Set
the
RAID
controller
on
a
dry,
level
surface
away
from
magnetic
fields.
Save
the
packing
material
and
documentation
in
case
you
need
to
return
the
RAID
controller.
10.
If
DHCP/BootP
was
used
to
automatically
set
the
IP
address
of
the
controller,
record
the
MAC
address
of
the
upgrade
controller
and
modify
the
existing
DHCP/BootP
record
of
the
RAID
controller
to
be
upgraded
with
the
new
MAC
address.
Failure
to
modify
the
DHCP/BootP
record
will
result
in
problems
trying
to
manage
the
storage
subsystem
using
the
existing
IP
address.
This
step
must
be
performed
before
you
insert
the
upgrade
controller
into
the
DS4000
storage
subsystem.
11.
Install
the
new
RAID
controller,
as
follows:
a.
Slide
the
RAID
controller
all
the
way
into
the
empty
slot.
b.
Close
both
levers
until
the
latch
locks
into
place.
Attention:
When
you
replace
the
old
RAID
controller,
the
storage-management
software
automatically
synchronizes
the
firmware
between
the
existing
controller
and
the
new
controller.
After
you
replace
a
controller,
always
use
the
storage-management
software
to
verify
the
firmware
levels
and
nonvolatile
storage
random
access
memory
(NVSRAM)
files.
12.
Insert
the
SFPs
according
to
the
instructions
in
“Installing
SFP
modules”
on
page
33.
13.
Connect
the
fibre-channel
cables
to
their
original
locations,
according
to
the
instructions
in
Chapter
3,
“Cabling
the
storage
subsystem,”
on
page
29.
14.
Wait
approximately
one
minute,
and
then
check
the
green
Host
Loop
LED,
green
Expansion
Loop
LED,
and
amber
Fault
LED
on
the
new
RAID
controller.
Note:
If
the
Expansion
Loop
LED
is
off,
the
RAID
controller
might
not
be
inserted
correctly.
Remove
the
RAID
controller
and
reinsert
it.
15.
Bring
the
controller
online
by
completing
the
following
steps:
a.
In
the
Physical
View
of
the
Subsystem
Management
window,
right-click
the
controller
icon
and
select
Place-->Online
.
b.
Click
Yes
when
the
Controller
Online
Confirmation
window
opens.
16.
Check
that
the
controller
is
online.
Use
either
of
the
two
following
methods:
v
Use
the
Storage
Manager
client
to
verify
that
the
controller
is
online
(up)
and
running
by
selecting
the
menu
option
to
display
the
properties
of
the
controller
that
has
just
been
replaced.
If
the
controller
is
not
up,
you
will
get
a
controller-connection
error
window
instead
of
the
Controller
Properties
window.
Wait
a
minute
and
retry
until
you
get
the
properties
window.
v
Check
the
LEDs
at
the
back
of
the
controller.
All
Fault
LEDs
should
be
off
and
the
Host
Loop
and
Expansion
Loop
LEDs
should
be
on.
17.
If
the
Fault
LED
is
on,
the
Host
Loop
LED
and
the
Expansion
Loop
LED
stay
off,
or
any
other
Fault
LED
is
on,
see
the
Storage
Manager
client
for
problem
determination.
Note:
The
battery
LED
may
be
flashing
indicated
battery
charging
is
in
progress.
18.
Repeat
step
4
through
step
17
for
the
second
controller.
However,
do
not
continue
with
this
step
if
the
new
controller
is
not
in
online
and
optimal
state
due
to
reasons
other
than
battery
charging
and
controller
cache
memory
not
matching.
19.
Enable
controller
caching
by
completing
the
following
steps:
