Solving
undetermined
problems
Note:
When
you
are
diagnosing
a
problem
in
the
blade
server,
you
must
determine
whether
the
problem
is
in
the
blade
server
or
in
the
BladeCenter
unit.
v
If
all
of
the
blade
servers
have
the
same
symptom,
it
is
probably
a
BladeCenter
unit
problem;
for
more
information,
see
the
Hardware
Maintenance
Manual
and
Troubleshooting
Guide
or
Problem
Determination
and
Service
Guide
for
your
BladeCenter
unit.
v
If
the
BladeCenter
unit
contains
more
than
one
blade
server
and
only
one
of
the
blade
servers
has
the
problem,
troubleshoot
the
blade
server
that
has
the
problem.
If
the
diagnostic
tests
did
not
diagnose
the
failure
or
if
the
blade
server
is
inoperative,
use
the
information
in
this
section.
If
you
suspect
that
a
software
problem
is
causing
failures
(continuous
or
intermittent),
see
“Software
problems”
on
page
37.
Damaged
data
in
CMOS
memory
or
damaged
BIOS
code
can
cause
undetermined
problems.
To
reset
the
CMOS
data,
remove
and
replace
the
battery
to
override
the
power-on
password
and
clear
the
CMOS
memory;
see
“Removing
the
battery”
on
page
70.
If
you
suspect
that
the
BIOS
code
is
damaged,
see
“Recovering
from
a
BIOS
update
failure”
on
page
