Perform this task to switch the primary and secondary roles for the block devices in an async remote replication pair.
This task is applicable only to replication pairs in Split state.
Before performing a primary/secondary switchover on a pair, disable secondary block device protection for the pair.
After performing a primary/secondary switchover on a pair, enable secondary block device protection for the pair.
A misoperation might cause the data of the original primary storage volume to be overwritten by the data of the original secondary storage volume. Before performing a primary/secondary switchover, verify that the asynchronous remote replication pair is correct and a role switchover is required.
Select Storage Disaster Recovery from the navigation pane.
Click the Async Remote Replication tab.
Select one or multiple pairs, and then click More Actions > Primary/Secondary Switchover.
