Recovering
the
system
firmware
code
The
system
firmware
is
contained
in
two
separate
images
in
the
flash
memory
of
the
blade
server:
temporary
and
permanent.
These
images
are
referred
to
as
TEMP
and
PERM,
respectively.
The
system
normally
starts
from
the
TEMP
image,
and
the
PERM
image
serves
as
a
backup.
If
the
TEMP
image
becomes
damaged,
such
as
from
a
power
failure
during
a
flash
update,
you
can
recover
the
TEMP
image
from
the
PERM
image.
If
the
TEMP
image
becomes
damaged,
you
can
see
one
of
two
symptoms:
v
The
system
automatically
starts
from
the
PERM
image.
To
check
whether
the
system
has
started
from
the
PERM
image,
enter:
cat
/proc/device-tree/openprom/ibm,fw-bank
A
P
is
returned.
v
The
system
hangs
or
is
non-responsive
after
the
system
is
started
with
no
checkpoints.
Starting
the
TEMP
image
To
force
the
system
to
start
the
TEMP
image,
complete
the
following
steps:
1.
Turn
off
the
blade
server.
2.
Restart
the
blade
system
management
processor
from
the
management
module.
3.
Turn
on
the
blade
server.
Note:
If
the
blade
server
does
not
restart,
you
must
replace
the
system-board
assembly.
Contact
a
service
support
representative
for
assistance.
Recovering
the
TEMP
image
from
the
PERM
image
To
recover
the
TEMP
image
from
the
PERM
image,
you
must
perform
the
reject
function.
The
reject
function
copies
the
PERM
image
into
the
TEMP
image.
To
perform
the
reject
function,
complete
the
following
steps:
