traffic switches back to the primary Ethernet controller port. (See the
operating-system device driver documentation for information about configuring for
failover.)
Important: To support failover on the blade server Ethernet controller, the Ethernet
switch modules in the BladeCenter unit must have identical configurations to each
other.
Blade server Ethernet controller enumeration
The enumeration of the Ethernet controllers or controller ports in a blade server is
operating-system dependent. You can verify the Ethernet controller or controller port
designations that a blade server uses through the operating-system settings.
The routing of an Ethernet controller or controller port to a particular BladeCenter
unit I/O bay depends on the type of blade server. You can verify which Ethernet
controller port in this blade server is routed to which I/O bay by using the following
test:
1. Install only one Ethernet switch module or pass-thru module in I/O bay 1.
2. Make sure that the ports on the switch module or pass-thru module are enabled
( I/O Module Tasks → Management → Advanced Management in the
BladeCenter management-module Web interface).
3. Enable only one of the Ethernet controller ports on the blade server. Note the
designation that the blade server operating system has for the controller port.
4. Ping an external computer on the network connected to the Ethernet switch
module. If you can ping the external computer, the Ethernet controller port that
you enabled is associated with the switch module in I/O bay 1. The other
Ethernet controller port in the blade server is associated with the switch module
in I/O bay 2.
If you have installed an I/O expansion card on a blade server, communications from
the option are routed to I/O bays 3 and 4. You can verify which controller port on
the card is routed to which I/O bay by performing the above test, using a controller
on the I/O expansion card and a compatible switch module or pass-thru module in
I/O bay 3 or 4.
