摘要：
A primary group may be swapped with a synchronous backup group where triangular asynchronous replication is being provided between the primary group, the synchronous backup group and an asynchronous backup group. Swapping may include halting work at the primary group, transferring pending mirrored data from the primary group to an asynchronous backup group, creating a data mirroring relationship between a storage volume at the synchronous backup group and a storage volume at the asynchronous backup group, reversing a data mirroring relationship between the storage volume at the primary group and the storage volume at the synchronous backup group, and resuming work at the asynchronous backup group.
