4.1. Adding an Existing Cluster to the luci Interface

If you have previously created a High Availability Add-On cluster you can easily add the cluster to the luci interface so that you can manage the cluster with Conga.
To add an existing cluster to the luci interface, follow these steps:
  1. Click Manage Clusters from the menu on the left side of the luci Homebase page. The Clusters screen appears.
  2. Click Add. The Add an Existing Cluster screen appears.
  3. Enter the node hostname and root password of any of the nodes in the existing cluster. Since each node in the cluster contains all of the configuration information for the cluster, this should provide enough information to add the cluster to the luci interface.
  4. Click Connect. The Add an Existing Cluster screen then displays the cluster name and the remaining nodes in the cluster.
  5. Enter the individual passwords for each node in the cluster, or enter one password and select Use the same password for all nodes.
  6. Click Add Cluster. The previously-configured cluster now displays on the Manage Clusters screen.
