It is recommended to test each cluster resource as it is created. This helps to identify misconfigurations or other issues early in the cluster creation process.
In the LifeKeeper User Interface, right-click a resource on the standby node and select “In Service…” from the context menu. This forces a switchover to the standby node.
Once the switchover is confirmed, LifeKeeper will switch the resource (including any dependent resources) to the standby node.
Once the switchover has completed successfully, node-b will be listed as the active node.
