Patent ID: 8234474

Claim:
A management computer, for use in a context wherein one or more host computers and one or more storage apparatuses communicate with each other via a first network, and wherein the one or more host computers and the one or more storage apparatuses communicating with the management computer via a second network, the management computer configured to acquire an application configuration information identifying via the second network, a volume of one of the storage apparatuses used by an application in the host computer, the management computer further configured to create management computer application configuration information identifying a volume of one of the storage apparatuses used by the host computer, using the acquired application configuration information, and configured to store the created management computer application configuration information in a memory unit, the management computer configured to acquire information on an unused volume in each of the storage apparatuses via the second network from each of the storage apparatuses, the management computer configured to create volume configuration information in which the created management computer application configuration information and the acquired information on the unused volume is arranged, and configured to store the created volume configuration information in the memory unit, the management computer configured to create a configuration definition of a copy pair including an original volume into which data in the host computer is written and a duplicated volume into which data is copied, and configured to store the copy pair configuration definition in the memory unit, and the management computer configured to select, upon specification of a group constituted by a plurality of applications as a copy source by an input unit, a volume used by the specified group without duplication by referencing the volume configuration information, and configured to determine the selected volume as a copy source volume, also configured to determine the unused volume as a copy destination volume, and configured to create copy pair configuration definition information associating the copy source volume with the copy destination volume.
