze dump from the standby main memory to an external storage device, the standby main memory is released from the switching inhibited state.
