Method of creating a logical storage device

摘要

An administrator is required to prepare in advance logical unit as a pool area when a user storage area is set to a storage. Logical unit configuration is generally cumbersome and it is not easy for a general user to configure it. A pool manager 1 (311) and a storage 1 setting utility (321) in a management console 1 (301) communicate with a program in a storage 1 (101). The storage 1 (101) sets a pool area having a designated capacity. In response to a volume forming request from the management console 1 (301), the storage 1 (101) sets a designated volume by setting the designated volume as a used capacity of the set pool area. When a volume is formed, a policy is designated to select a storage area having a corresponding attribute from the pool area.
