OUI fails to display the nodes names on the cluster configuration screen during the installation of Oracle Clusterware

The Oracle Universal Installer (OUI) fails to display the names of the nodes in the cluster on the "Specify Cluster configuration" screen at the time of installing Oracle Clusterware.

The OUI runs the /tmp/OraInstall*/*/lsnodes utility to determine the names of the nodes in the cluster. If the utility fails to retrieve the node information, the node information fails to display in the OUI.
