Abstract
A managing computer (manager) manages replication of data areas inside a storage or among storages. A storage volume management module of the manager manages policy of the volume and its properties. When replication of a volume is set, a volume of a replication destination appropriate for a volume of a replication source is generated using the policy and the properties to form a replication pair. A route management module of the manager and its volume management module bring the policy and the properties of the volumes, and the policies and conditions of lines into conformity with one another. When any fault occurs in a line route used for data transfer during replication of the volume, a separate line route is utilized, and a fault countermeasure is taken for replication of the volumes in accordance with the policy and properties of the volumes.

18. A storage operation management apparatus for operating and managing replication of a volume inside a storage device or among a plurality of storage devices, said apparatus comprising a processor, a network unit for communication with said storage device, and a managing storage device including a volume management module,
wherein said network unit is adapted for communication between said processor and said storage device, and wherein said processor is adapted, by execution of said volume management module, to receive a request for a copy source volume based on information indicating a feature of said copy source volume; - create or select said copy source volume based on said information;
receive a request for a copy destination volume;
in response to said request for a copy destination volume, create or select said copy destination volume to have said feature of said copy source volume, based on a prestored relationship between said copy source volume and said information, and based on possible/impossible pairing information indicating that said copy destination volume has a pairing capability of forming a replication pair with said copy source volume to make possible the copying of contents of said copy source volume to said copy destination volume, said pairing information being specified by one of a user and an application; and
copy the contents of said copy source volume to said copy destination volume created or selected. - View Dependent Claims (19, 20, 21, 22, 23, 24)

31. A storage operation management apparatus for operating and managing replication of a volume inside a storage device or among a plurality of storage devices, said apparatus comprising a processor, a network unit for communication with said storage device, and a managing storage device including a volume management module,
wherein said network unit is adapted for communication between said processor and said storage device, and wherein said processor is adapted, by execution of said volume management module, to receive a request for a copy source volume based on a feature of said copy source volume, and based on first pairing information indicating a use policy of said copy source volume and indicating that said copy source volume is capable of forming a replication pair with a copy destination volume; - create or select said copy source volume based on said feature and said pairing information;
receive a request for a copy destination volume; and
create or select said copy destination volume to have said feature of said copy source volume, based on said request for a copy destination volume, based on a prestored relationship among said copy source volume and said feature, and based on possible/impossible second pairing information indicating that said copy destination volume has a pairing capability of forming a replication pair with said copy source volume to make possible the copying of contents of said copy source volume to said copy destination volume, said pairing information being specified by one of a user and an application.
- create or select said copy source volume based on said feature and said pairing information;
