MANAGEMENT APPARATUS AND MANAGEMENT METHOD

摘要

A management apparatus and management method capable of simplifying system management and constructing copy pairs with fault tolerance intended by a user are suggested. With a computer system for providing a host system with logical volumes in the system respectively as virtual volumes in one virtual storage apparatus, each storage apparatus is grouped in accordance with a designated grouping policy and a group ID specific to a storage group, to which the relevant storage apparatus belongs, is assigned to each storage apparatus; and when setting a copy pair, a part or whole of each logical volume is switched to an appropriate logical volume as needed in accordance with a copy pair setting policy, including a location relationship of the respective logical volumes associated with the respective virtual volumes constituting the copy pair, based on the group ID of each storage apparatus.
