Maintenance
Analysis
Procedures
(MAPs)
This
chapter
contains
maintenance
analysis
procedures
(MAPs)
for
the
system.
Entry
MAP
Use
the
following
table
to
determine
your
starting
point.
When
possible,
run
online
diagnostics
in
service
mode.
Online
diagnostics
perform
additional
functions,
compared
to
standalone
diagnostics.
This
ensures
that
the
error
state
of
the
system
is
captured
in
NVRAM
for
your
use
in
fixing
the
problem.
The
AIX
error
log
and
SMIT
are
only
available
when
diagnostics
are
run
from
the
hard
drive.
Notes:
1.
Licensed
programs
frequently
rely
on
system
information
stored
on
the
VPD
module
on
the
operator
panel
assembly.
If
the
MAPs
indicate
that
the
operator
panel
assembly
should
be
replaced,
swap
the
VPD
module
from
the
old
operator
panel
to
the
new
one.
If
recovery
is
not
possible,
notify
the
system
owner
that
new
keys
for
licensed
programs
may
be
required.
2.
If
a
network
adapter
is
replaced,
the
network
administrator
must
be
notified
so
that
the
client
IP
addresses
used
by
the
server
can
be
changed.
In
addition,
the
operating
system
configuration
of
the
network
controller
may
need
to
be
changed
in
order
to
enable
system
startup.
Also
check
to
ensure
that
any
client
or
server
that
addresses
this
system
is
updated.
