MAP
1542:
I/O
Problem
Isolation
This
MAP
is
used
to
locate
defective
FRUs
not
found
by
normal
diagnostics.
For
this
procedure,
diagnostics
are
run
on
a
minimally
configured
system.
If
a
failure
is
detected
on
the
minimally
configured
system,
the
remaining
FRUs
are
exchanged
one
at
a
time
until
the
failing
FRU
is
identified.
If
a
failure
is
not
detected,
FRUs
are
added
back
until
the
failure
occurs.
The
failure
is
then
isolated
to
the
failing
FRU.
This
I/O
problem-determination
MAP
isolates
I/O
card
and
I/O
subsystem
failures.
When
I/O
problem
isolation
is
complete,
all
cables
and
cards
exhibiting
a
failure
will
have
been
replaced
or
reseated.
Notes:
1.
This
MAP
assumes
that
a
CD-ROM
drive
is
installed
in
the
media
subsystem
and
connected
to
a
SCSI
adapter
in
the
first
I/O
subsystem,
and
that
a
Diagnostics
CD-ROM
is
available.
2.
If
a
general-access
password
or
privileged-access
password
is
installed,
you
are
prompted
to
enter
the
password
before
the
diagnostic
CD-ROM
can
load.
3.
The
term
POST
indicators
refers
to
the
device
mnemonics
(words
Memory
,
Keyboard
,
Network
,
SCSI
,
and
Speaker
)
that
appear
on
the
system
console
during
the
power-on
self-test
(POST).
4.
The
service
processor
may
have
recorded
one
or
more
symptoms
in
its
error
log.
It
is
a
good
idea
to
examine
that
error
log
before
proceeding
(see
5.
The
service
processor
may
have
been
set
by
the
user
to
monitor
system
operations
and
to
attempt
recoveries.
You
can
disable
these
actions
while
you
diagnose
and
service
the
system.
If
you
disable
them,
make
notes
of
their
current
settings
so
that
you
can
restore
them
easily.
The
following
table
lists
the
settings:
Surveillance
From
the
service
processor
Setup
Menu,
go
to
the
Surveillance
Setup
Menu
and
disable
surveillance.
(Operating
System
Surveillance
is
disabled
in
partition
mode.)
Unattended
Start
From
the
service
processor
System
Power
Control
Menu,
disable
unattended
start
mode.
Reboot
Policy
From
the
System
Power
Control
Menu,
go
to
the
Reboot/Restart
Policy
Setup
Menu
and
set:
1.
Number
of
reboot
attempts
to
0
(zero)
2.
Use
OS-Defined
restart
policy
to
No
3.
Enable
supplemental
restart
policy
to
No
.
Call
Out
From
the
Call-In/Call-Out
Setup
Menu,
go
to
the
Serial
Port
Selection
Menu
and
disable
call-out
on
both
serial
ports.
The
steps
in
this
MAP
will
attempt
to
slow
boot
the
system
into
service
mode
diagnostics.
The
following
procedure
describes
booting
a
nonpartitioned
system
with
an
attached
3151
console.
The
procedure
for
booting
a
partitioned
system
with
an
attached
HMC
is
slightly
different
and
is
described
in
“Performing
Slow
Boot”
describes
the
procedure
for
booting
online
diagnostics
(6
key
between
the
Keyboard
and
Speaker
indicators)
and
the
following
procedure
requires
booting
standalone
diagnostics
(5
key
between
the
Keyboard
and
Speaker
indicators).
Therefore,
on
a
partitioned
system,
make
sure
the
partition
you
selected
to
boot
in
the
following
procedure
has
the
CD-ROM
allocated
to
it,
as
described
in
