It looks like after adding the additional DASD volume to the file system with "btrfs device add" the proper incantation is "grub2-install". After that, rebooting the system works just fine. Just make sure you use YaST, or the dasd_configure command to bring the new DASD volumes online initially. Simply using "chccwdev -e" won't cause the udev rule(s) to be written, nor will it update /boot/zipl/active_devices.txt.
