Subject: [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

DISK

         MODE SENSE :                        1A0003001C00

         MODE SENSE :                        1A0004001800

         FORMAT :                            00000000 040500000100

         FORMAT WITH DEFECTS :               00000000 041D00000100 00C00000

         READ CAPACITY :                     25000000000000000000

         DISK INFO :                         FFFFFFFF 00000003 0000 0000

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

different.



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 ?

I'm not a SCSI expert, but as I'm trying to get a 3B2/1000 (very similar)
going from bare metal (dead drive) I've run into the same SCSI problems trying
to get a non-AT&T small drive to work. Somewhere out there is an idtools (I
think I found it on
Yahozna, just need to write out a quad-density disk of it) that supposedly
gives you
much more control over the SCSI formatting process than the included AT&T
files.

AT&T SysVr3 should be pretty much bog-standard SysV FS, which can be read on
Linux with the proper
module/driver.
