Blade Server Ethernet Controller Enumeration; Configuring The Blade Server For Fibre Channel Boot - IBM JS20 - BladeCenter - 8842 Installation And User Manual

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 your 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 Ethernet expansion card that is installed. 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
3. Enable only one of the Ethernet-controller ports on the blade server. Note the
4. Ping an external computer on the network connected to the Ethernet switch
Communications from optional Ethernet adapters and other I/O expansion cards are
routed to I/O bays 3 and 4. You can verify which controller port on an expansion
card is routed to which I/O bay by performing the same test, using a controller on
the expansion card and a compatible switch module or pass-thru module in I/O bay
3 or 4:

v If you have installed an I/O expansion card on the blade server.

Configuring the blade server for Fibre Channel boot

If you plan to set up your system configuration for remote startup (boot) operations
through Fibre Channel switch modules, you must configure the blade server for
Fibre Channel boot.

Complete the following steps to configure the blade server for Fibre Channel boot:
1. From the management-module Web interface, set the startup (boot) sequence
