The
upgrade
kits
contain
two
DS4300
controller
CRUs,
with
cache
memory
battery
installed,
and
one
power
supply.
You
must
purchase
additional
SFPs
and
fibre
channel
cables
separately
to
make
fibre
channel
connections
to
the
host
ports
on
the
second
DS4300
controller.
Use
the
following
procedure
for
both
upgrade
kits.
Steps
for
upgrading
from
DS4300
Model
6LU/6LX
to
Model
60U/60X
Before
you
begin:
v
Schedule
downtime
for
the
upgrade.
v
If
you
purchase
additional
storage
capacity
at
the
same
time
as
the
controller
upgrade
kit,
do
not
connect
the
new
drives
or
storage
expansion
enclosures
to
the
DS4300
controllers
until
you
complete
the
following
tasks:
–
Finish
the
upgrade
process
–
Verify
that
the
upgraded
storage
subsystem
is
in
optimal
state
v
If
you
have
premium
features
enabled
in
the
existing
DS4300
storage
subsystem,
ensure
that
you
have
access
to
the
premium
features
key
files
before
you
begin
the
upgrade
process.
You
will
need
to
re-enable
your
premium
features
during
the
process.
v
Ensure
that
you
have
installed
the
latest
version
of
DS4000
Storage
Manager.
For
more
information,
see
the
IBM
DS4000
Storage
Manager
Installation
and
Support
Guide
for
your
operating
system,
or
see
the
following
Web
site:
www-1.ibm.com/servers/storage/support/disk/
v
Use
the
Storage
Manager
Client
to
determine
whether
the
system
is
in
an
optimal
state.
If
it
is
not,
fix
the
problem
to
return
the
system
to
an
optimal
state
before
you
attempt
the
upgrade.
v
After
the
new
controllers
complete
the
boot
process,
the
WWNN
of
the
DS4300
controllers
will
change.
If
you
have
any
applications
that
rely
on
the
previous
WWNNs,
such
as
FC
switch
zoning
definitions,
you
must
update
the
applications
with
the
new
WWNNs.
Complete
the
following
steps
to
upgrade
from
DS4300
Model
6LU/6LX
to
Model
60U/60X,
using
either
the
standard
or
the
Turbo
option
upgrade
kit:
1.
In
the
Storage
Manager
Client,
open
a
management
connection
to
the
DS4300
that
you
are
upgrading.
2.
Save
the
storage
subsystem
profile
to
a
disk
location
that
is
not
in
the
DS4300
that
you
are
upgrading.
In
the
Subsystem
Management
window,
select
View
—>
Storage
Subsystem
Profile
.
When
the
Storage
Subsystem
Profile
window
opens,
click
Save
As
.
The
Save
Profile
window
opens.
Select
an
appropriate
directory
and
choose
a
file
name
for
the
profile,
then
click
Save
.
Click
Close
to
close
the
Storage
Subsystem
Profile
window.
3.
Complete
any
necessary
server
preparation
tasks,
because
the
disks
will
not
be
available
during
the
upgrade
process.
For
example,
stop
all
programs,
services
or
processes
in
the
host
servers
that
access
the
logical
drives.
Note:
Make
sure
that
you
stop
any
background
programs,
services
or
processes
that
write
data
to
the
logical
drives.
For
example,
Microsoft
MSCS
periodically
writes
to
the
Quorum
disk.
4.
Stop
I/O
to
the
storage
subsystem.
5.
Unmount
any
mapped
LUNs
from
