A storage system connected to a computer and a management computer, includes storage devices accessed by the computer, and a control unit for controlling the storage devices. A first-type logical device corresponding to a storage area set in at least one of the storage devices and a second-type logical device that is a virtual storage area are provided. The control unit sets at least two of the first-type logical devices different in a characteristic as storage areas included in a storage pool through mapping. The first-type logical device stores data by allocating a storage area of the second-type logical device to a storage area of the first-type logical device mapped to the storage pool. The characteristic of the second-type logical device can be changed by changing the allocated storage area of the second-type logical device to a storage area of another first-type logical device. |
