ABSTRACT:
A manager is allowed to retrieve management information of a logical volume for which the manager has the management right. A storage system has multiple logical volumes managed by different managers and a controller controlling the multiple logical volumes. The storage system stores first identification information for identifying each of the multiple logical volumes, first management information of a logical volume mapped to the first identification information, and correspondence between the first identification information and manager identification information of a manager having a management right for a logical volume identified by the first identification information. In response to an instruction having manager identification information of a manager in accordance with an input from the manager managing one of the multiple logical volumes, the storage system outputs first management information of a logical volume identified by first identification information mapped to the received manager identification information.
