I believe the current DASD driver will get it right:
dd if=/dev/dasda of=/dev/dasdb
where if you copy the whole disk you'll get a working bootstrap.
But this requires that the disk was formatted with 'dasdfmt'
ahead of time. More accurately, it requires that the target was
formatted with the same layout as the source.
Adam's point is important. ZIPL is not only "traditional"
but is the only way to be sure you have a bootstrap on the target disk
that has been put in the right place (from what ZIPL can determine).
The CDL layout in particular does "funny things" (my term) with track 0.
