Powering
the
System
Off
The
HMC
user
interface
provides
a
power-off
function
to
turn
off
the
power
to
individual
processor
subsystem.
For
information
about
shutting
down
and
powering
off
a
processor
subsystem,
see
″
Basic
System
Management
Tasks

,
located
in
the
IBM
Hardware
Management
Console
for
pSeries
Installation
and
Operations
Guide
.
Note:
Service
operations
can
be
performed
to
individual
processor
subsystems
by
powering
off
individual
processor
subsystems
mounted
in
a
rack
using
the
HMC.
If
you
are
servicing
a
system
and
you
need
to
remove
power
from
the
entire
rack,
follow
all
shutdown
procedures
and
then
switch
off
the
UEPO
switch.
If
you
are
servicing
an
individual
I/O
subsystem,
refer
to
the
information
about
deactivating
a
frame’s
I/O
drawers,
see
″
Basic
System
Management

,
located
in
the
IBM
Hardware
Management
Console
for

Installation
and
Operations
Guide
to
remove
350
V
power
from
both
of
the
I/O
subsystem
DCA
UPIC
cable
connections.
Before
deactivating,
ensure
that
you
shut
down
the
operating
system
on
all
partitions
that
are
using
the
resources
of
the
I/O
subsystem
being
serviced.
After
deactivating
the
I/O
subsystem,
both
the
Power-In
LED
and
the
Power-Out
LED
on
the
front
of
the
I/O
subsystem
DCAs
should
be
off.
If
not,
call
service
support.
If
you
are
servicing
an
individual
processor
subsystem,
refer
to
the
information
about
deactivating
a
managed
system’s
service
processor,
see
″
Basic
System
Management
Tasks
″
,
located
in
the
IBM
Hardware
Management
Console
for
pSeries
Installation
and
Operations
Guide
to
remove
350
V
power
from
the
processor
subsystem
DCA
UPIC
cable
connections.
Before
deactivating,
ensure
that
you
shut
down
the
operating
system
on
all
partitions
that
are
running
on
the
processor
subsystem
being
serviced.
After
deactivating
the
processor
subsystem,
both
the
Power-In
LED
and
the
Power-Out
LED
on
the
front
of
the
processor
subsystem
DCA
should
be
off.
If
not,
do
not
continue.
Call
service
support.
Attention:
If
the
system
is
operating
in
a
full
system
partition
under
AIX,
typing
the
shutdown
command
causes
the
system
to
shut
down
and
power
off.
The
-F
option
shuts
down
the
system
without
warning
system
users.
Check
with
the
system
administrator
before
using
this
command.
If
you
cannot
use
this
method,
you
can
power
off
the
system
by
using
the
HMC.
Using
the
HMC
to
power
off
the
system
without
shutting
down
AIX
can
cause
unpredictable
results
in
the
data
files,
and
the
next
IPL
will
take
longer
to
complete.
Stopping
the
System
with
an
HMC
Attached
and
AIX
Installed
The
HMC
user
interface
provides
a
power-off
function
to
turn
off
the
power
to
the
system.
If
the
system
is
logically
partitioned,
AIX
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.
AIX
provides
hot-swap
procedures
for
adapters
and
devices
that
support
hot-swap
removal
and
installation.
You
do
not
have
to
shut
down
a
partition
that
controls
an
adapter
or
device
that
supports
hot-swap.
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
the
system.
If
the
system
is
operating
in
a
full
system
partition
under
AIX,
typing
the
shutdown
command
causes
the
system
to
shut
down
and
power
off.
The
-F
flag
shuts
down
the
system
without
warning
system
users.
Check
with
the
system
administrator
before
using
this
command.
If
you
cannot
use
this
method,
you
can
power
off
the
system
by
using
the
appropriate
command
at
the
HMC.
