local
SAS
disk,
hardware,
blade

or
SAS
Expansion

problems.
1.
Try
to
boot
an
operating
system
and
acess
the
LSI
Integrated
RAID
disks
using
that
operating
system's
tools
(for
example,
CFGGEN).
This
verifies
the
LSI
Integrated
RAID
operation.
Pay
attention
to
the
tools
output
and
operating
system
diagnostic
messages.
2.
Ensure
the
operation
of
the
entire
SAS
topology
in
the
BladeCenter
S
unit.
This
includes
checking
any
SAS
switches,
Storage
Modules,
hard
drives,
and
so
on.
See
the
documentation
that
comes
with
each
component
of
the
SAS
topology.
3.
Reboot
the
blade.
4.
Power
down
then
remove
and
reinstall
the
blade
server
in
the
BladeCenter
unit.
5.
Remove
and
reinstall
the
SAS
Expansion
Card.
6.
Ensure
the
SAS
Expansion
Card
firmware
and
blade
firmware
version
are
at
the
correct
level.
7.
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.
8.
Plug
the
SAS
expansion
card
into
another
blade
server.
If
the
problem
persists,
the
SAS
Expansion
Card
may
need
replacement.
9.
Plug
a
different
SAS
expansion
card
into
the
blade
server.
If
the
problem
persists,
the
blade
server
system
board
may
need
replacement.
