Greetings Mark, I finally am able to successfully reboot the system.
I will try to test to see what actually worked.

Never use the base device for anything. Always use a partition.

If this is a z/VM system, you should disable cio_ignore entirely. Either
way, for a SLES12 (not SP1 and not SP2) system, when you add another device
to the root file system, you will need to manually re-run grub2-install.
Also, make sure that you used dasd_configure or YaST to bring the DASD
volume online. Those are the two ways to make it come online across
reboots.
