[rescue] 3B2 / SysVr3 disks on Sun ?

I really don't know where else to turn. Someone here may have an idea.
I have a 3B2/600 I want to use modern scsi drives on. I can ID them and
assign them to devices but, it can't format them. I suspect it doesn't
know how to deal with drives over 1gb or something similar.
I was wondering if there was a way to build one on a Solaris box then
move it to the 3B2. It would seem like the 3B2 should be about as
standard SysVr3 as there is. I haven't tried it but, I've heard you can
even see 3B2 disks and partitions on Solaris. Just not interact with
them. Is there a sysVr3 disk standard and can Solaris access it ? Linux ?
In the ancient past third parties sold drives >1gb for the 3B2. They
modified three files to do so. Two I can handle and have. The third is
way beyond me. I know its dealing with SCSI commands but, how to change
it isn't clear. Here's is the default scsi version that doesn't format
my disks so far:
# cat sd00.0
MODE SENSE : 1A0003001C00
MODE SENSE : 1A0004001800
FORMAT : 00000000 040500000100
FORMAT WITH DEFECTS : 00000000 041D00000100 00C00000
READ CAPACITY : 25000000000000000000
DISK INFO : FFFFFFFF 00000003 0000 0000
VERIFY : 2F000000000000000000
READ DEFECT DATA : 37001D00000000000000
I am sure the formatting will be all screwed up but, I tried. It should
give you an idea. I am guessing these are commands sent by the format
program to the drive. These newer scsi 2 drives probably need something
For once google has failed me on a problem. Just not enough 3B2 info out
there. I've spent hours looking through the old news group archive even.
Nothing. I think the whole trick is making a custom version of the above
file but, I have no clue how. I see these commands listed in drive
documentation like but, I don't see how it relates to those. There a
SCSI expert out there that can decipher this ?
