ABSTRACT:
A logical volume management apparatus includes a first storage unit that stores configuration information on a first stage logical volume, and a second storage unit that stores configuration information on a second stage logical volume. An access unit finds a storage area in the second stage logical volume that corresponds to the first stage logical volume, and accesses a storage area in a storage device that corresponds to the determined storage area. A logical volume generation unit generates a new second stage logical volume, and a storage area extension unit extends a storage area of the first stage logical volume stored in the configuration information on the first stage logical volume to a desired storage capacity, and makes the new second stage logical volume generated by the logical volume generation unit correspond to the first stage logical volume.
