Node Conguration
Conguring node IPs
Prior to conguring the individual nodes be sure to verify network and cabling setup has been completed. The
node conguration process conrms connectivity between nodes during IP conguration, as well as the ability
to connect to a gateway before allowing node conguration to continue.
In order to congure your nodes you must have serial or graphical console access to the physical nodes.
Serial access is VT100 at 115,200 baud. Any standard VGA monitor and USB keyboard will work as a graphical
console and are recommended.
Conguration Checklist
Ensure all cables, cords, and switches are setup correctly before conguring the nodes. The following is a check
list to verify before beginning:
• Ensure the system nodes are set up in the same room, with all components next to one another
• Ensure you have connected everything and your equipment (switches, cables, UPS) are appropriate for
your Scale system hardware and everything is powered on
• Have a monitor and keyboard ready and available
Congure the Nodes
All installations should be scheduled at least 24 hours in advance. The installation specialist assisting you will
provide the necessary credentials for command line access during the scheduled installation time.
All conguration of the nodes is done from the command line using a monitor and keyboard. Systems are
congured in a top-to-bottom conguration, with the top node in the rack being the designated “rst” node.
The “rst node” classication has no bearing on system operations outside of the installation conguration.
1. Hook the monitor and keyboard to the top node in the system. Access the node command line using
the provided credentials from the installation specialist.
2. Run the command to begin node conguration: sudo scnodeinit
3. You may be prompted for a password. Use the same password as the node login.
4. You will be prompted for each piece of IP and network information. Once the LAN IP, LAN
Netmask, LAN Gateway, Backplane IP of this node, and Backplane IP of rst node in system
(which will be the same as Backplane IP of this node on the rst node). See below for an example of
NOTE: It is now possible to deploy a Single Node System (SNS). The
commands provided below are applicable to a single node or multiple node
installation. For a single node installation, proceed through Steps 1 to 4, and
then skip to the next chapter, System Initialization.
NOTE: If the login prompt is not shown try pressing SHIFT to disable
console blanking. If the login prompt is still not shown press ctrl+alt+F1
to ensure the correct console session is active.
