Synchronizing a Remote Replication

Synchronizing a Remote Replication

In the scenario where a remote replication has completed the initial synchronization and then a host writes the primary resource or splits the remote replication, there will be data inconsistency between the primary resource and the secondary resource. In this case, you can synchronize data to ensure data consistency.

Prerequisites

The Pair Running Status of the remote replication determines whether data synchronization can be performed for the remote replication, as shown in Table 3-12.
