Try
following
steps
in
order
to
fix
the
problem:
1.
Ensure
the
remote
disk
is
operating
correctly.
Try
to
read
the
disk
from
another
blade
server
in
the
same
BladeCenter
unit.
This
verifies

and
remote

operation
as
well.
Note:
Concurrent
access
to
a
disk
from
a
different
blade
server
might
corrupt
the
disk’s
file
system.
Check
with
a
system
administrator
before
attempting
this
step.
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
bladecenter/support/
to
verify
whether
rollback
is
possible.
