Diagnostic programs and messages The Dynamic System Analysis (DSA) Preboot diagnostic programs are the primary method of testing the major components of the server. DSA is a system information collection and analysis tool that you can use to provide information IBM service and support to aid in the diagnosis of the system problems. The DSA diagnostic programs come on the IBM Dynamic System Analysis Preboot Diagnostic CD. You can download the CD from http://www.ibm.com/support/us/en if one did not come with your server. As you run the diagnostic programs, text messages are displayed on the screen and are saved in the test log. A diagnostic text message indicates that a problem has been detected and indicates the action you should take as a result of the text message. The DSA diagnostic programs collect the following information about the following aspects of the system: v System configuration v Network interfaces and settings v Hardware inventory USB information v IBM LightPath diagnostics status v Service processor status and configuration v Vital product data and system firmware information v Drive Health Information v LSI RAID & Controller configuration The DSA diagnostic programs can also provide diagnostics for the following system components: v Baseboard Management Controller v Memory stress v CPU stress Additionally, DSA creates a merged log that includes events from all collected logs. All collected information can be output as a compressed XML file that can be sent to IBM Service. Additionally, you can view the information locally through a generated text report file. Optionally, the generated HTML pages may be copied to removable media and viewed from a web browser. Running diagnostics and preboot DSA To run the diagnostic programs, complete the following steps: 1. If the server is running, turn off the server and all attached devices. 2. Turn on all attached devices then turn on the server. 3. Ensure that external DSA bootable media is available as a boot device. For boot device selection, system firmware will work through the boot path as specified in the onboard planar VPD and try to establish communication with the specified interfaces in sequential order. These boot devices include the USB attached DVD (BladeCenter, media tray), the SAS storage if attached , as well as Network attached storage. Note: To ensure the blade server boots from the correct device, use the Advanced Management Module to change the boot order so the blade server boots first from the preboot DSA device. 4.

Diagnostic
programs
and
messages
The
Dynamic
System
Analysis
(DSA)
Preboot
diagnostic
programs
are
the
primary
method
of
testing
the
major
components
of
the
server.
DSA
is
a
system
information
collection
and
analysis
tool
that
you
can
use
to
provide
information
IBM
service
and
support
to
aid
in
the
diagnosis
of
the
system
problems.
The
DSA
diagnostic
programs
come
on
the
IBM
Dynamic
System
Analysis
Preboot
Diagnostic
CD.
You
can
download
the
CD
from
if
one
did
not
come
with
your
server.
As
you
run
the
diagnostic
programs,
text
messages
are
displayed
on
the
screen
and
are
saved
in
the
test
log.
A
diagnostic
text
message
indicates
that
a
problem
has
been
detected
and
indicates
the
action
you
should
take
as
a
result
of
the
text
message.
The
DSA
diagnostic
programs
collect
the
following
information
about
the
following
aspects
of
the
system:
v
System
configuration
v
Network
interfaces
and
settings
v
Hardware
inventory
USB
information
v
IBM
LightPath
diagnostics
status
v
Service
processor
status
and
configuration
v
Vital
product
data
and
system
firmware
information
v
Drive
Health
Information
v
LSI
RAID
&
Controller
configuration
The
DSA
diagnostic
programs
can
also
provide
diagnostics
for
the
following
system
components:
v
Baseboard
Management
Controller
v
Memory
stress
v
CPU
stress
Additionally,
DSA
creates
a
merged
log
that
includes
events
from
all
collected
logs.
All
collected
information
can
be
output
as
a
compressed
XML
file
that
can
be
sent
to
IBM
Service.
Additionally,
you
can
view
the
information
locally
through
a
generated
text
report
file.
Optionally,
the
generated
HTML
pages
may
be
copied
to
removable
media
and
viewed
from
a
web
browser.
Running
diagnostics
and
preboot
DSA
To
run
the
diagnostic
programs,
complete
the
following
steps:
1.
If
the
server
is
running,
turn
off
the
server
and
all
attached
devices.
2.
Turn
on
all
attached
devices
then
turn
on
the
server.
3.
Ensure
that
external
DSA
bootable
media
is
available
as
a
boot
device.
For
boot
device
selection,
system
firmware
will
work
through
the
boot
path
as
specified
in
the
onboard
planar
VPD
and
try
to
establish
communication
with
the
specified
interfaces
in
sequential
order.
These
boot
devices
include
the
USB
attached
DVD
(BladeCenter,
media
tray),
the
SAS
storage
if
attached
,
as
well
as
Network
attached
storage.
Note:
To
ensure
the
blade
server
boots
from
the
correct
device,
use
the
Advanced
Management
Module
to
change
the
boot
order
so
the
blade
server
boots
first
from
the
preboot
DSA
device.
