If you have not done so already, log into the master host as the root user.
Source the settings script. The script you use depends on which shell you are using. The settings are in /gridware/sge/default/common/settings.[sh|csh]. The actual path to these settings depends on where you installed the N1 Grid Engine files.
Run the following command:
gconf -ah proxy_host_name
where proxy_host_name is the name of the N1SM managed server that you want to be the proxy to this Grid. The proxy_host_name must be known by the master host using DNS or the /etc/hosts file.
