The present invention relates to a storage device which is defined by a logical volume, and makes it possible to perform processing, such as duplication of a logical volume, without using environmental construction and hardware resources of a host server side. The storage device has a storage part (a storage), which is constituted by a recordable storage medium and is defined by one or a plurality of logical volumes, and a storage control part (a storage server) which controls operation of the storage part. For control of the operation of the storage part defined by the logical volume, management information which is stored in a data base part (a data base) is referenced.
