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 Create 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.
4. Click Submit. Clicking Submit causes the following actions:
a. Cluster software packages to be downloaded onto each cluster node.
b. Cluster software to be installed onto each cluster node.
c. Cluster configuration file to be created and propagated to each node in the cluster.
d. Starting the cluster.
A progress page shows the progress of those actions for each node in the cluster.
When the process of creating a new cluster is complete, a page is displayed providing a
configuration interface for the newly created cluster.

3.4. Global Cluster Properties

can configure cluster-wide properties with the tabbed interface below the cluster name. The interface
provides the following tabs: General, Fence, Multicast, and Quorum Partition. To configure the
parameters in those tabs, follow the steps in this section. If you do not need to configure parameters in
a tab, skip the step for that tab.
