Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 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 gro…
