| Zusammenfassung: | A host computer is connected to logical disks via controllers, and accesses the logical disks. When maintenance work is performed on a first controller, information indicating that the first controller is undergoing maintenance work is stored in the other controllers. When an access is made to a logical disk designating a path including the first controller, a redundancy driver of the host computer can discriminate the cause for an access failure based on the information stored in the other controllers even if the access fails. |
