Abstract:
1. A computer system comprising: a plurality of storage systems each including a controller and a logical volume configured by a plurality of physical disk drives coupled to the controller; a virtualization unit coupled to the plurality of storage systems and providing a plurality of virtual volumes configured by a plurality of logical volumes of the plurality of storage systems for a computer as access targets; and a management unit managing a plurality of storage classes each including at least one of the plurality of virtual volumes and related to an action executed for the at least one of the plurality of virtual volumes after migration, wherein when the management unit receives migration information which specifies a source virtual volume and a destination storage class selected from the plurality of storage classes, the management unit selects a destination virtual volume based on the destination storage class, wherein the destination virtual volume is included in both of the destination storage class related to a first action and another storage class related to a second action different from the first action, wherein data of the source virtual volume are migrated from a source logical volume related to the source virtual volume to a destination logical volume related to the destination virtual volume wherein the at least one of the plurality of virtual volumes is selected according to a policy stored in the management unit, and wherein after migration of the data from the source logical volume to the destination logical volume, the first action related to the destination storage class is selected and executed for the destination virtual volume.
