Both problems are because the drives in question are plugged into an mpt(4)
controller, not the mps(4) controller in the system.

The first one is because mpt(4) controllers only support up to 3Gb of
course, but the second one is because mpt(4) controllers don't support
SATA drives over 2TB.  Or more precisely don't let you access the capacity
over 2TB.

Both problems should go away if you plug them into the mps(4) controller.
