摘要： PROBLEM TO BE SOLVED: To provide a maintenance technique for a disk array device, enabling even a maintenance person having no technical knowledge to perform active maintenance of a plurality of parts mounted on the disk array device in a correct order even in for a multiple failure.
SOLUTION: When the maintenance person selects a multiple failure active maintenance on a maintenance operation menu (S40), a maintenance PC transmits a multiple failure active maintenance selection command to the disk array device (S41). In the disk array device, a CM activates a multiple failure active maintenance order determination program (S42). The multiple failure active maintenance order determination program creates a part maintenance order table in which parts to be maintained are arranged in the order of maintenance and replacement. The content of the formed part maintenance order table is transmitted to the maintenance PC (S43). The maintenance PC displays maintenance object parts in the order designated by the part maintenance order table on a multiple failure active maintenance menu screen.

摘要： PROBLEM TO BE SOLVED: To provide a technology for appropriately performing rebuilding when one of two storages (hot spares) allocated to the two failed storage for rebuilding fails while rebuilding.
SOLUTION: When a disk HS0 fails while rebuilding that uses two disks HS0 and HS1, a disk HS2 is allocated for rebuilding of the failed disk HS0 and the two disks are rebuilt. A method for rebuilding changes depending on whether or not areas rebuilt in a non-failed disk HS1 are continuous. When the areas are not continuous, rebuilding of the two disks are performed independently; when the areas are continuous, rebuilding of the two are performed in link.
