Not sure what wiki formatting SF is using now, but for mediawiki, I would just
add this to the end of that section:
'''NOTE:''' It's possible to see an error, "module signed with unknown key"
either when running mknb or booting the newly rebuilt genesis kernel. If this
happens, it is necessary to remove the signature from the kernel module:
<pre>objcopy -R .note.module.sig module.ko new_module.ko</pre>
After this, replace the old module with the new one, rerun 'depmod' and 'mknb'

Hi Christian,
Thanks for the suggestions. Can you be more specific? The following is the
current text. Can you let us know where to add "objcopy -R .note.module.sig
module.ko new_module.ko"? Is .note.module.sig a keyword or a file name? If it
is a file name, does it come with the driver rpm? Is new_module.ko a new name
for the mudule?
Adding Drivers to the Genesis Boot Kernel
The xCAT genesis boot kernel/initrd has most of the necessary IBM drivers built
into it. If you need to add a driver for another type of hardware, you can put
the driver on the xCAT MN and rebuild genesis with using the
mknb<http://xcat.sourceforge.net/man8/mknb.8.html> command. Here is an example
of adding the Adaptec AACRAID
driver<https://www.adaptec.com/en-us/speed/raid/aac/linux/aacraid_linux_rpms_v1_2_1-40300_tgz.htm>
to genesis:
* Download the tar file and extract the rpm:
tar -zxvf aacraid_linux_rpms_v1.2.1-40300.tgz
* Extract aacraid_prebuilt.tgz from the rpm:
rpm2cpio aacraid-1.2.1-40300.rpm | cpio -id '*aacraid_prebuilt.tgz'
* List the contents of that tar file and extract the file that matches your
arch, distro, and kernel version:
tar -ztvf aacraid_prebuilt.tgz
tar -zxvf aacraid_prebuilt.tgz aacraid-2.6.32-358.el6.x86_64-x86_64
* Use modinfo to verify it is a kernel module and rename it:
modinfo aacraid-2.6.32-358.el6.x86_64-x86_64
mv aacraid-2.6.32-358.el6.x86_64-x86_64 aacraid.ko
* Make the appropriate sub-directory in the genesis file system and move
the kernel module there:
mkdir -p
/opt/xcat/share/xcat/netboot/genesis/x86_64/fs/lib/modules/2.6.32-431.el6.x86_64/kernel/drivers/scsi/aacraid
mv aacraid.ko
/opt/xcat/share/xcat/netboot/genesis/x86_64/fs/lib/modules/2.6.32-431.el6.x86_64/kernel/drivers/scsi/aacraid
* Rebuild the module dependency file in the genesis file system:
depmod -b /opt/xcat/share/xcat/netboot/genesis/x86_64/fs 2.6.32-431.el6.x86_64
* Rebuild genesis:
mknb x86_64
* Genesis is now ready to use for discovery. To use the new genesis for
firmware updates or running other utilities on nodes, run nodeset for the nodes
again.
*
Thanks,
Ling

________________________________
Adding a module to the genesis kernel, as outlined here:
https://sourceforge.net/p/xcat/wiki/XCAT_iDataPlex_Advanced_Setup/#adding-drivers-to-the-genesis-boot-kernel
Can result in the following error:
"module signed with unknown key"
Could a note be added to the wiki to use "objcopy -R .note.module.sig module.ko
new_module.ko" as a means to bypass this error?
