Boot
Problems
Attention:
If
the
system
is
running
partitions
from
partition
standby
(LPAR),
the
following
procedure
addresses
the
problem
in
which
one
partition
will
not
boot
while
other
partitions
boot
successfully
and
run
the
operating
system
successfully.
This
procedure
also
addresses
the
problem
in
which
a
system
does
not
boot
to
a
full
system
partition.
All
of
the
system’s
resources
are
available
to
the
diagnostics;
the
same
general
procedure
applies,
with
the
exception
of
moving
resources
between
partitions.
Attention:
It
is
the
customer’s
responsibility
to
move
devices
between
partitions.
If
a
device
must
be
moved
to
another
partition
to
run
standalone
diagnostics,
contact
the
customer
or
system
administrator.
(If
the
CD-ROM
must
be
moved
to
another
partition,
all
SCSI
devices
connected
to
that
SCSI
adapter
must
be
moved
because
moves
are
done
at
the
slot
level,
not
at
the
device
level.)
Both
partitions
must
be
rebooted
if
a
device
is
moved
between
partitions.
Depending
on
the
boot
device,
a
checkpoint
may
be
displayed
on
the
operator
panel
for
an
extended
period
of
time
while
the
boot
image
is
retrieved
from
the
device.
This
is
particularly
true
for
tape
and
network
boot
attempts.
If
the
checkpoint/code
is
displayed
for
an
extended
time,
there
may
be
a
problem
loading
the
boot
image
from
the
device.
If
booting
from
CD-ROM
or
tape,
watch
for
activity
on
the
drive’s
LED
indicator.
A
blinking
LED
indicates
that
the
loading
of
either
the
boot
image,
or
additional
information
required
by
the
operating
system
being
booted,
is
still
being
loaded.
For
network
boot
attempts,
refer
to
checkpoint
E174.
If
the
checkpoint
is
displayed
for
an
extended
time,
there
may
be
a
problem
with
the
integrity
of
the
boot
image.
This
procedure
assumes
that
a
CD-ROM
drive
is
connected
to
the
system,
or
that
the
diagnostics
can
be
run
from
a
NIM
(Network
Installation
Management)
server.

Look
at
the
service
action
event-error
log
in
the
Service
Focal
Point
on
the
HMC
(see
for
instructions
on
accessing
the
service
action
event
log).
If
there
are
open
entries
that
affect
devices
in
the
boot
path
of
the
partition,
perform
the
actions
to
correct
those
errors.
If
there
are
open
entries
that
indicate
problems
with
I/O
cabling,
perform
the
actions
to
correct
those
problems.
Try
to
reboot
the
partition.
If
the
partition
hangs
with
a
4-character
checkpoint
in
the
display,
the
partition
must
be
deactivated,
then
reactivated
before
attempting
to
reboot.
If
a
20EE
xxxx
error
code
is
reported,
the
partition
is
already
deactivated
and
in
the
error
state.
Reboot
by
activating
the
partition.
If
the
system
is
running
in
full
system
partition,
the
power
must
be
cycled
before
the
system
can
be
rebooted.
If
the
reboot
is
still
not
successful,
continue
