This operation enables you 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 shows in which status a remote replication consistency group can be synchronized.
