Predefining Disaster Recovery Settings for Replications
Predefining DR for a replication restore point is an optional step that configures DR activation settings for a replication restore point ahead
of time, so that the DR site is ready if the destination volume needs to be activated. If you do not intend to access data from a destination
site, you do not need to predefine DR settings. DR settings cannot be predefined for Live Volume restore points.
Predefine Disaster Recovery for Multiple Restore Points
If a pair of Storage Centers host multiple replications, DR settings can be predefined for all of the corresponding restore points
simultaneously.
Steps
1. Click the Replications & Live Volumes view.
2. Click the Restore Points tab, then click Predefine Disaster Recovery. The Predefine Disaster Recovery wizard appears.
3. Select the source/destination Storage Center pair for which you want to predefine DR, then click Next. The wizard advances to the
next page.
4. (Optional) Configure DR settings for each restore point.
a) Select the restore point that you want to modify, then click Edit Settings. The Predefine Disaster Recovery dialog box
appears.
b) Modify the recovery volume settings as needed, then click OK. These attributes are described in the online help.
5. When you are done, click Finish.
Predefine Disaster Recovery Settings for a Single Restore Point
If you need to make sure a recovery site has access to a replicated volume when DR is activated, predefine DR settings for the
corresponding restore point.
Steps
1. Click the Replications & Live Volumes view.
2. Click the Restore Points tab.
3. Right-click the restore point, then select Predefine Disaster Recovery. The Predefine Disaster Recovery dialog box appears.
4. In the Name field, type the name for the recovery volume.
5. Select the server to which the recovery volume will be mapped.
a) Next to the Server label, click Change. The Select Server dialog box appears.
b) Select the server, then click OK.
6. Modify the remaining recovery volume settings as needed. These attributes are described in the online help.
7. Click OK.
Test Activating Disaster Recovery
Testing DR activation for a replication restore point creates a test-activated view volume and maps it to the appropriate server without
interrupting service for the original volume. This allows you to make sure that your DR plan is viable.
• Periodically test-activate DR for restore points to ensure their the restore point is viable.
• DR activation settings specified for test activation are retained for future DR activation and test activation.
• Live Volume restore points cannot be tested.
Test DR Activation for Multiple Restore Points
If a pair of Storage Centers host multiple replications, all of the corresponding restore points can be tested simultaneously.
Prerequisites
• The restore points must be associated with replications. Live Volume restore points cannot be tested.
• The destination volume for each replication must be present on the remote Storage Center. If the destination volume for a replication
restore point is missing, it cannot be tested.
• A server must be present at the DR site to perform test activation.
