摘要： The storage system of the present invention has a simple configuration and ensures redundancy of the system. The primary storage control device and the first secondary storage control device are connected by a synchronous read method, and the primary storage control device and the second secondary storage control device are connected by an asynchronous read method. The primary storage control device sets a management number in the update data and saves a journal data. The primary storage control device associates the management number with the update data and transmits them to the first secondary storage control device. The first secondary storage control device writes the update data to the first secondary volume, associates the management number with the storage destination address of the update data and stores them in the maintenance table. If the primary storage control device stops, the first secondary storage control device becomes anew a primary storage control device. The first secondary storage control device is connected to the second secondary storage control device by an asynchronous read method.

摘要： A storage system maintains consistency of the stored contents between volumes even when a plurality of remote copying operations are executed asynchronously. A plurality of primary storage control devices and a plurality of secondary storage control devices are connected by a plurality of paths, and remote copying is performed asynchronously between respective first volumes and second volumes. Write data transferred from the primary storage control device to the secondary storage control device is held in a write data storage portion. Update order information, including write times and sequential numbers, is managed by update order information management portions. An update control portion collects update order information from each update order information management portion, determines the time at which update of each second volume is possible, and notifies each-update portion. By this means, the stored contents of each second volume can be updated up to the time at which update is possible.
摘要翻译： 即使当多个远程复制操作被异步地执行时，存储系统也保持存储在卷之间的内容的一致性。 多个主存储控制装置和多个辅助存储控制装置通过多个路径连接，并且在相应的第一卷和第二卷之间异步地执行远程复制。 将从主存储控制装置传送到副存储控制装置的写入数据保存在写入数据存储部分中。 更新订单信息（包括写入时间和顺序号）由更新订单信息管理部分管理。 更新控制部分从每个更新订单信息管理部分收集更新订单信息，确定可以更新每个第二卷的时间，并通知每个更新部分。 通过这种方式，可以更新每个第二卷的存储内容直到可能进行更新的时间。

摘要： A storage system comprises a primary storage device having a primary storage area, a first secondary storage device having a first secondary storage area, and a second secondary storage device having a second secondary storage area. Responsive to host request from a host computer, the primary storage device writes requested host data to the primary storage area. Furthermore the primary storage device sends a first and second copy request to the first and second secondary storage devices, respectively, to store copy data in the first and second secondary storage areas, the first and second copy request containing the copy data which is a copy of the host data. Here the second secondary storage area is identified by a virtual identifier used to identify the second secondary storage area as the virtual storage area within the primary storage device.
