20090043960 | Virtual library apparatus, virtual library system, and logical volume copying method - A virtual library apparatus emulates a library apparatus by storing a logical volume on a cache disk. The library apparatus has a first storage medium and a second storage medium. The virtual library apparatus includes a disk volume, a determining unit, a monitor, and a copying unit. The disk volume forms the cache disk. The determining unit determines the logical volume to be copied. The monitor monitors access load to the disk volume and selects the disk volume having the smallest access load on the basis of the monitoring result. The copying unit copies the determined logical volume from the first storage medium to the selected disk volume, and copies the copied logical volume from the disk volume to the second storage medium. | 02-12-2009 |
20090063770 | STORAGE CONTROL APPARATUS, STORAGE CONTROL PROGRAM, AND STORAGE CONTROL METHOD - A storage control apparatus controls a logical volume using a plurality of recording media. The storage control apparatus includes: a management database that manages information of the recording media, type of the logical volume using the recording media, and state of the logical volume, and a control section that sets, when receiving a first instruction of changing a non-mirrored volume set in advance in the management database to a mirrored volume, the non-mirrored volume as a mirrored volume in a non-redundant state which is a state where only one of recording media constituting a mirroring pair exists, in the management database and performs rebuild processing of the mirrored volume in the non-redundant state. | 03-05-2009 |
20110099346 | APPARATUS AND METHOD FOR CONTROLLING STORAGE SYSTEM - In a storage control apparatus, a first duplication control unit causes a logical volume in a disk array device to be copied to a secondary storage medium. A second duplication control unit causes the logical volume to be copied also to an export storage medium in a library device, in connection with the copying to the primary storage medium by the first duplication control unit, when export attributes indicate that the logical volume copied by the first duplication control unit is supposed to be exported. A medium ejection control unit causes the library device to eject the export storage medium, in response to an ejection request therefor. | 04-28-2011 |
