Determine Boot Interface and MAC Address

Determines the boot interface and MAC address of an eLogin node, which is information needed to configure the eLogin node for management by the SMW of a Cray XC system.

SMW and network configuration information has been gathered.

This procedure determines the boot interface and MAC address of an eLogin node.

The boot interface depends on the hardware being used. The boot interface is the first 1GbE interface, per one of the following configurations:
  • eth0 on eLogin nodes with the 4x1GbE LOM (LAN on motherboard) network adapter
  • eth2 on eLogin nodes with the 2x10GbE+2x1GbE LOM network adapter
  1. Power up the node.
    When the BIOS power-on self-test (POST) process begins, press the F2 key immediately after the following messages appear in the upper-right of the screen.
    F2 = System Setup
F10 = System Services
F11 = BIOS Boot Manager
F12 = PXE Boot
    Figure: BIOS Config Screen
    When the F2 keypress is recognized, the F2 = System Setup line changes to Entering System Setup.
    After the post process completes and all disk and network controllers have been initialized, the System Setup Main Menu screen appears with the following sub-menus:
    System BIOS
iDRAC Settings
Device Settings
  2. Select Device Settings from the System Setup Main Menu, then press Enter.

  3. Select Integrated NIC 1 Port N ... in the Device Settings window.
    Choose the NIC port number that corresponds to the Ethernet port for the external-management-net network:
    • If external-management-net uses the first Ethernet port (eth0), select Integrated NIC 1 Port 1 ...
    • If external-management-net uses the third Ethernet port (eth2), select Integrated NIC 1 Port 3 ...

  4. Verify that the correct NIC port number is selected, then press Enter to open the Main Configuration Page.
  5. Identify the Permanent MAC Address on the Main Configuration Page screen.
    The following figure shows an example MAC address.

  6. Record the MAC address and the boot interface in the table in SMW, Network, and eLogin Configuration Information.
  7. Press Esc to exit to the Device Settings menu.
  8. Select No when prompted with the "Settings have changed" message, then press Enter.
  9. Press Esc to exit the System Setup Main Menu.
    The System Setup Main Menu screen appears.
  10. Press Esc to exit the System Setup Main Menu.
