v Diagnostic utilities for the Linux and AIX operating systems Diagnostic utilities for the Linux operating system are available from IBM. For more information, go to http://www.ibm.com/servers/eservers/support/ bladecenter/; in the Hardware field select BladeCenter JS20, in the Software field select Linux on POWER environment, then click Go. A diagnostic CD for the AIX operating system is available from IBM. Go to http://techsupport.services.ibm.com/server/mdownload/diags/download to download the CD image. See the BladeCenter JS20 Type 8842 Hardware Maintenance Manual and Troubleshooting Guide for instructions on using the utilities. Other supported operating systems might have diagnostic tools available through the operating system. Consult your operating system documentation for more information. Notes: v For additional information about firmware error codes, location codes, error logs, event logs, and firmware checkpoints, see the BladeCenter JS20 Type 8842 Hardware Maintenance Manual and Troubleshooting Guide. v If you are unable to find the system error logs in the blade-server firmware code, view the system event logs in the BladeCenter management module. v Before you have the blade server serviced, make sure that you provide a Serial Over LAN (SOL) connection to the blade server. To do this, you must configure the SOL feature on the blade server and start an SOL session as described in the IBM BladeCenter and BladeCenter T Serial Over LAN Setup Guide. System checkout If your system fails to start after installation or an error occurs while running, perform the following steps: 1. Visually check the blade server system board for any lit external LEDs. a. Turn off the server. b. Remove the blade server from the BladeCenter unit. c. Open the blade server and press and hold the light path diagnostics button. See "Light path diagnostics table" on page 81 for the location of the light path diagnostics button. d. Perform the steps in "Identifying problems using the light path diagnostics" on page 80 to identify lit error LEDs on the blade server. 1) If any LEDs light, see "Light path diagnostics table" on page 81. 2) If there is no error LED lit, proceed to the next step. 2. Reinstall the blade server in the same bay of the BladeCenter unit. 3. To test the blade server, turn on the blade server and start an SOL session (see the IBM BladeCenter and BladeCenter T Serial Over LAN Setup Guide). 4. Observe the progress codes in the SOL window and record any POST error messages or system checkpoint codes that occur. If an error occurs, see "Firmware error codes" on page 65 for more information. 5. Review the BladeCenter management-module event log and Linux Syslog to see if an error was recorded. If there is a hardware error, contact a service support representative and provide the details of the problem. If there is no hardware error, contact a service support representative for more information to resolve your problem. 48 BladeCenter JS20 Type 8842: Installation and User's Guide

System
checkout
If
your
system
fails
to
start
after
installation
or
an
error
occurs
while
running,
perform
the
following
steps:
1.
Visually
check
the
blade
server
system
board
for
any
lit
external
LEDs.
a.
Turn
off
the
server.
b.
Remove
the
blade
server
from
the
BladeCenter
unit.
c.
Open
the
blade
server
and
press
and
hold
the
light
path
diagnostics
button.
See
“Light
path
diagnostics
table”
on
page
81
for
the
location
of
the
light
path
diagnostics
button.
d.
Perform
the
steps
in
“Identifying
problems
using
the
light
path
diagnostics”
on
page
80
to
identify
lit
error
LEDs
on
the
blade
server.
1)
If
any
LEDs
light,
see
“Light
path
diagnostics
table”
on
page
81.
2)
If
there
is
no
error
LED
lit,
proceed
to
the
next
step.
2.
Reinstall
the
blade
server
in
the
same
bay
of
the
BladeCenter
unit.
3.
To
test
the
blade
server,
turn
on
the
blade
server
and
start
an
SOL
session
(see
the
IBM
BladeCenter
and
BladeCenter
T
Serial
Over
LAN
Setup
Guide
).
4.
Observe
the
progress
codes
in
the
SOL
window
and
record
any
POST
error
messages
or
system
checkpoint
codes
that
occur.
If
an
error
occurs,
see

Syslog
to
see
if
an
error
was
recorded.
If
there
is
a
hardware
error,
contact
a
