| Summary: | The work load imposed on an administrator increases because the administrator has heretofore performed the work of allocating volumes to applications of PC server devices and the work of taking over volumes for applications in accordance with change in PC server devices. 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. |
