Patent ID: 8612776

Claim:
A storage control apparatus comprising: an interface device coupled to a plurality of physical storage devices that include at least two encryption devices that are at least two physical storage devices that are configured to include an encryption function and at least two unencryption devices that are at least two physical storage devices that are not provided with an encryption function; and a controller that is configured to be coupled to the interface device, wherein: the controller is configured to store a device attribute that indicates whether a physical storage device that is made to be a basis of a pool of a creation target is an encryption device or an unencryption device as a pool attribute for the pool, the pool configured to include encryption and unencryption devices; when a pool attribute that has been stored for a pool with which a virtual volume that is a virtual logical volume of a creation target is associated indicates both of an encryption and an unencryption, the controller is configured to associate the virtual volume of the creation target with a physical storage device that is configured to conform to an attribute indicating encryption or unencryption and that is specified as a volume attribute of the virtual volume of the creation target among an encryption device and an unencryption device that are a basis of a pool of an associated destination such that a virtual volume that is a storage area is created; and the controller is configured to store a volume attribute of the virtual volume of a creation target.
