ton. The process is the same as creating a shared resource described in Section 7, "Adding
Cluster Resources". The private resource will appear as a child to the shared resource to
which you associated with the shared resource. Click the triangle icon next to the shared
resource to display any private resources associated.
10. When finished, click OK.
11. Choose File => Save to save the changes to the cluster configuration.

For newly defined clusters, you must propagate the configuration file to the cluster nodes as fol-
lows:
1. Log in to the node where you created the configuration file.
2. Using the command, copy the
scp
Note
Propagating the cluster configuration file this way is necessary for the first
time a cluster is created. Once a cluster is installed and running, the cluster
configuration file is propagated using the Red Hat cluster management GUI
Send to Cluster button. For more information about propagating the cluster
configuration using the GUI Send to Cluster button, refer to Section 3,
"Modifying the Cluster Configuration".
