ReprotectDiskReplicaGroup - Elastic Compute Service - Alibaba Cloud Documentation Center

Enables the reverse replication feature for replication pairs that belong to a replication pair-consistent group. After reverse replication is enabled, data stored on the original secondary disks is replicated to the original primary disks. When a reverse replication is being performed, the primary and secondary sites of the replication pair-consistent group remain unchanged, but data is replicated from the secondary site to the primary site.

Operation description

Usage notes

For information about the regions in which the replication pair-consistent group feature is available, see Overview .
The replication pair-consistent group for which you want to enable reverse replication must be in the Failovered (failovered) state. You can call the FailoverDiskReplicaPair operation to enable failover.
Before a reverse replication is performed, the primary disks must be detached from its associated Elastic Compute Service (ECS) instance and must be in the Unattached state. You can call the DetachDisk operation to detach the disks.
After you enable reverse replication, you must call the StartDiskReplicaPair operation again to enable the async replication feature before data can be replicated from the original secondary disks to the original primary disks.
You can set the ReverseReplicate parameter to false to cancel the Failovered (failovered) state and restore the original replication direction.
