Real-time diagnostics Real-time diagnostics can help you diagnose certain devices on xSeries servers while the operating system is running. Using these diagnostic actions, you can prevent and minimize server downtime. For more information and to download the real-time diagnostics, go to the following Web page: http://www-1.ibm.com/support/docview.wss?uid=psg1MIGR-50681 Running the on-board diagnostic programs To run the on-board 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. When the prompt F2 for Diagnostics appears, press F2. If you have set both a power-on password and an administrator password, you must type the administrator password to run the diagnostic programs. 4. From the top of the screen, select either Extended or Basic. 5. From the diagnostic programs screen, select the test that you want to run, and follow the instructions on the screen. To determine what action you should take as a result of a diagnostic text message or error code, see the table in "Diagnostic error codes" on page 59. A single problem might cause several text messages or error codes. When this occurs, correct the cause of the first message or error code. The other messages and error codes usually will not occur the next time you run the test. For help with the diagnostic programs, press F1. You also can press F1 from within a help screen to obtain online documentation from which you can select different categories. To exit from the help information, press Esc. If the server stops during testing and you cannot continue, restart the server and try running the diagnostic programs again. If the problem remains, replace the component that was being tested when the server stopped. The keyboard and mouse (pointing device) tests assume that a keyboard and mouse are attached to the server. If no mouse or a USB mouse is attached to the server, you cannot use the Next Cat and Prev Cat buttons to select categories. All other mouse-selectable functions are available through function keys. You can use the regular keyboard test to test a USB keyboard, and you can use the regular mouse test to test a USB mouse. You can run the USB interface test only if no USB devices are attached. The USB test will not run if a Remote Supervisor Adapter II SlimLine is installed. To view server configuration information (such as system configuration, memory contents, interrupt request (IRQ) use, direct memory access (DMA) use, device drivers, and so on), select Hardware Info from the top of the screen. 58 IBM xSeries 366 Type 8863: Problem Determination and Service Guide

Real-time
diagnostics
Real-time
diagnostics
can
help
you
diagnose
certain
devices
on
xSeries
servers
while
the
operating
system
is
running.
Using
these
diagnostic
actions,
you
can
prevent
and
minimize
server
downtime.
For
more
information
and
to
download
the
real-time
diagnostics,
go
to
the
following
Web
page:
http://www-1.ibm.com/support/docview.wss?uid=psg1MIGR-50681
Running
the
on-board
diagnostic
programs
To
run
the
on-board
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.
When
the
prompt
F2
for
Diagnostics
appears,
press
F2.
If
you
have
set
both
a
power-on
password
and
an
administrator
password,
you
must
type
the
administrator
password
to
run
the
diagnostic
programs.
4.
From
the
top
of
the
screen,
select
either
Extended
or
Basic
.
5.
From
the
diagnostic
programs
screen,
select
the
test
that
you
want
to
run,
and
follow
the
instructions
on
the
screen.
To
determine
what
action
you
should
take
as
a
result
of
a
diagnostic
text
message
or
error
code,
see
the
table
in
“Diagnostic
error
codes”
on
page
59.
A
single
problem
might
cause
several
text
messages
or
error
codes.
When
this
occurs,
correct
the
cause
of
the
first
message
or
error
code.
The
other
messages
and
error
codes
usually
will
not
occur
the
next
time
you
run
the
test.
For
help
with
the
diagnostic
programs,
press
F1.
You
also
can
press
F1
from
within
a
help
screen
to
obtain
online
documentation
from
which
you
can
select
different
categories.
To
exit
from
the
help
information,
press
Esc.
If
the
server
stops
during
testing
and
you
cannot
continue,
restart
the
server
and
try
running
the
diagnostic
programs
again.
If
the
problem
remains,
replace
the
component
that
was
being
tested
when
the
server
stopped.
The
keyboard
and
mouse
(pointing
device)
tests
assume
that
a
keyboard
and
mouse
are
attached
to
the
server.
If
no
mouse
or
a
USB
mouse
is
attached
to
the
server,
you
cannot
use
the
Next
Cat
and
Prev
Cat
buttons
to
select
categories.
All
other
mouse-selectable
functions
are
available
through
function
keys.
You
can
use
the
regular
keyboard
test
to
test
a
USB
keyboard,
and
you
can
use
the
regular
mouse
test
to
test
a
USB
mouse.
You
can
run
the
USB
interface
test
only
if
no
USB
devices
are
attached.
The
USB
test
will
not
run
if
a
Remote
Supervisor
Adapter
II
SlimLine
is
installed.
To
view
server
configuration

as
system
configuration,
memory
contents,
interrupt

(IRQ)
use,

device
drivers,
and
so
on),
