This section describes how to synchronize all remote replication pairs in a consistency group. After the synchronization, the local data and remote data in each remote replication pair are consistent at the synchronization time point, ensuring data validity.
Prerequisites
- This operation can be performed only on the primary device of a remote replication consistency group.
- Secondary resource protection has been enabled.
- Running Status of the remote replication consistency group supports synchronization. Table 1 describes in which status a remote replication consistency group can be synchronized.

Procedure
- Choose Data Protection > Protection Entity > Protection Group > Remote Replication Consistency Group.
- Select one or more desired remote replication consistency groups and click Synchronize.
You can also click More on the right of a desired remote replication consistency group and select Synchronize.
- Confirm your operation as prompted.
