摘要： A storage system comprises a storage medium including a plurality of physical storage areas. The storage system controls a host computer to recognize a logical volume having a plurality of virtual storage areas, reads the data from the physical storage area assigned to the virtual storage area of the logical volume, determines whether or not the read data includes only the specific pattern data, and cancels the assignment of the physical storage area to the virtual storage area if the read data includes only the specific pattern data.
摘要翻译： 存储系统包括包括多个物理存储区域的存储介质。 存储系统控制主计算机识别具有多个虚拟存储区域的逻辑卷，从分配给逻辑卷的虚拟存储区域的物理存储区域读取数据，确定读取的数据是否仅包括特定的 模式数据，并且如果读取的数据仅包括特定模式数据，则将物理存储区域的分配取消到虚拟存储区域。
