Register the newly added servers.
Perform the following procedure on a reference server chosen between already running servers:
Clearing Network Parameter Settings
Execute the rcxadm lanctl unset command to clear the network parameters configuration.
Edit the definition file.
Set up a node entry in the definition file (ipaddr.conf) with the server name, interface entries and other information for the server to be added.
Manually execute network parameter settings
Execute the rcxadm lanctl set command to apply the network parameters and make sure that the resulted configuration (induced from the definition file) is correct.
Collect the cloning image again.
Deploy the collected cloning image to the newly added servers.
Modifying Existing Public LAN Configuration
If network settings must be modified due to the addition or removal a public LAN, or a change of IP address; perform the following on an arbitrary reference server (chosen between already running servers).
Execute the rcxadm lanctl unset command to clear the network parameters configuration.
Edit the definition file to add, modify or delete network parameters.
Execute the rcxadm lanctl set command to apply the network parameters and make sure that the resulted configuration (induced from the definition file) is correct.
