    • A storage control apparatus includes a first logical volume in which data has been stored in a pool that includes at least one of one or a plurality of logical volumes based on a plurality of physical storage devices as a pool volume, and divides the first logical volume into at least two real areas. The storage control apparatus allocates the first logical volume to a second logical volume that is a virtual logical volume that has been divided into at least two virtual areas. The storage control apparatus executes a first data movement processing for moving all data of the first logical volume to at least one pool volume other than the first logical volume, and allocates a real area of a movement destination of the data to a virtual area of an allocated destination of a real area of a movement source of the data as substitute for the real area in the first data movement processing.
    • 存储控制装置包括第一逻辑卷,其中数据已经被存储在基于多个物理存储设备的池卷的一个或多个逻辑卷中的至少一个的池中,并且划分第一逻辑卷 进入至少两个实际区域。 存储控制装置将第一逻辑卷分配给作为被划分为至少两个虚拟区域的虚拟逻辑卷的第二逻辑卷。 存储控制装置执行用于将第一逻辑卷的所有数据移动到除了第一逻辑卷之外的至少一个池卷的第一数据移动处理,并且将数据的移动目的地的实际区域分配给虚拟区域 在第一数据移动处理中将数据的移动源的实际区域的分配目的地替换为实际区域。
