Abstract
In a state where one of physical storage regions is allocated to each of unit regions included in a logical storage region, an apparatus identifies, from among the unit regions, first unit regions which have been allocated from physical storage regions whose allocations to the first unit regions are to be changed. The apparatus sequentially selects, from among the first unit regions, a second unit region as a candidate for data migration, and instructs data migration of the second unit region between the physical storage regions. The apparatus determines whether data migration of any one of the unit regions whose data has been instructed to be migrated is being executed on each of multiple divided regions obtained by dividing a physical storage region to which data of the second unit region is to be migrated, and instructs data migration of the second unit region based on the determination.
