Abstract:
1. A management apparatus for managing a computer system including a plurality of storage apparatuses disposed in a plurality of sites, for virtually providing a virtual storage apparatus to a host system over the plurality of storage apparatuses, each of the plurality of storage apparatuses having a logical volume as a virtual volume of the virtual storage apparatus, the management apparatus comprising: a storage apparatus grouping unit configured to group the respective storage apparatuses constituting the virtual storage apparatus into a plurality of storage groups in accordance with a designated grouping policy such that storage apparatuses disposed at an identical subnetwork are grouped as an identical storage group, and assign, to each of the plurality of storage apparatuses, a group ID specific to a storage group, to which a relevant storage apparatus belongs and a copy pair setting unit configured to set a copy pair, for switching a part or whole of each of logical volumes, which are associated with the respective virtual volumes designated as a copy source virtual volume and a copy destination virtual volume of the copy pair, to an appropriate logical volume as necessary based on the group ID assigned to each storage apparatus and in accordance with a designated copy pair setting policy related to a relationship between the copy source virtual volume and the copy destination virtual volume, wherein the copy pair setting policy includes information on local copy or remote copy of the respective logical volumes associated with the copy source virtual volume and the copy destination virtual volume; wherein the grouping policy includes at least one of a first grouping policy to group the storage apparatuses based on product information, a second grouping policy to group the storage apparatuses based on access information retained by each storage apparatus about access from the host system, a third grouping policy to group the storage apparatuses based on network information, and a fourth grouping policy to group the storage apparatuses manually; wherein the storage apparatus grouping unit is configured to: display a grouping policy selection screen for selecting one grouping policy from selectable grouping policies among the first to fourth grouping policies; and group the storage apparatuses in accordance with the grouping policy selected by using the grouping policy selection screen.
