Josh,
I had one more clarification.
partimage binaries run in the management node to capture an (stateless)
image from the compute node right? In that case, is there a need for
these binaries to go into the rootimg.gz??
My assumption is, partimage runs on the management node (an intel blade
in our case) to capture a stateless image from a compute node (a power 7
blade) and stores these images under " /install " of the management
node. Please correct me if I am wrong here.
Regards,
Sunil

Hi,
I used the steps that were mentioned under
https://cwiki.apache.org/confluence/display/VCL/Adding+support+for+partimag
e+and+partimage- ng+to+xCAT+2.x+%28unofficial%29
to enable partimage support for xcat. I wasn't sure if I need to change
references to x86& x86_64 (as directories) to reflect the ppc
architecture, as the web page says "The architecture for the node must
always be set to x86 for this..". I have with me the vmlinuz (kernel
image) and initrd for the capture process. The 2 nodeset commands
By this, do you mean you have vmlinuz and initrd for your power blades, not
the ones linked to off of the page you listed above? If you do, that's a good
start. However, you'll also need rootimg.gz. rootimg.gz is the root
filesystem for the stateless image. It also contains the partimage and
partimageng binaries. Assuming partimage or partimageng can actually capture
partitions from power systems, you'll need to compile at least one of them to
run on power. For the rootimg.gz image I provided, I compiled them statically
so that I didn't have to worry about including any library dependencies in
rootimg.gz.
It would be a good idea to research how to use xcat's genimage command to
generate stateless images to learn how to do this.
If there's any part of the above that you don't fully understand, please ask
me to clarify it. Until you have a stateless image that you can deploy to
your power blades, there's no point in trying to debug any VCL specific items.
