The storage subsystem including volumes storing data requested by the host computer, the management computer being accessible to the host computer and the storage subsystem. The copy pair monitoring includes obtaining every piece of copy pair definition information that is stored in the host computer, removing duplicate copy pair definition information from the whole copy pair definition information obtained, and collecting the copy pair status based on the obtained copy pair definition information from which duplicate copy pair definition information has been removed. Each host computer is assigned a priority level, and, when more than one host computer includes the same copy pair, the host computer with the lowest priority obtains the copy pair information to reduce the load on the higher priority host computers. |
