Sorry to require remedial instructions... it works now. The trick was my misunderstanding that the tunefs.lustre needed to be run on the MGS given the mdt.
I've rerun tunefs on the new OSS for all the OST's w/ the original settings, and. likewise on the MGS for the MDT, with all original settings, and the multi-mome works again. Thanks to all that pitched in on this. Sorry I was so dense.
