Escala BL460 - Problem Determination and Service Guide
The Ethernet controllers in your blade server support failover, which provides automatic
redundancy for the Ethernet controllers. Failover capabilities vary per Bull Blade Chassis -
Enterprise.
Without failover, only one Ethernet controller can be connected from each server to each
virtual LAN or subnet. With failover, you can configure more than one Ethernet controller
from each server to attach to the same virtual LAN or subnet. Either one of the integrated
Ethernet controllers can be configured as the primary Ethernet controller. If you have
configured the controllers for failover and the primary link fails, the secondary controller
takes over. When the primary link is restored, the Ethernet traffic switches back to the
primary Ethernet controller. See the operating-system device-driver documentation for
information about configuring for failover.

To support failover on the blade server Ethernet controllers, the Ethernet switch modules in
the Bull Blade Chassis - Enterprise must have identical configurations.
5.6 Blade server Ethernet controller enumeration
The enumeration of the Ethernet controllers in a blade server is operating-system
dependent. You can verify the Ethernet controller designations that a blade server uses
through the operating-system settings.
The routing of an Ethernet controller to a particular I/O-module bay depends on the type of
blade server. You can verify which Ethernet controller is routed to which I/O-module bay
by using the following test:
1. Install only one Ethernet switch module or pass-thru module in I/O-module bay 1.
2. Make sure that the ports on the switch module or pass-thru module are enabled. Click
I/O Module Tasks
→
Admin/Power/Restart in the management-module Web
interface.
3. Enable only one of the Ethernet controllers on the blade server. Note the designation
that the blade server operating system has for the controller.
4. Ping an external computer on the network that is connected to the switch module or
pass-thru module. If you can ping the external computer, the Ethernet controller that
you enabled is associated with the switch module or pass-thru module in I/O-module
bay 1. The other Ethernet controller in the blade server is associated with the switch
module or pass-thru module in I/O-module bay 2.
If you have installed an I/O expansion card in the blade server, communication from the
expansion card should be routed to I/O-module bays 3 and 4, if these bays are supported
by your Bull Blade Chassis - Enterprise. You can verify which controller on the card is
routed to which I/O-module bay by performing the same test and using a controller on the
expansion card and a compatible switch module or pass-thru module in I/O-module bay 3
or 4.
