    摘要: There is provided a data migrating method including the steps of: calculating, in a case where data stored in a volume is migrated to another volume, a required period of time for migrating the data based on a size of data to be migrated and volume configuration information on the volume in which the migrated data is stored and the volume to which the data is to be migrated; determining a start time at which the data migration starts to generate a volume migration plan; setting a priority of the generated volume migration plan; prioritizing, in a case where a periods of time during which the generated volume migration plan is executed and a period of time during which an existing volume migration plan is executed are overlapped with each other, and changing the start time of at least one of those volume migration plans having a lower priority.

    摘要: A computer system of the present invention selects and executes an appropriate action in a case where capacity of a pool that provides a real storage area to a virtual logical volume is insufficient. A management computer determines, based on a utilization status of each pool, whether or not there exists a prescribed pool that requires pool size expansion. The management computer, in a case where the prescribed pool is detected, selects at least any one of a volume addition method for adding an unused real volume to the prescribed pool and a data migration method for migrating data of the virtual logical volume to another pool other than the prescribed pool, and expands a pool size of the prescribed pool in accordance with the selected method.

    摘要: The load of managing a storage system is lessened. In a storage system where multiple logical volumes are included in a logical volume group and a copy of the logical volume group is made in a pool area different from the one to which the logical volume group belongs, a management computer adds to the pool area capacity when the capacity of a pool area exceeds a predetermined threshold. When the pool area includes multiple logical volume groups, the management computer requests the storage system to create a pool area for each of the logical volume groups and to create the logical volume groups respectively for the created pool areas. When the pool area includes one logical volume group, the management computer requests the storage system to make the capacity of the pool area coincide with the capacity of a pool area to which the logical volume group is copied.
