Performing a Primary/Secondary Switchover

This section describes how to switch the roles of primary and secondary resources of a remote replication pair. The data synchronization direction changes as the primary/secondary relationship changes.

Prerequisites

The remote replication pair for which you want to perform a primary/secondary switchover has not been added to a consistency group.
A primary/secondary switchover can be performed on an asynchronous remote replication pair when the following requirements are met:
Running Status is Split, Secondary Resource Data Status is Consistent, and Secondary Resource Protection is Read and write.
A primary/secondary switchover can be performed on a synchronous remote replication pair when the following requirements are met:
- Running Status is Normal, Secondary Resource Data Status is Synchronized, and Secondary Resource Protection is Read-only.
- Running Status is Split, Secondary Resource Data Status is Consistent, and Secondary Resource Protection is Read and write.

Procedure

Choose Data Protection > Protection Entity > Volume > Remote Replication Pair.
Click More on the right of the desired remote replication pair and select Primary/Secondary Switchover.
Confirm your operation as prompted.
