Provided is a storage system capable of starting/stopping a disk drive. At the time of allocating a logical device, it is judged, based on attributes including a purpose of the logical device, whether or not control can be performed in terms of start/stop of an allocation target disk drive to determine an allocation destination disk drive. Further, in the case where access to a specific logical device is stopped due to release of a path definition or other such cause, it is judged whether or not a disk drive corresponding to the logical device can be stopped. When it is judged that the disk drive can be stopped, the disk drive is stopped. When it is judged that the disk drive cannot be stopped, the logical device is migrated to another disk drive that can be stopped, a migration destination disk drive is stopped.
