For
the
DS4100
base
storage
server:
See
the
DS4000
Storage
Manager
client
online
help
for
instructions
on
bringing
the
controller
online.
The
RAID
controller
replacement
procedure
for
the
DS4100
base
storage
server
is
completed.
29.
For
the
DS4100
single-controller
storage
server:
Because
the
replacement
RAID
controller
has
a
different
WWNN
that
the
original
RAID
controller,
you
must
perform
the
following
tasks
in
order
to
bring
the
DS4100
single-controller
storage
server
to
running
(optimal)
state
after
you
replace
the
RAID
controller.
v
Reboot
the
host
server
that
has
mapped
logical
drives
from
the
DS4100
single-controller
storage
server.
Rebooting
the
host
server
enables
the
multipath
fail-over
to
recognize
the
logical
drives
under
the
new
WWNN.
In
addition,
if
your
multipath
driver
uses
the
WWNN
of
the
controller
as
part
of
the
LUN
identification,
you
may
have
to
reconfigure
the
LUN
fail-over/failback
path
information.
v
Use
DS4000
Storage
Manager
to
rediscover
the
new
RAID
controller.
To
rediscover
the
new
RAID
controller,
remove
the
existing
DS4100
single-controller
storage
server
entry
in
the
management
domain
of
the
DS4000
Storage
Manager
client
Enterprise
Management
Window
(EMW),
and
then
add
the
DS4100
single-controller
storage
server
back
into
the
management
domain
using
the
in-band
or
out-of-band
management
method.
See
step
v
Re-enable
the
premium
feature
keys.
After
you
replace
the
RAID
controller
in
a
DS4100
single-controller
storage
server,
all
of
the
enabled
premium
feature
keys
are
displayed
as
being
out-of-compliance.
Use
the
existing
key
files
to
re-enable
the
premium
feature
keys.
v
If
you
create
zones
using
the
WWNN,
update
your
zoning
definitions
with
the
new
WWNN
for
the
replacement
RAID
controller.
If
you
are
able
to
to
make
a
management
connection
with
DS4000
Storage
Manager
to
the
replacement
RAID
controller,
then
the
RAID
controller
replacement
procedure
for
the
DS4100
single-controller
storage
server
is
complete.
If
none
of
these
actions
enables
you
to
make
a
management
connection
with
DS4000
Storage
Manager
to
the
replacement
RAID
controller,
then
call
IBM
support
for
help.
Manually
upgrading
the
firmware
for
the
DS4100
single-controller
storage
server
You
will
need
the
most
recent
printout
of
your
storage
subsystem
profile
to
perform
this
procedure.
If
you
do
not
have
a
printout
available,
contact
IBM
technical
support
to
determine
the
controller
firmware
and
NVSRAM
version
numbers
recorded
in
your
storage
subsystem
profile.
Attention:
This
procedure
is
not
self-contained.
Perform
this
procedure
only
if
directed
to
do
so
in
step
At
the
end
of
this
procedure,
continue
with
step
in
the
RAID
controller
replacement
procedure.
Be
sure
that
the
BOOTP
server
configuration
includes
the
MAC
address
you
recorded
for
the
new
controller.
