Node Configuration
Prior to configuring the individual nodes be sure to verify network and cabling setup has been completed. The node
configuration process confirms connectivity between nodes during IP configuration, as well as the ability to connect
to a gateway before allowing node configuration to continue.
In order to configure 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.
Configure the Nodes
All installations should be scheduled at least 24 hours in advance. The ScaleCare engineer assisting you will provide
the necessary credentials for command line access during the scheduled installation time.
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 section, System Initialization.
All configuration of the nodes is done from the command line using a monitor and keyboard. Systems are
configured in a top-to-bottom configuration, with the top node in the rack being the designated 'first' node. The 'first
node' classification has no bearing on system operations outside of the installation configuration.
1. Hook the monitor and keyboard to the top node in the system. Access the node command line using the
provided credentials.
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.
2. Run the command to begin node configuration: 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 first node in system (which will be the same as
Backplane IP of this node on the first node). See below for an example of the first node’s IP configuration.
