Abstract

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.

Description

technical field [0001] The present invention relates to data storage and processing thereof using recordable storage media such as magnetic tape. Specifically, the present invention relates to a storage device in which a logical volume is defined, a data processing method thereof, a data processing program thereof, and a data processing system. Background technique [0002] A logical volume is defined in a storage device for storing various data, and processing such as replication and data copying is performed on the logical volume by a request from a host server. A recordable storage medium such as a magnetic tape is used for the storage device. In this recordable storage medium, positions are changed from old data to newest data to be added sequentially, and data is stored. Data of the storage device is managed by a host server as an external device. [0003] In addition, as related technologies related to such storage devices, for example, the following technologies ar...
