Following on from some very speedy replies (big thanks to Steven for his 
direct responses and allowing me access to his document repository), I may 
have been rather hasty in my purchase of drives for the SPARCstation 20s.

After some additional searching with different terms, I came across the 
following message thread:

From: Thomas Anders (anders@hmi.de)
Subject: IBM LVD drive in Sun SS20/U1?
Newsgroups: comp.sys.sun.hardware, comp.periphs.scsi
Date: 1999/11/17
http://groups.google.co.uk/groups?hl=en&lr=&threadm=0r903x2or8.fsf%40hmi.de&rnum=6&pre \
v=/groups%3Fq%3Dsparcstation%2B20%2B18GB%26hl%3Den%26lr%3D%26selm%3D0r903x2or8.fsf%2540hmi.de%26rnum%3D6


The above describes my issue exactly, as my drives do not show up with 
"probe-scsi" or "probe-scsi-all" either. I still find it rather odd that the 
OpenBSD installer is able to find the drives!!!
I believe from further research that the Single Ended mode on this 
particular drive is not having any effect (I have tried jumper-setting the 
Forced Single Ended Mode on the drive). I have tried two identical drives (I 
bought three of them) in two different SS20s.

It would appear that that this problem is not related to OpenBSD but with 
Sun OBP & SCSI weirdness.

It would seem that I will need to replace the cable assemblies (and do some 
case modifications) too in order to get these drives working. It may be 
cheaper to re-sell these LVD drives and purchase alternative drives instead. 
If someone can recommend 9GB or 18GB SCA drives which *definitely* work with 
SS20s, please let me know.

TIA.

Nick =(
