Storage apparatus and logical volume migration method |
摘要 |
This storage apparatus includes a first logical volume migration unit for migrating the logical volume of a first storage area targeted for power source shutdown to a second storage area that is not targeted for power source shutdown based on an external command, and a second logical volume migration unit for migrating an expiration date-defined logical volume from the second storage area to a third storage area of a post-expiration migration destination when the expiration date of the expiration date-defined logical volume set with an expiration date for migrating the logical volume is reached. The first logical volume migration unit balances and migrates the expiration date-defined logical volume to the second storage area by referring to the expiration date of the expiration date-defined logical volume and taking into consideration the migration timing to the third storage area. |
