Figure: Adding a node to a two-node cluster using two switches shows that before you configure a new system on an existing cluster, you must physically add the system to the cluster.
Connect the VCS private Ethernet controllers.
Perform the following tasks as necessary:
When you add nodes to a two-node cluster, use independent switches or hubs for the private network connections. You can only use crossover cables for a two-node cluster, so you might have to swap out the cable for a switch or hub.
If you already use independent hubs, connect the two Ethernet controllers on the new node to the independent hubs.
Figure: Adding a node to a two-node cluster using two switches illustrates a new node being added to an existing two-node cluster using two independent hubs.
