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:

2. Issue the following command:

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;
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.
make sure that the blade server firmware code and service processor
code levels are consistent for all blade servers within the BladeCenter
unit.

/etc/microcode directory (create the directory, if it does not exist).
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:
