Abstract

A storage device, its data processing method and program, and a data processing system. The present invention relates to a storage device in which a logical volume is defined and which enables processing such as logical volume copy to be performed without using environment construction and hardware resources on the host server side. The storage device has: a storage part, ie, a storage part, composed of a recordable storage medium, in which one or more logical volumes are defined; and a storage control part, ie, a storage server, which controls the operation of the storage part. In order to control the operation of the storage section in which the logical volume is defined, management information stored in the database section, ie, the database, is referred to.

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...
