Well, looks like I didn't do enough work on my own before firing this
posting out to the list. After looking around on the web a bit more, I think
I found the answers to my questions (I think).

The first issue, with the fibrechannel adapter on one machine using a
"scsi@" device was due to (for some reason) the adapter itself. Swapping
that out with another adapter resulted in the correct "ifp@" device. As far
as I'm aware, they're the same model number, etc, but...

For the second issue, it seems that I need to mess with /etc/path_to_inst a
bit. A couple of articles which helped were:
