Important:
1.
If
the
version
of
the
ESM
firmware
in
your
EXP100
storage
expansion
enclosure
is
not
956x
or
later,
you
must
schedule
time
to
upgrade
the
EXP100
ESM
firmware
to
the
latest
version
posted
on
the
Web
as
soon
as
possible.
This
is
to
ensure
that
you
take
advantage
of
the
quality
enhancements
and
the
compatibility
and
availability
of
the
EXP100
ESM
and
SATA
drive
FRUs/CRUs
in
the
future.
2.
If
the
EXP100
ESM
firmware
is
953x
or
earlier,
you
must
schedule
down
time
for
ESM
firmware
upgrades.
In
addition,
you
must
upgrade
the
EXP100
ESM
to
the
intermediate
version
of
9554
first
before
upgrading
the
ESM
firmware
to
956x
or
later.

SATA

cannot
be
interchanged
with
the

that
are
supported
in
other
DS4000
series
storage
products.
If
you
need
further
assistance,
contact
IBM
technical
support,
your
IBM
reseller,
or
your
IBM
representative
to
find
out
which
EXP100
CRU
is
compatible
with
the
ESM
firmware
of
your
existing
ESM
module.
First
release:
The
first
release
of
the
DS4000
controller
firmware
and
NVSRAM
was
for
DS4300
and
DS4500
storage
subsystems
only,
to
support
the
attachment
of
the
EXP100
storage
expansion
enclosure.
The
controller
firmware
version
is
05.41.1x.xx,
and
the
associated
EXP100
ESM
firmware
version
is
953x.
This
release
has
the
following
characteristics:
v
The
coexistence
(intermix)
of
Fibre
Channel
drives
and
SATA
drives
in
a
DS4000
storage
subsystem
is
not
supported.
This
requires
that
the
DS4000
storage
subsystem
go
through
a
special
controller
upgrade
process
to
load
the
05.41.1x.xx
firmware,
because
the
DS4000
storage
subsystem
will
not
see
any
EXP100
enclosures
or
SATA
drives
until
the
controller
firmware
version
05.41.1x.xx
is
loaded.
v
The
EXP100
ESM
has
only
Limited
High
Availability
(LHA)
support.
Each
ESM
physically
controls
seven
even-numbered
or
odd-numbered
drives.
If
the
Fibre
Channel
cabling
to
an
ESM
fails,
the
drives
that
belong
to
the
ESM
with
the
cabling
failure
will
fail-over
to
the
surviving
ESM
only
if
the
ESM
remains
inserted
in
the
EXP100
drive
enclosure
chassis.
If
the
ESM
fails
or
is
removed
from
the
chassis,
the
controller
will
not
be
able
to
recognize
any
of
the
drives
that
were
managed
by
the
failed
or
removed
ESM
and
will
mark
them
as
failed.
Second
release:
The
second
release
of
the
DS4000
controller
firmware/NVSRAM
added
support
for
DS4100
storage
subsystems,
in
addition
to
the
DS4500
and
the
DS4300
storage
subsystems,
for
attachment
of
the
EXP100.
