Abstract
The object of the invention is to control the power consumption in a storage subsystem. In a storage system, when a monitor in a host computer acquires information concerning a storage region to manage the storage region, a monitor in the host computer checks whether or not the power supply state in the storage region is 'on' based on a storage region information that stores first information indicating whether or not the power supply state in the storage region is 'on' and second information concerning the storage region, and acquires the second information from the storage region information table if the power supply state in the storage region is not ‘on’.
