Chapter
2.
Diagnostics
Overview
Eserver
pSeries
690
servers
use
an
integrated
set
of
software
diagnostic
procedures
to
facilitate
system
maintenance.
This
book
and
the
RS/6000
and
Eserver
pSeries
Diagnostic
Information
for
Multiple
Bus
Systems
are
the
basis
of
the
diagnostic
procedures
for
Eserver
pSeries
690
systems.
In
particular,
chapters
3,
4,
5,
and
10
in
this
book
are
important
for
the
trained
service
representative
to
understand
and
use
when
isolating
a
failure
on
the
system.
The
manufacturer
recommends
that
systems
configured
with
4
GB
of
memory
or
greater
have
access
to
a
4-mm
or
8-mm
tape
drive
for
submission
of
system
dump
information
if
it
is
required.
This
function
can
be
accomplished
through
locally
attached
or
network-attached
devices,
as
appropriate.
Maintenance
Analysis
Procedures
(MAPs)
Maintenance
Analysis
Procedures
(MAPs)
guide
trained
service
representatives
through
the
complex
multirack
Eserver
pSeries
690
system.
These
MAPs
are
the
entry
point
for
all
isolation
and
error-recovery
procedures.
Eserver
pSeries
690
systems
use
a
set
of
integrated
procedures,
to
which
the
MAPS
are
the
primary
entry
point.
The
MAPS
are
as
follows:
v
Entry
MAP
v
Quick
Entry
MAP
v
Service
Focal
Point
Procedures
v
Power
MAP
v
Problem
Isolation
MAP
The
Entry
Map
is
the
starting
point
for
problem
determination.
The
purpose
of
this
MAP
is
to
quickly
point
to
the
appropriate
MAP
or
service
reference
information
either
in
this
book,
or
in
the
common
book
set,
which
includes
the
RS/6000
and
Eserver
pSeries
Diagnostic
Information
for
Multiple
Bus
Systems
and
PCI
Adapter
Placement
Reference
.
The
Quick
Entry
MAP
is
a
subset
of
the
Entry
MAP
and
helps
to
save
time
for
some
types
of
problems.
The
Power
MAP
deals
with
isolation
of
components
and
cables
to
diagnose
a
power
problem.
The
nature
of
power
problems
can
be
related
to
powering
the
system
on
and
off,
or
power
failures
that
can
occur
after
power
is
turned
on.
The
Problem
Isolation
MAP
is
used
to
locate
defective
components
not
found
by
normal
diagnostics
or
error-isolation
methods.
This
MAP
provides
a
systematic
method
of
isolation
to
the
failing
item
or
items.
Checkpoints
Eserver
pSeries
690
systems
use
various
types
of
checkpoints,
error
codes,
and
SRNs
that
are
referred
to
throughout
this
book
(primarily
in
Chapters
3,
4
and
5).
On
an
HMC-managed
system,
the
checkpoints
and
error
codes
displayed
on
the
physical
operator
panel
are
also
displayed
on
the
HMC
virtual
terminal
associated
with
the
managed
system
object.
On
a
system
operating
as
a
full
system
partition,
checkpoints
and
error
codes
will
appear
on
the
physical
operator
panel
from
the
beginning
of
the
power-on
process
through
the
completion
of
booting
AIX.
On
a
partitioned
system,
checkpoints
and
error
codes
for
a
partition
are
displayed
on
the
HMC
virtual
operator
panel
associated
with
that
logical
partition.
Checkpoints
and
error
codes
generated
by
logical
partitions
are
not
displayed
on
the
managed
system’s
physical
operator
panel.
