    I'm just guessing about this but I'll bet that they can or will be
soon. This would increase the market for the SCSI based disks and make
it easier to sell them. I know that the DN2500 uses controller numbers
like 5 & 6 for its SCSI disks. On a Dn3500 with the WD controller If
you try to use unit numbers like these, you'll get:

1) Under sr10.1

$ mtvol w5:0 1 /garp
?(mtvol) The controller number specification is incorrect; legal values are '0' through '3'.
         Help is available.

2) Under sr10.2

$ mtvol w5:0 1 /garp
?(mtvol) Unable to mount volume - controller not found (OS/I/O manager)

So it looks like either it'll already work under sr10.2 or the're planning
for it.
