Operating
System
Surveillance
Note:
Operating
system
surveillance
is
disabled
in
partitioned
systems.
Operating
system
surveillance
provides
the
service
processor
with
a
means
to
detect
hang
conditions,
as
well
as
hardware
or
software
failures,
while
the
operating
system
is
running.
It
also
provides
the
operating
system
with
a
means
to
detect
a
service
processor
failure
caused
by
the
lack
of
a
return
heartbeat.
Operating
system
surveillance
is
not
enabled
by
default,
allowing
you
to
run
operating
systems
that
do
not
support
this
service
processor
option.
You
can
also
use
service
processor
menus
and
AIX
service
aids
to
enable
or
disable
operating
system
surveillance.
For
operating
system
surveillance
to
work
correctly,
you
must
set
these
parameters:
v
Surveillance
enable/disable
v
Surveillance
interval
The
maximum
time
the
service
processor
should
wait
for
a
heartbeat
from
the
operating
system
before
timeout.
v
Surveillance
delay
The
length
of
time
to
wait
from
the
time
the
operating
system
is
started
to
when
the
first
heartbeat
is
expected.
Surveillance
does
not
take
effect
until
the
next
time
the
operating
system
is
started
after
the
parameters
have
been
set.
If
desired,
you
can
initiate
surveillance
mode
immediately
from
service
aids.
In
addition
to
the
three
options
above,
a
fourth
option
allows
you
to
select
immediate
surveillance,
and
rebooting
of
the
system
is
not
necessarily
required.
If
operating
system
surveillance
is
enabled
(and
system
firmware
has
passed
control
to
the
operating
system),
and
the
service
processor
does
not
detect
any
heartbeats
from
the
operating
system,
the
service
processor
assumes
the
system
is
hung
and
takes
action
according
to
the
reboot/restart
policy
settings.
See
If
surveillance
is
selected
from
the
service
processor
menus
that
are
only
available
at
system
boot,
then
surveillance
is
enabled
by
default
as
soon
as
the
system
boots.
From
service
aids,
the
selection
is
optional.
