Checkpoints
display
on
the
media
subsystem
operator
panel
and
the
virtual
terminal
while
the
system
is
powering
on
and
going
through
the
initial
program
load
(IPL).
This
chapter
explains
the
IPL
flow
of
the
system
and
provides
a
table
that
lists
checkpoints
that
you
might
see
in
the
media
subsystem
operator
panel
and
in
a
virtual
terminal
window
on
the
HMC.
IPL
Flow
The
IPL
process
starts
when
ac
power
is
connected
to
the
system.
The
IPL
process
has
the
following
phases:
v
Phase
1:
Service
Processor
Initialization
Phase
1
starts
when
ac
power
is
connected
to
the
system
and
ends
when
OK
is
displayed
in
the
media
subsystem
operator
panel.
8xxx
checkpoints
are
displayed
during
this
phase.
Several
9xxx
codes
may
also
be
displayed.
Service
processor
menus
are
available
at
the
end
of
this
phase
by
striking
any
key
on
the
console
keyboard.
v
Phase
2:
Hardware
Initialization
by
the
Service
Processor
Phase
2
starts
when
system
power-on
is
initiated
by
pressing
the
power
on
button
on
the
media
subsystem
operator
panel.
9xxx
checkpoints
are
displayed
during
this
time.
91FF,
the
last
checkpoint
in
this
phase,
indicates
the
transition
to
phase
3
is
taking
place.
v
Phase
3:
System
Firmware
initialization
On
a
full
system
partition,
at
phase
3,
a
system
processor
takes
over
control
and
continues
initializing
partition
resources.
During
this
phase,
checkpoints
in
the
form
Exxx
are
displayed.
E105,
the
last
checkpoint
in
this
phase,
indicates
that
control
is
being
passed
to
the
operating
system
boot
program.
On
a
partitioned
system,
there
is
a
global
systemwide
initialization
phase
3,
during
which
a
system
processor
continues
the
initialization
process.
Checkpoints
in
this
phase
are
of
the
form
Exxx.
This
global
phase
3
ends
with
a
"LPAR..."
on
the
operator
panel.
As
a
logical
partition
begins
a
partition-initialization
phase
3,
one
of
the
system
processors
assigned
to
that
partition
continues
initialization
of
resource
assigned
to
that
partition.
Checkpoints
in
this
phase
are
also
of
the
form
Exxx.
This
partition
phase
3
ends
with
an
E105
displayed
on
the
partition’s
virtual
operator
panel
on
the
HMC,
indicating
control
has
been
passed
to
that
logical
partition’s
operating
system
boot
program.
For
both
the
global
and
partition
phase
3,
location
codes
may
also
be
displayed
on
the
physical
operator
panel
and
the
partition’s
virtual
terminal,
respectively.
v
Phase
4:
Operating
System
Boot
When
the
operating
system
starts
to
boot,
checkpoints
in
the
form
0xxx
and
2xxx
are
displayed.
This
phase
ends
when
the
operating
system
login
prompt
displays
on
the
operating
system
console.
