Raid-type library apparatus using cartridge storing a plurality of storage media and method for controlling the library apparatus

摘要

There are provided a cartridge transport mechanism that sequentially transports a media cartridge, capable of storing a plurality of storage media, to predetermined positions corresponding to a plurality of library units, and a control device that performs control for passing a predetermined number of the storage medium between the media storage section or drive device of each of the library units and the media cartridge sequentially transported to the predetermined position corresponding to the library unit. As the media cartridge is sequentially transported to the predetermined positions, the library units each receive or send the predetermined number of the storage medium from or to the media cartridge. Because all of the storage media of a same RAID group that are stored or to be stored dividedly in and across the library units can be stored together in a same media cartridge allocated to that RAID group, a user can collectively manage the storage media of each RAID group just through the use of the media cartridge.
