Abstract
A storage control apparatus includes a first logical volume in which data has been stored in a pool that includes at least one of one or a plurality of logical volumes based on a plurality of physical storage devices as a pool volume, and divides the first logical volume into at least two real areas. The storage control apparatus allocates the first logical volume to a second logical volume that is a virtual logical volume that has been divided into at least two virtual areas. The storage control apparatus executes a first data movement processing for moving all data of the first logical volume to at least one pool volume other than the first logical volume, and allocates a real area of a movement destination of the data to a virtual area of an allocated destination of a real area of a movement source of the data as substitute for the real area in the first data movement processing.
