Performing a Primary/Secondary Switchover for a Replication Consistency Group (Deprecated)

Function

This API is used to perform a primary/secondary switchover for a replication consistency group. A switchover can be performed to switch the primary and secondary AZs of a replication consistency group, which means that the original secondary AZ will be switched to function as the primary AZ, and original DR ECSs and DR disks will be enabled.

After the primary/secondary switchover, the replication_status value of the replication consistency group is active. At this time, the data between production disks and DR disks in the primary and secondary AZs is consistent in real time, and EVS replication is working normally.

This API has been deprecated. To use this function, see Storage Disaster Recovery Service API Reference.

Constraints

The data synchronization of the replication consistency group is complete, and the replication consistency group is working normally.
