Abstract
The method of the present invention includes the steps of: receiving a command for creating a snapshot of the logical volume; preparing a management table for managing the snapshot; detecting the storage status of the logical volume; and updating the management table without recalling the logical volume from the second level storage to the first level storage when the logical volume has migrated from the first level storage to the second level storage. After the update, the storage table indicates whether creation of a snapshot is required, whether a logical volume has migrated, and whether the second level storage is the storage location of the logical volume.
