Both work for me  :-)

Here's mine.  AHA-3940 as secondary controller, on-board NCR PCI SCSI as
primary controller:

controller      ncr0
controller      ahc0
controller      ahc1    at isa? bio irq ? vector ahcintr


controller      scbus0  at ncr0

disk  sd0 at scbus0     target 0 unit 0
disk  sd1 at scbus0     target 1 unit 0
disk  sd2 at scbus0     target 2 unit 0
disk  sd3 at scbus0     target 3 unit 0
disk  sd4 at scbus0     target 4 unit 0
disk  sd5 at scbus0     target 5 unit 0
disk  sd6 at scbus0     target 6 unit 0

controller      scbus1  at ahc0

disk sd10 at scbus1     target 0 unit 0
disk sd11 at scbus1     target 1 unit 0
disk sd12 at scbus1     target 2 unit 0
disk sd13 at scbus1     target 3 unit 0
disk sd14 at scbus1     target 4 unit 0
disk sd15 at scbus1     target 5 unit 0
disk sd16 at scbus1     target 6 unit 0

controller      scbus2  at ahc1

disk sd20 at scbus2     target 0 unit 0
disk sd21 at scbus2     target 1 unit 0
disk sd22 at scbus2     target 2 unit 0
disk sd23 at scbus2     target 3 unit 0
disk sd24 at scbus2     target 4 unit 0
disk sd25 at scbus2     target 5 unit 0
disk sd26 at scbus2     target 6 unit 0

Ok ok ok so I got disks on the brain.

Anyways.  Note that I use "octal" type notation to make locating drives
easier, "sd23" is unit 3 on bus 2...  it certainly is not REQUIRED you name
your devices in this fashion however!!  Very arbitrary on my part.

This box flies by the way  ;-)
