Step 2 Choose Data Protection > Remote Replication > Remote Replication Pair.
Step 3 Right-click the remote replication you want to split and choose Split.
The security alert dialog box is displayed.
Step 4 Confirm the remote replication splitting.
1. Confirm the information in the dialog box. Select I have read and understand the
consequences associated with performing this operation. and click OK.
The Success dialog box is displayed, indicating that the operation succeeded.
2. Click OK.

6.5 Performing a Primary/Secondary Switchover for a
Remote Replication
This operation enables you to switch the roles of the primary and secondary resources of a
remote replication pair. The data synchronization direction changes as the primary/secondary
relationship changes.
Prerequisites
l The remote replication pair for which you want to initiate a primary/secondary
switchover is not added to a consistency group.
l Primary/Secondary switchover can be performed when synchronous remote replication
is in the following states:
– Pair Running Status is Normal, Secondary Resource Data Status is
Synchronized, and Status of Secondary Resource Protection is Read-only.
– Pair Running Status is Split, Secondary Resource Data Status is Consistent,
and Status of Secondary Resource Protection is Read/Write.
l Primary/Secondary switchover can be performed when asynchronous remote replication
is in the following states: Pair Running Status is Split, Secondary Resource Data
Status is Consistent, and Status of Secondary Resource Protection is Read/Write.
Procedure
Step 1 Log in to DeviceManager.
Step 2 Choose
Data Protection > Remote Replication > Remote Replication Pair.
Step 3 Right-click the remote replication you want to perform the switchover and choose Primary/
Secondary Switchover.
The security alert dialog box is displayed.
