Unpredictable
results
can
occur
when
nonmatching
controller
CRUs
are
present
in
the
same
DS4100
chassis.
v
After
the
new
controller
in
a
DS4100
single-controller
storage
server
completes
the
boot
process,
its
WWNN
will
change.
If
you
have
any
applications
that
rely
on
the
previous
WWNNs,
such
as
fibre
channel
switch
zoning
definitions,
you
must
update
the
applications
with
the
new
WWNNs.
v
All
factory-delivered
DS4100
RAID
controllers
are
shipped
with
a
recent
version
of
controller
firmware
loaded
on
the
RAID
controller,
but
that
firmware
version
might
not
match
precisely
the
firmware
version
of
the
failed
RAID
controller
you
have
replaced.
When
you
replace
one
of
the
RAID
controllers
in
the
DS4100
base
storage
server,
the
newly
replaced
controller
will
automatically
be
updated
with
the
controller
firmware
version
of
the
existing
controller
in
the
DS4100
chassis.
However,
when
you
replace
the
RAID
controller
in
the
DS4100
single-controller
storage
server,
if
the
firmware
version
of
the
replacement
RAID
controller
is
determined
to
be
incompatible
with
the
configuration
database
during
the
boot
process,
the
DS4100
single-controller
storage
server
will
enter
a
Stop
State
and
will
not
allow
any
DS4000
Storage
Manager
operations
to
be
performed.
In
this
case,
you
must
manually
upgrade
or
downgrade
the
replacement
RAID
controller
firmware
to
match
the
version
required
by
the
configuration
database.
See

Do
not
use
the
RAID
controller
replacement
procedure
in
this
section
to
upgrade
a
DS4100
single-controller
storage
server
to
a
DS4100
base
storage
server.
Currently
there
is
no
support
for
upgrading
a
DS4100
single-controller
storage
server.
When
such
support
is
available
in
the
future,
the
DS4100
single-controller
storage
server
upgrade
kit
and
the
revised
edition
of
this
document
will
provide
the
upgrade
instructions.
In
a
DS4100
base
storage
server,
you
can
hot
swap
one
controller
while
the
other
is
still
active.
The
figures
in
this
procedure
show
the
base
storage
server.
If
your
storage
server
is
the
single-controller
storage
server,
controller
slot
B
will
have
a
blank
controller
rather
than
the
second
controller
as
shown
in
these
figures.
