In a computer system to which a plurality of I/O devices are connected and a pool I/O device is included therein, a periodical operation confirmation is performed on a pool I/O device to be used when a fault occurs. A pool I/O device operation confirmation section obtains pool I/O device status information from a pool I/O device status information storage section (provided inside or outside the computer system). The status information includes a pool I/O device ID for identifying the pool I/O device, a type of the pool I/O device, a status value indicating an operation confirmation result, and an update time indicating the most recent operation confirmation time. Then, the pool I/O device operation confirmation section activates the pool I/O device and performs an operation confirmation thereon; terminates the operation of the pool I/O device after the operation confirmation; and updates the pool I/O device status information using the operation confirmation result obtained by the operation confirmation. |
