Incorporating External NICs HowTo

6. Determine which modelmap variable assignment line applies to your needs:
The lines that begin with the string Ethernet are provided for systems that use Gigabit
Ethernet for the Interconnect switch.
The lines that begin with the string !Ethernet are provided for systems that use an
interconnect other than Gigabit Ethernet.
Determine the line that corresponds to the final number of Ethernet devices for the node.
7. Change the text in the External column accordingly:
• If the entry in the External column is offboard, change that text to the PCI bus ID of
the first added NIC.
After:Before:
06:01.0offboard
If there is more than one NIC, add a comma character (,) then enter the PCI bus ID of
the next added NIC. For example:
After:Before:
06:01.0,06:01.1offboard
Repeat as necessary.
IMPORTANT: The list to specify multiple PCI bus IDs must be a comma-separated list
without space characters.
• If there already is a PCI bus ID in the External column, append a comma character (,)
to that value then enter the PCI bus ID of the first added NIC. For example:
After:Before:
03:01.0,06:01.003:01.0
If there is more than one card, add another comma then enter the PCI bus ID of the next
added NIC. For example:
After:Before:
03:01.0,06:01.0,06:01.103:01.0
NOTE: You will need to change the External column of the corresponding line if you
change the interconnect switch from Gigabit Ethernet to another interconnect or vice versa.
8. Double-check your entries.
