An administrator is required to prepare in advance LU as a pool area when a user
storage area is set to a storage. LU configuration is generally cumbersome and
it is not easy for a general user to configure it. A pool manager 1 and
a storage 1 setting utility in a management console 1 communicate
with a program in a storage 1. The storage 1 sets a pool area having
a designated capacity. In response to a volume forming request from the management
console 1, the storage 1 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.
