Abstract
A storage system according to the present invention includes multiple real storage subsystems, and defines a virtual storage subsystem composed of resources included in one or multiple real storage subsystems. Upon defining a virtual storage subsystem, a virtual logical partition corresponding to a real storage subsystem is provided in the virtual storage subsystem, and a logical partition correlation information which is attribute (limitation) information showing whether various resource management operations extending over virtual logical partitions can be executed or not to each pair within the multiple virtual logical partitions is created and managed. When a management operation instruction regarding the virtual storage subsystem is received, if the resources being the operation target based on the management operation instruction belong to multiple virtual logical partitions, whether resource operation can be executed or not is determined based on the logical partition correlation information, and management operation is limited thereby.
