To solve this problem, there is provided a volume management system in a computer system having storage devices each of which has a unit which manages volume configuration information in accordance with each application, a unit which manages volume usage information in accordance with each of volumes for the applications, and a unit which manages allocatable areas of the storage devices while partitioning the allocatable areas of the storage devices in accordance with performance and reliability, wherein the volume management system has: a unit which selects suitable allocation regions in accordance with the volume usages of the applications; a unit which selects a suitable allocation region in accordance with change of host performance and migrates a volume to the suitable allocation region when host configuration of an application is changed; and a unit which changes configuration information to perform change of setting on each host. |
