摘要： In a storage system having a plurality of control units each connected with a plurality of disk units, it is provided that a replication is created in the volume of the disk units connected to different control units. The replication creation unit of a given control unit creates a replication in the volume of the disk unit connected to other control units in such a manner that the original volume information, the replication volume information in the control unit and information on the other control units are registered as volume pair information. Based on this volume pair information, a replication creation request is transmitted to the other control units.
摘要翻译：在具有多个控制单元的存储系统中，每个控制单元各自与多个盘单元相连，条件是在连接到不同控制单元的盘单元的卷中创建复制。给定控制单元的复制创建单元以连接到其它控制单元的盘单元的卷的形式创建复制，使得原始卷信息，控制单元中的复制卷信息和关于其他控制单元的信息是注册为卷对信息。基于该卷对信息，将复制创建请求发送到其他控制单元。

摘要： For a storage system having plural control units to which plural disk devices are connected, in the method for creating replication in a volume of the disk devices connected to different control units, when receiving update I/O of a replication source during an initial copy for replication, the reflection of update to the replication destination is performed on an extension of the same I/O. When a pair is divided after the completion of copying, the update position is retained on the differential bitmap disposed in the individual control units, and the differential bitmap is merged to one of the control units at a time of resynchronization to perform copy processing.
