   My recent experience in trying to install a Quantum Atlas 4, 9 Gig
which ships running SCSI 3 is that it won't work out of the box in a
Sparc 20.  I installed it into a Sparc 20 then booted on the Sun
CD-Rom...  Instaled Solaris which seemed to recognize the drive and
partitioned and functionality as I expected...  like normal but when I
tried to boot it up the monitor prompt failed to recognize the drive.
It spun up but probe-scsi failed to identify the drive.  It listed the
ID but the drive did not ID.  An e-mail to  Quantum and some searches
resulted in a DOS utility to switch / force the drive to the older
SCSI 2.  They also indicated that the LATEST version of the drive bios
would auto switch...  but I forced it with the Dos utility and a PC
with a SCSI interface.  

Once I forced it to SCSI 2 It now ID's with Probe-scis and boots...
Real nice an QUIET, Fast for a 7200 rpm drive...  2 Meg Cache...  this
drive makes this old Sparc 20 with a Dual SM51 feel responsive
again...  at least a nice X Terminal...
