I don't do this on FreeBSD, but I do a lot of this under HP/UX. Our configurations look like this: --------------- --------- ---------------- | Host Adaptor0| | DISKS | | Host Adaptor1 | | SCSI ID=7 |======| |=======| SCSI ID=6 | | | | | | | --------------- --------- ----------------- As for termination, remember that SCSI is a bus. It goes from here to there, and has a terminator at each end. We no longer use the on card termination. HP make a nifty pass-through terminator (part number C2980A, for F/W/D busses only) that allows one controller be disconnected without breaking bus termination. Very handy if you need to do work on one system without disturbing the application running on the other. I advise against putting a SCSI controller in the middle, unless you use a Y cable.
