摘要：
One or more master CHN 21AM and one or more back-up CHN 21AC are provided. In each of the one or more back-up CHNs 21AC, the I/O processor 504 is in a power on state, and the NAS processor is in a power off state. The I/O processor 504 accesses a shared memory 25 periodically, and if the fact that a problem has occurred in any master CHN 21AM has been written to the shared memory 25, then the power supply of the NAS processor 506 is turned on, and processing is carried out for switching the back-up CHN 21AC in which the I/O processor 504 is installed, to a master CHN 21 AM.
