Abstract
An administrator's work load increases because the administrator has to both allocate volumes of PC server device applications and take over volumes for applications based on changes in PC server devices. A volume management system solves the problem with a computer system having storage devices each having a unit managing volume configuration information based on each application, a unit managing volume usage information based on the application volumes, and a unit managing and partitioning allocatable areas of the storage devices based on performance and reliability. The system has a unit selecting suitable allocation regions in accordance with the volume usages of the applications; a unit selecting a suitable allocation region based on change of host performance and migrating a volume to the suitable allocation region when the host configuration of an application changes; and a unit changing configuration information to perform change of setting on each host.
