With
the
storage
expansion
unit
installed
on
your
blade
server,
you
can
install
up
to
two
hot-swap
SCSI
hard
disk
drives
in
the
expansion
unit
and
configure
them
for
embedded
mirroring
(RAID
level
1).
Each
SCSI
device
must
have
a
unique
SCSI
ID.
This
ID
enables
the
SCSI
controller
in
the
expansion
option
to
identify
the
device
and
ensure
that
different
devices
on
the
same
SCSI
channel
do
not
attempt
to
transfer
data
simultaneously.
The
SCSI
IDs
for
the
hard
disk
drives
in
the
expansion
unit
are
permanent
(not
configurable).
Table

lists
the
SCSI
IDs
for
the
hard

drives
that
are
installed
in

expansion
unit.

drive”
for

hard

drives.

Use

See
the

Installing
a
SCSI
hot-swap
hard
disk
drive
If
you
have
installed
a
SCSI
storage
expansion
unit
on
the
blade
server,
you
can
install
up
to
two
SCSI
hot-swap
hard
disk
drives
in
the
bays
in
the
expansion
unit.
If
a
hot-swap
hard
disk
drive
in
the
expansion
unit
fails,
you
can
replace
it
without
turning
off
the
blade
server.
Therefore,
you
have
the
advantage
of
continuing
to
operate
your
blade
server
while
a
hard
disk
drive
in
this
unit
is
removed
or
installed.
Each
hot-swap
drive
has
two
indicator
LEDs.
If
the
amber
hard
disk
drive
status
LED
for
a
drive
is
lit
continuously,
that
drive
is
faulty
and
must
be
replaced.
Each
hot-swap
drive
that
you
plan
to
install
must
be
mounted
in
a
hot-swap-drive
tray.
The
drive
must
have
a
Single
Connector
Attachment
(SCA)
connector.
Hot-swap-drive
trays
come
with
hot-swap
drives.
