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 (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. 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 removed an Ethernet adapter from the blade server and installed a different Ethernet adapter. 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. Note: The IBM BladeCenter JS20 Fibre Channel Expansion Card (part number 73P6112) must be installed in the blade server. 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 for the blade server to Hard drive 2. 2. Turn on the blade server and establish a Serial Over LAN (SOL) session with the blade server. (See the BladeCenter and BladeCenter T Serial Over LAN Setup Guide for instructions.) 3. Observe the progress codes on the console. When D5BB appears, immediately press the 8 key. The open firmware prompt (>) appears. 4. At the open firmware prompt, enter the following commands: dev /packages/gui setup-fcp-disk The open firmware Main Menu appears. Chapter 5. Configuration requirements for the blade server 39

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
(
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.
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
removed
an
Ethernet
adapter
from
the
blade
server
and
installed
a
different
Ethernet
adapter.
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.
Note:
The
IBM
BladeCenter
JS20
Fibre
Channel
Expansion
Card
(part
number
73P6112)
must
be
installed
in
the
blade
server.
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
for
the
blade
server
to
Hard
drive
2
.
2.
Turn
on
the
blade
server
and
establish
a
Serial
Over
LAN
(SOL)
session
with
the
blade
server.
(See
the
BladeCenter
and
BladeCenter
T
Serial
Over
LAN
Setup
Guide
for
instructions.)
3.
Observe
the
progress
codes
on
the
console.
When
D5BB
appears,
immediately
press
the
8
key.
The
open
firmware
prompt
(>)
appears.
4.
At
the
open
firmware
prompt,
enter
the
following
commands:
dev
/packages/gui
setup-fcp-disk
The
open
firmware
Main
Menu
appears.
