Abstract
A storage system and storage control method are provided in which a plurality of volumes to be processed by a storage control unit are distributed and evacuated in a normal storage control unit without recovering redundancy of the storage control unit having decreased redundancy, and the storage control unit itself having the decreased redundancy is deleted after the evacuating is completed, and thus reservation information processing resources for guaranteeing recoverability of the redundancy become unnecessary.
