Chapter 5. Configuration requirements for the blade server This chapter contains the configuration tasks that you must perform so that you can run Serial Over LAN (SOL) sessions on the blade server and use the IBM BladeCenter management-module command-line interface. This chapter also describes other configuration requirements for the blade server. SOL provides a means to manage servers remotely by using a command-line interface (CLI) over a Telnet or Secure Shell (SSH) connection. SOL is required to manage servers that do not have KVM support, such as the JS20 Type 8842 blade server. SOL provides console redirection for both BIOS and the blade server operating system. The SOL feature redirects server serial-connection data over a LAN without the need for special cabling. The SOL connection enables blade servers to be managed from any remote location with Internet access. The advantages of SOL include: v Remote administration without keyboard, video, or mouse (headless servers) v Reduced cabling and no need for a serial concentrator v Standard Telnet interface that eliminates the need for special client software After you install the blade server in the BladeCenter unit, the blade server is automatically configured. The Broadcom Ethernet controller device driver is installed after you install the operating system. The blade server is automatically reconfigured after you install software or hardware. IBM will periodically make firmware updates available for the blade server. Before you continue, you can make sure that the blade server has the latest version of firmware code. For additional information, see "Updating the firmware code for the blade server and the service processor" on page 40. Since the firmware code in the blade server uses auto-configuration, additional blade-server configuration programs are not required for the blade server. However, if you have attached other devices to the blade server or the BladeCenter unit, you must configure those devices as described in the applicable documentation that comes with those devices or the BladeCenter unit. You do not have to set any passwords to use the blade server. If you change the battery or replace the system-board assembly, you must reset the date and time through your operating system. For information about setting up your network configuration for remote management, see the IBM BladeCenter Planning and Installation Guide or the IBM BladeCenter T Planning and Installation Guide located at http://www.ibm.com/ support on the World Wide Web. Complete the following steps to locate the most recent version of BladeCenter documentation, including the IBM BladeCenter Planning and Installation Guide or the IBM BladeCenter T Planning and Installation Guide: 1. Go to http://www.ibm.com/support. 2. In the Learn section, click Publications. 3. On the "Publications" page, in the Brand field, select Servers. 4. In the Family field, select BladeCenter or BladeCenter T. 5. In the Type field, select the type for your BladeCenter unit. Do not change the default values in the Model and Operating system fields. © Copyright IBM Corp. 2006 35

Chapter
5.
Configuration
requirements
for
the
blade
server
This
chapter
contains
the
configuration
tasks
that
you
must
perform
so
that
you
can
run
Serial
Over
LAN
(SOL)
sessions
on
the
blade
server
and
use
the
IBM
BladeCenter
management-module
command-line
interface.
This
chapter
also
describes
other
configuration
requirements
for
the
blade
server.
SOL
provides
a
means
to
manage
servers
remotely
by
using
a
command-line
interface
(CLI)
over
a
Telnet
or
Secure
Shell
(SSH)
connection.
SOL
is
required
to
manage
servers
that
do
not
have
KVM
support,
such
as
the
JS20
Type
8842
blade
server.
SOL
provides
console
redirection
for
both
BIOS
and
the
blade
server
operating
system.
The
SOL
feature
redirects
server
serial-connection
data
over
a
LAN
without
the
need
for
special
cabling.
The
SOL
connection
enables
blade
servers
to
be
managed
from
any
remote
location
with
Internet
access.
The
advantages
of
SOL
include:
v
Remote
administration
without
keyboard,
video,
or
mouse
(headless
servers)
v
Reduced
cabling
and
no
need
for
a
serial
concentrator
v
Standard
Telnet
interface
that
eliminates
the
need
for
special
client
software
After
you
install
the
blade
server
in
the
BladeCenter
unit,
the
blade
server
is
automatically
configured.
The
Broadcom
Ethernet
controller
device
driver
is
installed
after
you
install
the
operating
system.
The
blade
server
is
automatically
reconfigured
after
you
install
software
or
hardware.
IBM
will
periodically
make
firmware
updates
available
for
the
blade
server.
Before
you
continue,
you
can
make
sure
that
the
blade
server
has
the
latest
version
of
firmware
code.
For
additional
information,
see
“Updating
the
firmware
code
for
the
blade
server
and
the
service
processor”
on
page
40.
Since
the
firmware
code
in
the
blade
server
uses
auto-configuration,
additional
blade-server
configuration
programs
are
not
required
for
the
blade
server.
However,
if
you
have
attached
other
devices
to
the
blade
server
or
the
BladeCenter
unit,
you
must
configure
those
devices
as
described
in
the
applicable
documentation
that
comes
with
those
devices
or
the
BladeCenter
unit.
You
do
not
have
to
set
any
passwords
to
use
the
blade
server.
If
you
change
the
battery
or
replace
the
system-board
assembly,
you
must
reset
the
date
and
time
through
your
operating
system.
For
information
about
setting
up
your
network
configuration
for
remote
management,
see

IBM
BladeCenter
Planning
and
Installation
Guide
or
