Method of constructing replication environment and storage system

A storage system, comprising:

• one or more host computers;
• one or more storage apparatuses;
• and
• a management computer,
• wherein the one or more host computers and the one or more storage apparatuses communicating with each other via a first network,
• wherein the one or more host computers and the one or more storage apparatuses communicating with the management computer via a second network,
• wherein the management computer acquires an application configuration information on which application in the host computer uses which volume, from each of the host computers via the second network,
• wherein the management computer creates management computer application configuration information on which application in which host computer uses which volume, using the acquired application configuration information, and storing the created management computer application configuration information in a memory unit,
• wherein the management computer acquires information on an unused volume in each of the storage apparatuses via the second network from each of the storage apparatuses,
• wherein the management computer creates volume configuration information in which the created management computer application configuration information and the acquired information on the unused volume is arranged, and stores the created volume configuration information in the memory unit,
• wherein the management computer creates 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 storing the copy pair configuration definition in the memory unit, and
• wherein, upon specification of a group constituted by a plurality of applications as a copy source by an input unit, wherein the management computer selects a volume used by the specified group without duplication by referencing the volume configuration information, determines the selected volume as a copy source volume, also determines the unused volume as a copy destination volume, and creates copy pair configuration definition information associating the copy source volume with the copy destination volume.

• wherein the one or more host computers and the one or more storage apparatuses communicating each with the management computer via a second network,
• wherein the management computer acquires information on a virtual machine in the host computer and a used volume in the virtual machine,
• wherein the management computer creates virtual machine configuration information associating the information on the virtual machine and the used volume acquired by the virtual machine configuration information acquisition unit, and storing the virtual machine configuration information in a memory unit,
• wherein the management computer acquires information on an unused volume from the storage apparatus,
• wherein the management computer creates volume configuration information in which the virtual machine configuration information and the information on an unused volume acquired by the unused volume information acquisition unit is arranged, and storing the created volume configuration information in the memory unit,
• wherein the management computer creates a configuration definition of a copy pair including an original volume into which data in the virtual computer is written and a duplicated volume into which data is copied, and storing the copy pair configuration definition in the memory unit, and
• wherein, upon specification of the virtual machine as a copy source by an input unit, wherein the management computer selects a volume used by the specified virtual machine without duplication by referencing the volume configuration information, determines the selected volume as a copy source volume, also determines the unused volume as a copy destination volume, and creates copy pair configuration definition information associating the copy source volume with the copy destination volume.
