My guess would be that the truth is, the externally-visible switch on
the enclosure is set to 5 (or 4), but the enclosure's wiring between
that switch and the disk is not connected, so the disk proper naturally
enough responds as target 0.

Depending on the drive, the wiring, and your comfort level with such
things, one option might be to open the enclosure and connect that
wiring - or, if the connectors are mechanically incompatible, add
jumpers (probably on the drive) to set whatever ID you want.

Or, as kre says,

	sd0 at scsibus0 target 3

or, alternatively,

	config netbsd root on sd1a type ?

(Actually, I'd probably use "config netbsd root on *a type ?", but I
think that syntax was one of my additions, one which I don't recall
seeing any reason to think NetBSD picked up.)

As another option, you could move / to the external drive, but that of
course has its own downsides.

Well, not the only way, but that could work too.
