ABSTRACT:
When an I/O request block is received from a file system, a number-of-system's-failures setting section stores the present number of failures in the I/O request block, and hands over the I/O request block to a software driver after taking a checkpoint. When the I/O request block is received from the software driver, a number-of-failures determining section determines whether or not the number of failures stored in the I/O request block coincides with the present number of failures. If they do not coincide, an I/O request error return section will return the I/O request block to the software driver without handing over it to a device driver and causes an I/O request completion processing section to reissue the I/O request block again.
