Note:
The
user
and
operating
system
interfaces
of
the
system
firmware
are
based
on
the
Open
Firmware
standard.
Detailed
system
information
is
provided
through
the
Open
Firmware
device
tree.
You
can
use
the
client
interface
and
Run-Time

and
do
not
follow
the

IBM
periodically
makes
updates
to
both
BMC
and
system
firmware.
These
may
be
downloaded
from
http://www.ibm.com/support/us/en/.
Note:
To
avoid
problems
and
to
maintain
proper
system
performance,
always
make
sure
that
both
the
BMC
firmware
and
the
system
firmware
are
at
the
same
level
for
all
QS22
blade
servers
within
the
BladeCenter
unit.
Updating
steps
Complete
the
following
steps
to
update
the
BMC
and
system
firmware
images:
1.
Check
the
revision
level
of
the
firmware
on
the
blade
server
and
the
level
of
the
updates
on
http://www.ibm.com/support/us/en/.
If
the
level
on
the
Web
site
is
higher
than
the
version
currently
installed,
continue
with
the
updating
steps.
2.
Download
the
firmware
updates.
3.
Power
off
the
blade
server
you
wish
to
update.
4.
Update
the
BMC
firmware
using
the
BMC
update
package
or
the
Advanced
Management
Module.
See
“Updating
the
BMC
firmware”
on
page
17
for
further
information.
5.
Power
on
the
blade
server.
This
boots
it
with
the
new
BMC
firmware.
6.
Update
the
system
firmware
image.
See
“Installing
the
system
firmware”
on
page
20
for
further
information.
7.
The
system
reboots.
This
boots
the
blade
server
with
the
new
system
firmware.
8.
Shut
down
the
blade
server.
Note:
There
may
be
instances
where
you
must
update
the
BMC
firmware
before
updating
the
system
firmware.
Check
the
readme
file
that
comes
with
each
firmware
package
for
more
information.
