Abstract
A method and appartus maintain a disk drive system in a more reliable and simplified manner. Maintenance commands directed to logical volumes of the physical disk drive units are configured to apply to the entire physical disk drive unit so that a maintenance command need not be repeated for each logical volume to be affected. Should a failure be received with regard to any one or more logical volumes, the apparatus and method repeat the maintenance command, but only for those failed logical volumes. The maintenance command can also be applied to a group of physical devices using this procedure.
