system. Cross-referenced information is given in the firmware information on the IBM Support Web site at http://www.ibm.com/support, and in the readme file for the firmware image. Updating the firmware code for the blade server service processor To apply the latest firmware code for the blade server service processor, flash the service processor. Download the latest firmware code for the blade server service processor from the IBM Support Web site at http://www.ibm.com/support. Use the BladeCenter management-module Web interface to flash the service processor. Follow the update instructions on the IBM Support Web site. Important: To avoid problems and to maintain proper system performance, always make sure that the blade server firmware code and service processor code levels are consistent for all blade servers within the BladeCenter unit. Notes: v For additional information about the hardware and firmware requirements for other BladeCenter components, see the IBM BladeCenter and BladeCenter T Serial Over LAN Setup Guide. v Go to the IBM Support Web site, http://www.ibm.com/support, for the latest information about upgrading the device drivers, firmware code, and basic input/output system (BIOS) code for other BladeCenter components. Updating and managing the system flash using Linux service aids This section describes how to update and verify the system flash using Linux service aids. Updating the system flash using Linux The Linux service aid for managing the system flash is separate from the operating system installation and is available for download from the following Web site: http://techsupport.services.ibm.com/server/lopdiags/. Note: The update_flash command can only be performed if the update_flash service aid has been installed on the blade server for the appropriate version of Linux. Complete the following steps to update the system firmware code: 1. Obtain the flash image that you want to update and place it in the /etc/microcode directory (create the directory, if it does not exist). 2. Issue the following command: update_flash -f /etc/microcode/ After the system reboots successfully and once you are satisfied with the functionality of the new image, commit the update using the following Linux command: update_flash -c This will copy your new image from the TEMP side to PERM side of flash. Verifying the system firmware levels using Linux To verify the system firmware levels on the PERM and TEMP sides, enter the following command at the Linux prompt (the entire command must be entered on one line): for file in `ls /proc/device-tree/openprom/*bank*`; do echo $file; Chapter 5.

system
flash
using
Linux
service
aids
This
section
describes
how
to
update
and
verify
the
system
flash
using
Linux
service
aids.
Updating
the
system
flash
using
Linux
The
Linux
service
aid
for
managing
the
system
flash
is
separate
from
the
operating
system
installation
and
is
available
for
download
from
the
following
Web
site:
Note:
The
update_flash
command
can
only
be
performed
if
the
update_flash
service
aid
has
been
installed
on
the
blade
server
for
the
appropriate
version
of
Linux.
Complete
the
following
steps
to
update
the
system
firmware
code:
1.
Obtain
the
flash
image
that
you
want
to
update
and
place
it
in
the
/etc/microcode
directory
(create
the
directory,
if
it
does
not
exist).
2.
Issue
the
following
command:
update_flash
-f
/etc/microcode/<update_image_name>
After
the
system
reboots
successfully
and
once
you
are
satisfied
with
the
functionality
of
the
new
image,
commit
the
update
using
the
following
Linux
command:
update_flash
-c
This
will
copy
your
new
image
from
the
TEMP
side
to
PERM
side
of
flash.
Verifying
the
system
firmware
levels
using
Linux
To
verify
the
system
firmware
levels
on
the
PERM
and
TEMP
sides,
enter
the
following
command
at
the
Linux
prompt
(the
entire
command
must
be
entered
on
one
line):
for
file
in
`ls
/proc/device-tree/openprom/*bank*`;
do
echo
$file;
