When migrating a virtual server between a plurality of physical servers, a pre-migration connection relationship between the virtual server and a storage area used by the virtual server is maintained after the migration of the virtual server by using a cooperative mechanism between a plurality of storage apparatuses even if the storage area used by the virtual server is migrated between the plurality of storage apparatuses. A computer system and virtual server migration control method for the computer system is described.

Provided is a method of using a dynamic chunk allocation function to efficiently carry out data volume migration. A storage apparatus according to the present invention includes first and second storage units and divides a storage extent in the second storage unit into chunks to add the chunks to a chunk pool to dynamically allocate the chunks in the chunk pool to a newly created logical data volume (see FIG. 3).

A storage apparatus of an embodiment of the invention including one or more storage drives for providing real storage resources and a controller for controlling the one or more storage drives and accesses from a host computer. The controller initializes real storage resources and manages the initialized real storage resources. The controller receives an instruction for allocating an initialized real storage resource to a first virtual storage resource accessed by the host computer. In response to the instruction, the controller allocates a first initialized real storage resource which has been initialized in advance prior to the instruction to the first virtual storage resource.

It is an object to use a storage region in an efficient manner and maintain a performance of a storage system. A volume group GR11 includes reference volumes 1411, 1413, and 1415 and source volumes 1412, 1414, 1416, and 1417 that derive from the reference volumes. Each of the volumes stores only the difference data from a volume that is a parent thereof. A volume that is a cause of a problem is moved or copied from a pool of the moment 1410 to other pool 1420. A configuration of a volume group is modified.
