Error
codes
Error
codes
are
displayed
on
the
front
panel
display.
For
descriptions
of
the
error
codes
that
are
displayed
on
the
front
panel
display,
see
the
various
error
code
topics
for
a
full
description
of
the
failure
and
the
actions
that
you
must
perform
to
correct
the
failure.
Hardware
boot
The
hardware
boot
display
shows
system
data
when
power
is
first
applied
to
the
node
as
the
node
searches
for
a
disk
drive
to
boot.
If
this
display
remains
active
for
longer
than
3
minutes,
there
might
be
a
problem.
The
cause
might
be
a
hardware
failure
or
the
software
on
the
hard
disk
drive
is
missing
or
damaged.
Refer
to
the
topic
on
determining
a
hardware
boot
failure.
Node
rescue
request
If
software
is
lost,
you
can
use
the
node
rescue
process
to
copy
all
software
from
another
node.
The
node-rescue-request
display
shows
that
a
request
has
been
made
to
exchange
the
software
on
this
node.
The
SAN
Volume
Controller
software
is
preinstalled
on
all
SAN
Volume
Controller
nodes.
This
software
includes
the
operating
system,
the
application
software,
and
the
SAN
Volume
Controller
publications.
It
is
normally
not
necessary
to
replace
the
software
on
a
node,
but
if
the
software
is
lost
for
some
reason
(if
the
hard
disk
drive
in
the
node
fails),
it
is
possible
to
copy
all
the
software
from
another
node
connected
to
the
same
fibre-channel
fabric.
This
process
is
known
as
node
rescue.
Power
failure
The
SAN
Volume
Controller
runs
on
battery
power
when
main
power
is
lost.
The
Power
failure
display
shows
that
the
SAN
Volume
Controller
is
running
on
battery
power
because
main
power
has
been
lost.
All
I/O
operations
have
stopped.
The
node
is
saving
cluster
metadata
and
node
cache
data
to
the
internal
disk
drive.
When
the
progress
bar
reaches
zero,
the
node
powers
off.
Note:
When
input
power
is
restored
to
the
uninterruptible
power
supply,
the
SAN
Volume
Controller
turns
on
without
the
front
panel
power
button
being
pressed.
