1.
After
the
emergency
situation
is
over
or
power
is
restored,
check
the
storage
subsystem
for
damage.
If
there
is
no
visible
damage,
continue
with
step
2;
otherwise,
have
your
system
serviced.
2.
After
you
have
checked
for
damage,
ensure
that
the
power-supply
switches
are
off;
then
plug
in
the
storage-server
power
cords.
3.
Complete
step
2
on
page
92
to
determine
the
proper
power-on
sequence
for
your
system.
4.
Complete
steps
3
and
4
on
page
93
to
turn
on
power
to
the
devices
in
your
system
and
to
check
the
status
of
the
storage
subsystem.
Restoring
power
after
an
over-temperature
shutdown
Use
the
following
procedure
to
restart
the
storage
subsystem
after
an
unexpected
shutdown
due
to
an
over-temperature
condition:
1.
Make
sure
that
the
power-supply
switches
on
the
back
of
the
storage
subsystem
are
turned
off.
2.
Do
whatever
is
necessary
to
cool
the
unit
(replace
the
fans,
use
external
fans
to
cool
the
room,
and
so
on).
3.
Check
all
components
and
cables
for
visible
damage.
Do
not
start
the
storage
subsystem
if
you
find
evidence
of
damage.
4.
Complete
step
2
on
page
92
to
determine
the
proper
power-on
sequence
for
your
system.
5.
When
the
internal
temperature
of
the
storage
subsystem
is
below
35°C
(95°F),
complete
steps
3
and
4
on
page
93
to
turn
on
power
to
the
devices
in
your
system
and
to
check
the
status
of
the
storage
subsystem.
Monitoring
status
through
software
Use
the
storage-management
software
to
monitor
the
status
of
the
storage
subsystem.
Run
the
software
constantly,
and
check
it
frequently.
Notes:
1.
You
can
only
monitor
storage
subsystems
that
are
within
the
management
domain
of
the
storage-management
software.
2.
If
you
do
not
install
the
Event
Monitor
service
as
part
of
the
storage-management
software
installation,
the
Enterprise
Management
window
of
the
storage-management
software
must
remain
open.
(If
you
close
the
window,
you
will
not
receive
any
alert
notifications
from
the
managed
storage
subsystems.)
For
more
information,
see
the
Enterprise
Management
online
Help.
The
storage-management
software
provides
the
best
way
to
diagnose
and
repair
storage-server
failures.
The
software
can
help
you
do
the
following:
v
Determine
the
nature
of
the
failure
v
Locate
the
failed
component
v
Determine
the
recovery
procedures
to
repair
the
failure
Although
the
storage
subsystem
has
fault
LEDs,
these
lights
do
not
necessarily
indicate
which
component
has
failed
or
needs
to
be
replaced,
or
which
type
of
recovery
procedure
you
must
perform.
In
some
cases
(such
as
loss
of
redundancy
in
various
components),
the
fault
LED
does
not
turn
on.
Only
the
storage-management
software
can
detect
the
failure.
