Abstract

A subsystem logics partitioning and managing apparatus comprises a recognition unit for recognizing logical and physical resources that constitute a subsystem a partition definition table in which the logical and physical resources in the subsystem are assigned for each user at an interface level at which a storage configuration can be referenced by a storage management program an account table in which an account is set for each user-specific partition defined in the partition definition table a receiving unit for receiving a user account transmitted from an information processing unit and checking the received user account against the account table, to recognize a partition that corresponds to the user and a unit for outputting, at a GUI level, logical resources and physical resources that are contained in the recognized partition to an output interface as a resource configuration in the subsystem.
