A storage control apparatus comprises a virtualization control part in addition to a copy control part determining whether or not a PVOL (a copy-source VOL) attribute set and a SVOL (a copy-destination VOL) attribute set are the same and carrying out a data copy between VOLs in a case where the result of this determination is affirmative. The virtualization control part creates either a virtual PVOL which is a VOL obtained by virtualizing the PVOL and which comprises the SVOL attribute set, or a virtual SVOL which is a VOL obtained by virtualizing the SVOL and which comprises the PVOL attribute set. As a result, either the VOL attribute set of the virtual PVOL and the SVOL attribute set become the same, or the PVOL attribute set and the VOL attribute set of the virtual SVOL become the same, and the copy control part can thereby carry out a copy between VOLs. |
