Reco

a
System
P

In HP-UX
terms,
a
system
panic
simply
means
that
the
op
erating
system
encoun
tered
a
condition
that
it
did
not
kno
w
how
to resp
ond to,
so it
halted
y
our con
troller.
System panics
are rare
and not
alwa
ys
the
result
of
a
catastrophe.
They
sometimes
o
ccur
at
b
o
ot
if
y
our
system
w
as
previously
not
sh
ut do
wn prop
erly.
Sometimes
they
o
ccur
as
the
result
of
a
hardware
failure. In
a clustered
environmen
t, a
diskless clien
t
no
de
will
panic
if
to
o
m
uc
h
time
has
elapsed
since
its
last
comm
unication
with
its
serv
er.
This
could
b
e
the
result
of
nothing
more
than
a
LAN
cable
that has
been
disconnected for
to o
long.
Reco
vering
from
a
system
panic
can
b
e
as
simple
as
reb
o
oting
y
our
system.
