ABSTRACT:
A virtual storage system control apparatus, a virtual storage system control program and a virtual storage system control method can move one or more than one virtual volumes without suspending the services being provided. The virtual storage system control apparatus comprises a plurality of storage device control sections that assign virtual volumes to the storage devices of the virtual storage clusters, generate information on the virtual volumes, set up a link between the virtual volumes of the own virtual storage clusters and the virtual volumes of other virtual storage clusters by way of the network and copy data on the basis of the link and a management node that directs a move of a virtual volume by having the link set up according to the information on the virtual volumes.
