For starters, 50 lashes with a wet noodle for not being clearer in the
statement of question. What I failed to make clear was that, following the
install of the miniroot on the drive I could not boot the miniroot.
So the pointers to making sure I ran installboot, while appreciated, were
not applicable.

After spending time on the phone with Sun it was determined that the drive
itself was the problem, I could boot a 4/330 with this drive but not the
630. After contacting the vendor, I found that the drive was ~8 revs out of
date (GB-15 vs JB-22!) they shipped me a replacement and all is well.

The thing that tipped us off was when a probe-scsi command was issued
the drive responded for all 8 LUN positions (virtual disk? :) )

So, rumors to the contrary, you can boot a 630 and 670 from SCSI,
but make sure that if you have a MAXTOR P-12S, it has a rev near
