Recov

System
P
anic
In
HP-UX
terms,
a
system
panic
simply
means
that
the
op erating
system
encoun
tered
a
condition
that
it
did
not
kno
w
ho
w
to
resp ond
to,
so
it
halted
y
our
w
orkstation.
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

as
previously
not
sh
ut
do
wn
prop erly
.
Sometimes
they
o ccur
as
the
result
of
a
hardw
are
failure.
In
a
clustered
en
vironmen
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
b een
disconnected
for
to
o
long.
Reco
