Thanks Robert and others,
We figured there would be a learning curve, I think we'll get it figured
out, we just need to figure out everything, then how you do those things
on SLES12.

Without NPIV you're in that same boat.
Even if you had NPIV you would still have to mount the new clone and fix
the ramdisk so that it points to the new target device instead of the
golden image.
This is especially an issue for DS8000 type storage units that give every
LUN a unique LUN number based on which internal LCU its on and the order it
gets created. Storwize devices like SVC and V7000 do it differently: each
LUN is numbered starting from 0000 and counts up from there for each host,
so the boot LUN is always LUN 0x0000000000000000 for every clone and you
don't have to worry about that part so much.
The gist of your issue is that you need to:
mount the new clone volume on a running Linux instance
chroot into it so that your commands are 'inside' that cloned linux
environment
fix the udev rules to point to the correct lun number
fix the grub kernel parameter to point to the correct lun if needed
fix the /etc/fstab records to point to the new lun if needed
?? re-generate the initrd so that it does not contain references to the
master image ??
( I'm not sure whether that last one is required on SLES 12 )

Completely agree with you .. I might make an exception if the only

use is for z/VM to supply EDEVICEs
AND the PCHID is configured in the IOCDS as non-shared.
