Abstract
A storage control apparatus, that controls a storage apparatus that includes a storage drive in which a plurality of logical volumes are set, includes a storage unit that stores load information for each of the plurality of logical volumes, and a control unit that determines to-be-rebuilt volumes, which are targets to be rebuilt, from the plurality of logical volumes, sequentially selects a logical volumes for which a volume-specific taken time is estimated, determines, for each selected logical volume, a volume-specific start time at which a rebuild will be started, estimates, by using the volume-specific start time and the load information about the selected logical volume, the volume-specific taken time for rebuilding the selected logical volume, and totals the volume-specific taken time estimated for each selected logical volume to calculate a total taken time taken for rebuilding the to-be-rebuilt volumes.
