Creating a cluster with luci consists of selecting cluster nodes, entering their passwords, and submitting

the request to create a cluster. If the node information and passwords are correct, Conga automatically

installs software into the cluster nodes and starts the cluster. Create a cluster as follows:

1. As administrator of luci, select the cluster tab.

2. Click Creat e a New Cluster.

3. At the Cluster Name text box, enter a cluster name. The cluster name cannot exceed 15

characters. Add the node name and password for each cluster node. Enter the node name for

each node in the Node Hostname column; enter the root password for each node in the in the

Root Password column. Check the Enable Shared Storage Support checkbox if clustered

storage is required.
