Abstract
An instruction to associate a second logical volume with a second virtual storage, which is a migration destination of a first virtual storage that provides a first logical volume, is transmitted. The first virtual storage is a virtual storage to which a virtual resource provided by a virtual managing unit is allocated. A copy instruction, which is an instruction to copy data from either one of the first logical volume and a copy source logical volume of the first logical volume to the second logical volume is transmitted. When copy completion, which is completion of the data copy to the second logical volume, is detected, an erasing instruction, which is an instruction to erase the first virtual storage, is transmitted to the virtual managing unit.
