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 on which you want to perform a primary/secondary switchover has not been added to a CG.
- A primary/secondary switchover can be performed on a synchronous remote replication pair when the following requirements are met:
- Running Status is Split, Secondary Resource Data Status is Synchronized, and protection for secondary resource is enabled.
- Running Status is Split, Secondary Resource Data Status is Consistent, and protection for secondary resource is disabled.
- 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 protection for secondary resource is disabled.
Procedure
- Choose Data Protection > Protection Entities > LUNs > Remote Replication Pairs.
- Select the remote replication pair on which you want to perform a primary/secondary switchover and click Primary/Secondary Switchover.Confirm your operation as prompted.
Alternatively, perform any of the following operations to perform a primary/secondary switchover on a remote replication pair:
- Click More on the right of the desired remote replication pair and select Primary/Secondary Switchover.
- Click the name of the desired remote replication pair. In the upper right corner of the page that is displayed, click Operation and select Primary/Secondary Switchover.
- Choose Services > Block Service > LUNs. Click the name of the desired LUN. On the page that is displayed on the right, click the Protection tab, and then select Remote Replication from the drop-down list. Select the desired remote replication pair and choose More > Primary/Secondary Switchover.
- Choose Data Protection > Protection Entities > LUNs > LUNs.
- Click the name of the desired LUN. On the page that is displayed on the right, click the Protection tab, and then select Remote Replication from the drop-down list. Select the desired remote replication pair and choose More > Primary/Secondary Switchover.
- If the value of Remote Replication Pairs is not 0, click the value. Select the desired remote replication pair and choose More > Primary/Secondary Switchover.
