Code
Message
Description
Action
E430B
SAS
disk
(@<Bus>,<ID>,<LUN>):
SAS
Address
xx:xx:xx:xx:xx:xx:xx:xx,
LUN#<LUN>
The
blade
firmware
was
not
able
to
read
a
disk.
The
error
might
be
due
to
connectivity,
SAS
switches,
disk,
attached
storage,
hardware,
blade
firmware,
or
SAS
Expansion
Card
firmware
problem(s).
Output:
The
<Bus>,
<ID>,
and
<LUN>
values
are
determine
the
disk’s
Open
Firmware
Device
Tree
unit
address
(see
IEEE
1275).
The
xx:xx:xx:xx:xx:xx:xx:xx
value
determines
the
SAS
address
of
device
containing
the
disk.
If
a
disk
is
a
physical
device
then
the
SAS
address
is
the
identifier
of
disk
itself.
If
a
disk
is
a
volume
within
a
RAID
controller
then
the
SAS
address
is
identifier
of
the
RAID
controller.
The
<LUN>
is
disk
logical
unit
number.
Note:
though
the
logical
unit
number
is
printed
explicitly
and
within
the
unit
address,
it
is
always
the
same
value.
Sample
error
message:
E430B
SAS
disk
(@0,3,0):
SAS
Address
50:01:0b:90:00:42:8a:ee,
LUN#0
The
Open
Firmware
Device
Tree
node
name
is
/axon@10000000000/plb5/
plb4/pcix@4000004600000000/scsi@2/
disk@0,3,0.
The
disk
is
located
at
Bus#0,
ID#3,
and
LUN#0.
The
SAS
address
of
device
containing
disk
is
50:01:0b:90:00:42:8a:ee.
The
logical
unit
number
is
zero.
1.
Ensure
the
remote
disk
is
operating
correctly.
Try
to
read
the
disk
from
another
blade
server
in
the
same
BladeCenter
unit.
This
verifies
SAS
topology
and
remote
storage
operation
as
well.
2.
Ensure
the
remote
storage
is
configured
correctly.
If
configured
as
a
RAID
array,
check
the
RAID
configuration.
See
the
documentation
that
comes
with
the
storage
for
further
information.
3.
Ensure
the
operation
of
the
entire
SAS
topology.
This
includes
checking
any
SAS
switches,
SAS
cables,
connectors,
etc.
See
the
documentation
that
comes
with
each
component
of
the
SAS
topology.
4.
Reboot
the
blade.
5.
Power
down
then
remove
and
reinstall
the
blade
server
in
the
BladeCenter
unit.
6.
Remove
and
reinstall
the
SAS
Expansion
Card.
7.
Ensure
the
SAS
Expansion
Card
firmware
and
blade
firmware
version
are
at
the
correct
level.
8.
If
the
error
started
after
a
SAS
Expansion
Card
firmware
upgrade
or
a
blade
server
firmware
upgrade,
consider
a
rollback
to
the
previous
firmware
versions.
Check
with
the
documentation
at
http://www.ibm.com/systems/
bladecenter/support/
to
verify
whether
rollback
is
possible.
9.
Plug
the
SAS
Expansion
Card
into
another
blade
server.
If
the
problem
persists,
the
SAS
Expansion
Card
may
need
replacement.
10.
Plug
a
different
SAS
Expansion
Card
into
the
blade
server.
If
the
problem
persists,
the
blade
server
system
board
may
need
replacement.
