Storage System Managing Method and Computer System

Abstract

A management server includes the user management segment information having stored therein a volume managed by a user, a receiving unit for receiving a volume allocation request from a management computer, a sending unit for sending the volume allocation request to a storage system and an updating unit for updating the user management segment information based on the information on the allocated volume received from the storage system. The storage system includes a unit for receiving the volume allocation request from the management server, and based on the volume allocation request, allocating the volume from the unallocated volume that can be allocated by all the users.

1 . A storage system management method for managing a volume held by a storage system to store data, the storage system having user management information storing information on a volume that can be allocated by each user, the method comprising the steps of:
 receiving a volume allocation request including information on a user and on a computer from an external system:   allocating, based on said volume allocation request, a volume to said computer from the unallocated volume of said storage system that can be allocated by all the users; and   registering the volume allocated in said user management information as a volume to be managed by the user of said user information.
