Attention:
Using
the
HMC
to
power
off
the
system
can
cause
unpredictable
results
in
the
data
files.
The
next
IPL
will
also
take
longer
to
complete
if
all
applications
in
all
partitions
are
not
stopped
first.
Stopping
the
System
with
an
HMC
Attached
and
Linux
Installed
The
HMC
user
interface
provides
a
power-off
function
to
turn
off
the
power
to
the
system.
If
the
system
is
logically
partitioned,
Linux
in
each
partition
may
be
stopped
individually
to
make
repairs.
If
the
system
power
must
be
turned
off,
all
of
the
logical
partitions
must
be
stopped.
Linux
does
not
provide
hot-swap
procedures
for
adapter
and
device
removal
and
installation.
You
must
shut
down
all
partitions,
and
the
system
power
must
be
turned
off
to
service
an
adapter
or
device.
Individual
power
components
and
fans
can
be
serviced
with
power
on
for
power
systems
equipped
with
redundant
power
and
cooling.
Check
the
removal
and
installation
procedures
before
servicing
this
system.
If
the
system
is
operating
in
a
full-system
partition
under
Linux,
typing
the
shutdown
now
-h
command
causes
the
system
to
shut
down
and
power
off.
Check
with
the
system
administrator
before
using
this
command.
If
you
cannot
use
this
method,
you
can
power
off
the
system
using
the
HMC.
Attention:
Using
the
HMC
to
power
off
the
system
can
cause
unpredictable
results
in
the
data
files.
The
next
IPL
will
also
take
longer
to
complete
if
all
applications
in
all
partitions
are
not
stopped
first.
Powering
On
the
System
Using
the
Service
Processor
The

can
be
powered
on
using
the
System
Power
Control
menu,
which
is
a
service
processor
menu
that
is
available
to
the
privileged
user.

This
procedure
requires:
v
The
use
of
a
lift
tool
(part
number
09P2481)
and
lift-plate
assembly
tool
(part
number
11P4369).
v
The
lift
tool
wheels
must
be
chocked
to
prevent
it
from
moving
during
the
operation.
The
rack
must
not
be
on
its
casters.
The
leveling
pads
must
be
engaged
to
prevent
the
rack
from
moving
during
the
operation.
To
replace
the
processor
subsystem
into
the
rack,
do
the
following:
1.
Position
the
lift
tool
near
the
processor
subsystem
so
it
can
be
lifted
onto
the
lift
plate.
2.
Install
the
wheel
chocks,
and
engage
the
brake
on
the
lift
tool.
3.
Adjust
the
sliding
part
of
the
lift
plate
so
that
it
can
be
moved
toward
the
rack
when
the
lift
tool
is
positioned
in
front
of
the
rack.
Note:
The
sliding
part
of
the
lift
plate
can
be
positioned
to
move
in
two
directions.
4.
Pull
the
release
buttons
on
the
lift
plate
and
slide
the
lift-plate
tray
to
the
maximum
distance.
5.
Position
the
processor
subsystem
onto
the
lift
plate
with
the
back
edge
of
the
processor
subsystem
at
the
edge
of
the
lift
plate.
6.
Tie
the
processor
subsystem
to
the
lift
plate
with
tie-down
straps.
7.
At
the
front
of
the
rack,
ensure
that
the
cover
on
the
frame
cage
is
lifted
and
locked
in
the
open
position.
8.
Move
the
lift
tool
into
position
in
front
of
the
