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.
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.
