Chapter 7. Solving problems This chapter provides basic troubleshooting information to help you solve some common problems that might occur while setting up your blade server. A problem with the BladeCenter QS21 can relate either to the BladeCenter QS21 or the BladeCenter unit. A problem with the blade server exists if the BladeCenter unit contains more than one blade server and only one of the blade servers has the symptom. If all of the blade servers have the same symptom, then the problem relates to the BladeCenter unit. For more information, see the documentation that comes with your BladeCenter unit. Note: The BladeCenter QS21 is supported in the BladeCenter H Type 8852 unit and the BladeCenter HT Type 8740 and 8750 (enterprise environment only) unit. However you can put other blade servers compatible with the BladeCenter units in the same unit as a BladeCenter QS21. Prerequisites Before you start problem determination or servicing, check that: v The BladeCenter QS21 is inserted correctly into the BladeCenter unit v All components are connected correctly v The BladeCenter QS21 has the latest firmware updates. These include: - BMC - System - Gigabit Ethernet controller - SAS expansion card (if installed) - InfiniBand high-speed expansion card (if installed) Basic checks If you install the blade server in the BladeCenter unit and the blade server does not start, always perform the following basic checks before continuing with more advanced troubleshooting: v Make sure that the BladeCenter unit is correctly connected to a power source. v Reseat the blade server in the BladeCenter unit (see Chapter 3, "Installing the blade server," on page 15). v If the power on LED is flashing slowly, the blade server may be turned off. To turn on the blade server, see "Turning on the blade server" on page 9 for further information. v If you have just added a new optional device or component, make sure that it is correctly installed and compatible with the blade server and its components. If the device or component is not compatible, remove it from the blade server, reinstall the blade server in the BladeCenter unit, and then restart the blade server. v Use Advanced Management Module to check that the blade server appears in the list of blade servers available. © Copyright IBM Corp. 2006, 2008 59

Chapter
7.
Solving
problems
This
chapter
provides
basic
troubleshooting
information
to
help
you
solve
some
common
problems
that
might
occur
while
setting
up
your
blade
server.
A
problem
with
the
BladeCenter
QS21
can
relate
either
to
the
BladeCenter
QS21
or
the
BladeCenter
unit.
A
problem
with
the
blade
server
exists
if
the
BladeCenter
unit
contains
more
than
one
blade
server
and
only
one
of
the
blade
servers
has
the
symptom.
If
all
of
the
blade
servers
have
the
same
symptom,
then
the
problem
relates
to
the
BladeCenter
unit.
For
more
information,
see
the
documentation
that
comes
with
your
BladeCenter
unit.
Note:
The
BladeCenter
QS21
is
supported
in
the
BladeCenter
H
Type
8852
unit
and
the
BladeCenter
HT
Type
8740
and
8750
(enterprise
environment
only)
unit.
However
you
can
put
other
blade
servers
compatible
with
the
BladeCenter
units
in
the
same
unit
as
a
BladeCenter
QS21.
Prerequisites
Before
you
start
problem
determination
or
servicing,
check
that:
v
The
BladeCenter
QS21
is
inserted
correctly
into
the
BladeCenter
unit
v
All
components
are
connected
correctly
v
The
BladeCenter
QS21
has
the
latest
firmware
updates.
These
include:
–
BMC
–
System
–
Gigabit
Ethernet
controller
–
SAS
expansion
card
(if
installed)
–
InfiniBand
high-speed
expansion
card
(if
installed)
Basic
checks
If
you
install
the
blade
server
in
the
BladeCenter
unit
and
the
blade
server
does
not
start,
always
perform
the
following
basic
checks
before
continuing
with
more
advanced
troubleshooting:
v
Make
sure
that
the
BladeCenter
unit
is
correctly
connected
to
a
power
source.
v
Reseat
the
blade
server
in
the
BladeCenter
unit
(see
Chapter
3,
“Installing
the
blade
server,”
on
page
15).
v
If
the
power
on
LED
is
flashing
slowly,
the
blade
server
may
be
turned
off.
To
turn
on
the
blade
server,
see
“Turning
on
the
blade
server”
on
page
9
for
further
information.
v
If
you
have
just
added
a
new
optional
device
or
component,
make
sure
that
it
is
correctly
installed
and
compatible
with
the
blade
server
and
its
components.
If
the
device
or
component
is
not
compatible,
remove
it
from
the
blade
server,
reinstall
the
blade
server
in
the
BladeCenter
unit,
and
then
restart
the
blade
server.
v
Use
Advanced
Management
Module
to
check
that
the
blade
server
appears
in
the
list
of
blade
servers
available.
