The pvcreate command only creates LVM2 labels, it does not update the
MBR or other disk label at all.

That's your job ;)
If you chose to use partitions for PVs then you need to create those
partitions and set their type codes appropriately (although LVM2
doesn't actually check/use those type codes anywhere - it's really
more of a "documentation" step these days).

None of them. If you use the whole disk as a PV it should not have any
MBR at all.

Bryn.
