Problem determination tips Because of the variety of hardware and software combinations that can be encountered, use the following information to assist you in problem determination. If possible, have this information available when requesting assistance from Service Support and Engineering functions. v Machine type and model v Microprocessor or hard disk upgrades v Failure symptom - Do diagnostics fail? - What message appears in the diagnostics log? - What, when, where, single, or multiple systems? - Is the failure repeatable? - Has this configuration ever worked? - If it has been working, what changes were made prior to it failing? - Is this the original reported failure? v Diagnostics version - Type and version level v Hardware configuration - Print (print screen) configuration currently in use - BIOS level v Operating system software - Type and version level Note: To eliminate confusion, identical systems are considered identical only if they: v Are the exact machine type and models v Have the same BIOS level v Have the same adapters/attachments in the same locations v Have the same address jumpers/terminators/cabling v Have the same software versions and levels v Have the same diagnostics code (version) v Have the same configuration options set in the system v Have the same setup for the operation system control files Comparing the configuration and software set-up between "working" and "non-working" systems will often lead to problem resolution. 128 xSeries 226 Type 8488 and 8648: Hardware Maintenance Manual and Troubleshooting Guide

Problem

tips
Because
of
the
variety
of
hardware
and
software
combinations
that
can
be
encountered,
use
the
following
information
to
assist
you
in
problem
determination.
If
possible,
have
this
information
available
when
requesting
assistance
from
Service
Support
and
Engineering
functions.
v
Machine
type
and
model
v
Microprocessor
or
hard
disk
upgrades
v
Failure
symptom
–
Do
diagnostics
fail?
–
What
message
appears
in
the
diagnostics
log?
–
What,
when,
where,
single,
or
multiple
systems?
–
Is
the
failure
repeatable?
–
Has
this
configuration
ever
worked?
–
If
it
has
been
working,
what
changes
were
made
prior
to
it
failing?
–
Is
this
the
original
reported
failure?
v
Diagnostics
version
–
Type
and
version
level
v
Hardware
configuration
–
Print
(print

configuration
currently
in
use
–
BIOS
level
v
Operating
system
software
–
Type
and
version
level
Note:
To
eliminate
confusion,
identical
systems
are
considered
identical
only
if
they:
v
Are
the
exact
machine
type
and
models
v
Have
the
same
BIOS
level
v
Have
the
same
adapters/attachments
in
the
same
locations
v
Have
the
same
address
jumpers/terminators/cabling
v
Have
the
same
software
versions
and
levels
v
Have
the
same
diagnostics
code
(version)
v
Have
the
same
configuration
options
set
in
the
system
v
Have
the
same
setup
for
the
operation
system
control
files
Comparing
the
configuration
and
software
set-up
between
“working”
and
“non-working”
systems
will
often
lead
to
problem
resolution.
