Abstract
Access to a plurality of logical devices is enabled regardless of the number of ports provided in a storage system and the number of logical devices that can be allocated to a single port, thereby improving the usability of the logical devices. A storage system comprises a plurality of logical devices, a target device which is the object of access from a computer, and a juke box system for allocating one of the plurality of logical devices to the target device. The juke box system changes the logical device that is allocated to the target device in accordance with a request from the computer.
