5.5.1. Adding a Member to a Cluster

To add a member to a new cluster, follow these steps:
1. Click Cluster Node.

3. At the Cluster Node Name text box, specify a node name. The entry can be a name or an IP
address of the node on the cluster subnet.
Note
Each node must be on the same subnet as the node from which you are running
the Cluster Configuration Tool and must be defined either in DNS or in the /etc/
hosts file of each cluster node.
Note
The node on which you are running the Cluster Configuration Tool must be explicitly
added as a cluster member; the node is not automatically added to the cluster
configuration as a result of running the Cluster Configuration Tool.
4. Optionally, at the Quorum Votes text box, you can specify a value; however in most
configurations you can leave it blank. Leaving the Quorum Votes text box blank causes the
quorum votes value for that node to be set to the default value of 1.
5. Click OK.
6. Configure fencing for the node:
