Important:
To
ensure
proper
operation
when
you
connect
an
EXP100
expansion
unit
to
a
DS4300
storage
server,
you
must
perform
the
required
software
and
firmware
support
code
upgrades
to
enable
DS4300
support
for
the
EXP100.
v
Upgrade
the
DS4000
Storage
Manager
host
software
in
the
host
servers
and
the
management
station
to
version
8.41
or
later.
(It
is
recommended
that
you
update
DS4000
Storage
Manager
to
version
9.1.)
See
the
IBM
TotalStorage
DS4000
Storage
Manager
Installation
and
Support
Guide
for
your
operating
system.
v
Upgrade
the
controller
firmware
and
NVSRAM
and
the
ESM
firmware
to
the
required
levels.
See
the
IBM
TotalStorage
DS4000
EXP100
Storage
Expansion
Unit
Installation,
User’s,
and
Maintenance
Guide
for
firmware
requirements
and
instructions
on
how
to
perform
these
upgrades.
Attention:
Do
not
upgrade
your
controller
firmware
to
version
5.41.5x.xx
(or
to
version
6.11.xx.xx
or
higher)
if
your
storage
server
is
connected
to
an
EXP100
with
ESM
firmware
version
953x
or
earlier.
When
the
DS4300
storage
server
is
connected
to
a
DS4000
EXP100,
the
DS4300
must
not
have
fibre
channel
drives
inserted
in
its
slots.
When
connected
to
a
DS4000
EXP100,
all
the
slots
in
the
DS4300
storage
server
must
have
blank
drive
trays
to
ensure
proper
cooling.
Important:
The
DS4300
with
Turbo
storage
server
currently
supports
the
concurrent
attachment,
or
intermixing,
of
fibre
channel
and
Serial
ATA
storage
expansion
units
in
a
single
DS4300
with
Turbo
storage
server
configuration.
To
enable
FC/SATA
intermixing
with
the
DS4300
with
Turbo
storage
server,
you
must
purchase
the
FC/SATA
Intermix
premium
feature
and
perform
the
required
DS4000
Storage
Manager
and
firmware
upgrades
to
support
FC/SATA
intermixing.
Check
with
your
IBM
support
representative
for
additional
DS4300
model
support
for
FC/SATA
intermixing
in
the
future.
Use
the
status
LEDs,
Symptom-to-FRU
list,
and
the
storage
management
software
to
diagnose
problems.
See
“Monitoring
status
through
software”
on
page
70
and
“Checking
the
LEDs”
on
page
71.
To
diagnose
a
cluster
system,
use
the
cluster
problem
determination
procedure
found
in
the
IBM
TotalStorage
DS4000
Problem
Determination
Guide
.
Note:
If
power
was
just
applied
to
the
controller
unit,
the
green
and
amber
LEDs
might
turn
on
and
off
intermittently.
Wait
until
the
controller
unit
finishes
powering
up
before
you
begin
to
check
for
faults.
