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
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
(
I/O
Module
Tasks
>
Management
>
Advanced
Management
in
the
management
module
Web-based
user
interface).
3.
Enable
only
one
of
the
Ethernet
controllers
on
the
blade
server.
Note
the
designation
the
blade
server
operating
system
has
for
the
controller.
4.
Ping
an
external
computer
on
the
network
connected
to
the
switch
module.
If
you
can
ping
the
external
computer,
the
Ethernet
controller
that
you
enabled
is
associated
with
the
switch
module
in
I/O-module
bay
1.
The
other
Ethernet
controller
in
the
blade
server
is
associated
with
the
switch
module
in
I/O-module
bay
2.
If
you
have
installed
an
expansion
card
on
a
blade
server,
communications
from
the
option
are
routed
to
I/O-module
bays
3
and
4,
if
these
bays
are
supported
by
your
BladeCenter
unit
type.
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.
Configuring
a
SCSI
RAID
Note:
Configuring
a
SCSI
RAID
only
applies
to
a
blade
server
that
has
two
SCSI
hard
disk
drives
installed.
You
can
configure
a
SCSI
redundant
array
of
independent
disks
(RAID)
array
for
your
blade
server.
Two
SCSI
hard
disk
drives
in
the
blade
server
can
be
used
to
implement
and
manage
a
RAID
level-1
(mirror)
array
under
operating
systems
that
are
listed
on
the
ServerProven
list
at
http://www.ibm.com/pc/compat/.
For
information
about
this
function,
see
the
Installation
and
User’s
Guide
.
Important:
You
must
create
the
RAID
array
before
you
install
the
operating
system
on
the
blade
server.
