摘要

PPROBLEM TO BE SOLVED: To realize the migration of data maintaining WORM attributes. PSOLUTION: A storage device is connected with a computer system through a network and is provided with a controller and a drive unit including a plurality of logical volumes, and updating inhibition information indicating inclusion of an area assigned an updating inhibition attribute is recorded in at least one of the logical volumes. The controller includes a configuration management part that sets the logical volume assigned the updating inhibition attribute as a logical volume of a migration source and another logical volume as a logical volume of a migration destination and sets the updating inhibition information concerning the logical volume of the migration source in the logical volume of the migration destination, and a migration part that copies data of the logical volume of the migration source to the logical volume of the migration destination after the setting of the updating inhibition information concerning the logical volume of the migration source in the logical volume of the migration destination.
