Adding A Member To A Running Cluster - Red Hat CLUSTER SUITE FOR ENTERPRISE LINUX 5.1 Configuration Manual

Creating a cluster consists of selecting a set of nodes (or members) to be part of the cluster.

follow the steps in this section. The starting point of the procedure is at the cluster-specific page
that you navigate to from Choose a cluster to administer displayed on the cluster tab.

causes the display of an Add a Node element and a Configure element with a list of the
nodes already configured in the cluster.
2. Click a link for a node at either the list in the center of the page or in the list in the detailed
menu under the clusters menu. Clicking a link for a node causes a page to be displayed for

level.
