Channel
or
SATA
expansion
enclosures),
you
need
to
upgrade
the
controller
firmware
to
version
06.1x.xx.xx
and
enable
the
FC/SATA
Intermix
premium
feature
before
you
attach
the
other
type
of
expansion
enclosure.
v
If
you
are
upgrading
a
DS4300
or
DS4500
subsystem
from
controller
firmware
version
05.41.1x.xx
to
06.1x.xx.xx,
you
cannot
upgrade
directly
from
05.41.1x.xx
to
06.1x.xx.xx.
Instead,
you
must
first
upgrade
to
the
intermediate
controller
firmware
version
05.41.5x.xx.
In
this
case,
contact
your
IBM
support
representative
to
obtain
the
necessary
05.41.5x.xx
controller
firmware
files.
v
The
EXP100
ESM
now
supports
Full
High
Availability
(FHA).
With
this
functionality,
in
the
event
of
ESM
or
Fibre
Channel
cabling
failure,
the
drives
that
belong
to
the
failed
ESM
will
fail-over
to
the
surviving
ESM,
whether
or
not
the
ESM
remains
inserted
in
the
EXP100
drive
enclosure
chassis.
In
either
case,
with
FHA,
the
controller
can
recognize
any
of
the
drives
that
were
managed
by
the
failed
ESM.
v
Upgrading
the
EXP100
ESM
firmware
from
953x
to
9554
requires
the
controller
firmware
version
05.41.1x.xx.
It
is
not
possible
to
upgrade
the
EXP100
ESM
from
any
pre-9554
version
to
the
9554
version
if
the
controller
firmware
of
the
attached
DS4000
storage
subsystem
is
version
05.41.5x.xx
or
version
05.42.xx.xx.
In
addition,
do
not
insert
an
ESM
with
firmware
version
9554
into
an
EXP100
that
contains
an
ESM
with
firmware
version
953x
installed.
If
you
do,
the
Storage
Manager
Subsystem
Management
window
will
show
the
EXP100
with
all
slots
empty.
v
Upgrading
controller
firmware
from
version
05.xx.xx.xx
to
version
06.xx.xx.xx
requires
that
there
be
no
I/O
activity
to
the
DS4000
storage
subsystems.
You
must
schedule
down
time
for
the
upgrade.
However,
upgrading
controller
firmware
from
one
06.xx.xx.xx
version
to
a
different
06.xx.xx.xx
version
does
not
require
that
I/O
activity
be
stopped.
Note:
This
release
also
includes
the
following
controller
firmware:
v
6.10.xx.xx
(DS4300,
DS4400
and
DS4500
storage
subsystems)
v
6.14.xx.xx
(DS4800
storage
subsystem)
Fourth
release:
The
fourth
release
of
the
DS4000
controller
firmware/NVSRAM
supports
both
the
EXP100
400
GB
SATA
CRU
option
and
the
250
GB
CRU
option
for
attachment
to
the
DS4100,
DS4300,
DS4400,
DS4500,
and
DS4800
storage
subsystems.
IBM
recommends
that
you
upgrade
the
DS4000
controller
firmware
and
EXP100
ESM
firmware
to
the
versions
in
this
release
to
take
advantage
of
quality
enhancements
and
to
ensure
the
compatibility
of
ESM
and
SATA
drive
CRUs
in
the
future.
The
latest
controller
firmware
version
for
this
release
is
06.12.16.xx
or
later
(for
the
DS4100,
DS4300,
DS4400,
and
DS4500)
and
06.15.16.xx
or
later
for
the
DS4800.
The
associated
EXP100
ESM
firmware
version
is
956x.
This
release
has
the
following
characteristics:
v
Support
of
the
400
GB
drive
option/CRU
in
addition
to
the
250
GB
drive
CRU.
v
Upgrading
the
EXP100
ESM
firmware
from
version
953x
to
version
956x
is
not
supported.
You
must
schedule
down
time
to
upgrade
the
ESM
firmware
to
an
intermediate
version,
9554,
before
you
can
upgrade
to
the
956x
version.
