b.
You
must
complete
this
step
before
you
insert
the
upgrade
controller
into
the
DS4000
storage
subsystem.
For
more
information,
see
the
instructions
the
appropriate
IBM
DS4000
Storage
Manager
version
9.1x
Installation
and
Support
Guide
.
c.
If
you
have
created
a
DHCP/BootP
record
for
controller
A,
you
must
add
one
for
controller
B.
Otherwise,
you
might
not
be
able
to
manage
controller
B
using
the
Ethernet
network.
19.
Connect
the
power
cord
to
the
ac
connector
of
the
newly
added
power
supply
CRU.
20.
Plug
the
power
cord
into
a
properly
grounded
electrical
outlet.
21.
Turn
on
the
power
supply
switches.
Make
sure
that
the
green
Power
LED
on
the
new
power
supply
CRU
is
on,
and
that
the
amber
Fault
LED
is
off.
v
If
the
Power
LED
is
off,
the
power-supply
CRU
might
not
be
installed
correctly.
Remove
it,
and
then
reinstall
it.
v
Ensure
that
the
electrical
outlet
is
hot.
v
If
the
Fault
LED
is
on,
or
if
the
Power
LED
stays
off,
contact
your
IBM
support
representative.
Note:
To
maintain
power
redundancy
on
the
DS4300
dual-controller
storage
subsystem
(Model
60U/60X),
plug
the
right
and
the
left
power
supplies
into
two
independent
external
power
circuits
through
ac
distribution
units
(inside
a
rack
cabinet
or
directly
into
external
receptacles).
Similarly,
plug
the
right
and
left
power
supplies
of
any
attached
DS4000
EXP
storage
expansion
enclosures
into
the
same
two
independent
external
power
circuits
as
the
DS4300
storage
subsystem.
See
Figure
72
on
page
86
for
an
example
of
redundant
power
cabling.
22.
Wait
a
few
minutes
for
the
new
controllers
to
complete
the
boot
process.
23.
If
applicable,
update
the
fibre
channel
switch
fabric-zone
definitions
with
the
newly
generated
controller
World
Wide
Node
Name
(WWNN).
Note:
If
you
have
any
other
applications
that
rely
on
the
previous
DS4300
controller
WWNN,
then
you
must
also
update
the
applications
with
the
new
WWNNs.
24.
Using
the
Storage
Manager
client,
open
a
management
connection
to
the
DS4300
storage
subsystem.
25.
Verify
that
the
storage
subsystem
does
not
have
any
errors
(beside
the
battery
failed/charging
error).
If
there
are
missing
LUNs,
configurations,
failed
fibre-channel
hard
drives
or
fibre-channel
hard
drives
that
display
the
“need
attention”
icon,
contact
your
IBM
support
representative.
26.
Set
the
enabled
premium
features
back
into
an
enabled
and
optimal
state,
using
the
existing
premium
features
key
files
for
the
RAID
controller
that
you
removed
from
the
original
storage
subsystem.
Note:
Before
you
complete
this
step,
the
premium
features
might
display
as
enabled,
but
they
will
be
“out
of
compliance.”
27.
If
this
is
the
Turbo
upgrade
option,
use
the
Storage
Manager
Client
to
verify
the
firmware
and
NVSRAM.
If
the
current
versions
are
earlier
than
the
versions
that
are
included
on
the
Turbo
Option
CD,
reload
the
firmware
and
NVSRAM
to
the
CD
versions.
Then,
check
the
IBM
Web
site
for
any
firmware
or
NVSRAM
updates.
