    • 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.
    • 提供了一种数据迁移方法,包括以下步骤:在存储在卷中的数据被迁移到另一卷的情况下,基于要迁移的数据的大小和卷配置来计算迁移数据所需的时间段 存储迁移数据的卷的信息以及要迁移数据的卷; 确定数据迁移开始的开始时间以生成卷迁移计划; 设置生成的卷迁移计划的优先级; 在执行生成的卷迁移计划的时间段和执行现有卷迁移计划的时间段彼此重叠的同时,改变其中的至少一个的开始时间, 卷迁移计划具有较低的优先级。

    • A management computer monitors an allocated capacity of a source virtual volume and an allocated capacity of a virtual pool having a storage area allocated to a destination virtual volume in a storage, judges whether the allocated capacity of the source virtual volume can be covered in the virtual pool or not, and informs the user of a result that data migration fails when the allocated capacity of the source virtual volume cannot be covered. When the allocated capacity of the source virtual volume cannot be covered, the management computer uses another storage area to increase the capacity of the virtual pool. Accordingly, when data migration is performed between the virtual volumes, capacities of physical areas allocated to the source virtual volume and the destination virtual volume can be grasped so that the data migration can be performed accurately between the source virtual volume and the destination virtual volume.
    • 管理计算机监视分配的源虚拟卷的容量和具有分配给存储器中的目的地虚拟卷的存储区域的虚拟池的分配容量,判断虚拟卷中的分配容量是否可以被覆盖 池,并且当源虚拟卷的分配容量不能被覆盖时,通知用户数据迁移失败的结果。 当不能覆盖源虚拟卷的分配容量时,管理计算机使用另一个存储区来增加虚拟池的容量。 因此,当在虚拟卷之间执行数据迁移时,可以掌握分配给源虚拟卷的物理区域的容量和目的虚拟卷,从而能够在源虚拟卷和目的地虚拟卷之间准确地执行数据迁移。
