Patent ID: 7373476

Claim:
A storage system configuration management method executed by a management computer, for detecting a mismatch between management ranges of a first storage area set inside a storage system, and a second storage area in a management range of a user set inside the management computer, a plurality of host computers connected to the storage system, the first storage area being constituted by RAID structure units each formed by an aggregate of a plurality of storage area units, and the second storage area in the management range of the user being managed by logical volume units including a plurality of the storage area units, the method comprising: when identifiers of a plurality of the storage area units are designated as managed objects, obtaining an identifier of at least one of the RAID structure units to which the designated plurality of storage area units belong; referencing an identifier of a user whose management range is at least one of the RAID structure units, and determining whether or not the RAID structure unit obtained at the obtaining step is in the management range of the same user; and when the obtained RAID structure unit is partitioned into management ranges of a plurality of users, outputting the determination result; wherein the management range of a host computer does not correspond to the management range of the user using the host computer.
