   There are no "SCSI ports meant for hard disks" on a Sun.  It is/was 
common, and was supported, to put CD-ROM drives, tape drives, and other 
stuff on those SCSI interfaces.

   Most Sun stuff expects a CD-ROM drive to be at target address 6, 
though this is not a hard requirement.  The CD-ROM drive does need to be 
set up for 512-byte blocks, though.  Later OBP firmware can issues a 
command to switch from the default 2048-byte block size to 512 bytes, 
but not earlier releases, prior to (I think) OBP 3.0.
