Add Host Names to Gridhosts

If you use SAS High-Performance Computing Management Console to manage your cluster, you must add the host names for the additional machines to the /etc/gridhosts file. You can do this with a text editor, or you can use the Gridhosts File Management feature in the console. If you do not use the console for managing the cluster, then you do not need to perform this task.
If you use the console to add the hosts, make sure that the SSH Connectivity column indicates Yes for all the machines. The following display shows an example.

A No in the SSH Connectivity column indicates that passwordless SSH for the root user ID is not configured properly for the machine identified in the Node Name column.
