Switching the service group

Before switching the application back to the original primary RDC zone, you must resynchronize any changed data from the active DR site since the failover. This can be done manually through VVR or by running a VCS action from the RVGPrimary resource.

 To switch the service group

1. In the Service Groups tab of the configuration tree, right-click the resource.
2. Click Actions.
3. Specify the details of the action:

• From the Action list, choose fast-failback.
• Click the system on which to execute the action.
• Click OK.

  This begins a fast-failback of the replicated data set. You can monitor the value of the ResourceInfo attribute for the RVG resource to determine when the resynchronization has completed.

4. Once the resynchronization completes, switch the service group to the primary cluster. In the Service Groups tab of the of the Cluster Explorer configuration tree, right-click the service group.
5. Click Switch To and select the system in the primary RDC zone to switch to and click OK.
