Abstract
An information processing system includes a plurality of storage devices, a plurality of data access devices, and a first processor. The first processor selects, when a first data access device permitted to access data in a first storage device fails, a second data access device other than the first data access device. The first data access device is included in the plurality of data access devices. The first storage device is included in the plurality of storage devices. The second data access device is included in the plurality of data access devices. The first processor permits the second data access device to access data in the first storage device. The first processor updates correspondence information, which indicates the first data access device as a transfer destination of a request to access first data in the first storage device, to indicate the second data access device as the transfer destination.
