Changing the configuration of cluster nodes

As the system administrator of a PowerHA® SystemMirror® cluster, you may need to perform any of several tasks relating to cluster nodes.

Adding nodes to a resource group
Once you have added the new node to the cluster topology, you can continue by adding the new node (or nodes) to the list of participating nodes in a resource group.
Removing a cluster node from the PowerHA SystemMirror configuration
You can remove a node from an active cluster dynamically. However, before removing a node from the cluster, you must remove the node from any resource groups it participates in and synchronize resources.
Changing the name of a cluster node
When changing the name of a cluster node, you must stop cluster services, make the change, and then restart cluster services to apply it to the active configuration.
