What Is the Impact of the Secondary Storage System Failure on Remote Replication?
Question
What is the impact of the secondary storage system failure on remote replication?
Answer
If the secondary storage system is powered off or faulty, services running on the primary storage system are not affected but the remote replication relationship is interrupted. The primary storage system records changes after the remote replication relationship is interrupted in a Data Change Log (DCL). After the secondary storage system is recovered, the remote replication relationship can be restored by data synchronization.
