I was either sacrifice a data drive to make it a backup of the primary or

I’ve got a DEC 3000/300 system that has some SCSI drives with aging
bearings installed. I’d like to be able to start to migrate some of my
systems, like this, to flash media, of some kind, as even my large
repository of SCSI disks is starting to dry up.
Here is my SRM level info:
   DEC 3000 - M300
Digital Equipment Corporation

As far as I have read, the SCSI2SD v6 2020 should be compatible with
several varieties of DEC hardware, from the VAXen to the Alphas. However, I
can’t seem to get anywhere useful with mine. I have the virtual disks
configured as follows:
sh dev
BOOTDEV      ADDR      DEVTYPE    NUMBYTES     RM/FX    WP    DEVNAM
  REV
-------      ----      -------    --------     -----    --    ------
  ---
ESA0         08-00-2B-3F-4C-9A , TENBT
DKA100       A/1/0     DISK         9.54GB      FX            RZ40
   6.0
DKA300       A/3/0     DISK         9.54GB      FX            RZ40
   6.0
DKA400       A/4/0     RODISK     305.01MB      RM      WP    RRD45
    6.0
All three disks are from the SCSI2SD. I have attempted to make the
inquiry strings match the originals, as closely as possible. In the SCSI2SD
utility, I have the following config:
General page: all defaults, termination off (I have tried parity, scsi2
mode, and setting SCSI speed to sync, with no improvement)
Device 1: enabled, ID 1, device Hard Drive, start sector 0, sector size
512, sector count 18636800, vendor “DEC     ", product “RZ40     “,
revision “ 6.0”, serial number <random string>
Device 2: enabled, ID 3, device Hard Drive, start sector 18636800,
sector size 512, sector count 18636800, vendor “DEC     ", product “RZ40
“, revision “ 6.0”, serial number <random string + 1>
Device 3: enabled, ID 4, device CDROM, start sector 37273600, sector
size 2048, sector count 148933, vendor “DEC     ", product “RRD45    “,
revision “ 6.0”, serial number <random string + 2>
I’ve also tried booting from a virtual CDROM, only, with no luck there,
either. In all cases, I get the following from SRM:
test scsi
T-STS-SCSI A - Data Trans test
? T-ERR-SCSI A - Data Trans test - nondma/sync inq size miscompare
T-ERR-SCSI A - id = 1 lun = 0

? T-ERR-SCSI A - Data Trans test - nondma/sync inq size miscompare
T-ERR-SCSI A - id = 3 lun = 0

? T-ERR-SCSI A - Data Trans test - nondma/sync inq size miscompare
T-ERR-SCSI A - id = 4 lun = 0
?? 002      SCSI 0x0008


84 FAIL

Does anyone have an idea what might be causing this? Has anyone tried a
v6 SCSI2SD in a DEC 3000?
Thanks!

I picked up a couple v6 boards for my AlphaStation 200 4/233, but haven’t
tried to use them yet.

Are you using the onboard SCSI, or a SCSI board?  I’m ‘going to assume
you’ve tried a different cable, and to get it working from actual physical
drives?  Have you tried turning the termination on, on the board?  Is your
SCSI Bus Terminated?

You actually have RZ40’s in the system?  I’m asking as I’m not actually
familiar with that drive type, at least it’s not one I remember off the top
fo my head.  I usually use RZ29’s.  On my v5.2 board on my VAXstation
4000/90 I think I went with basic 8GB drives, without a vendor string or
product string.
I have a Quantum XP2160 and a Seagate 1050 in my 3000. Both function, but have 
significant bearing whine, and I have no idea how many hours are on each. So, I 
know my scsi subsystem and termination are fine. I’m going to pull a scsi2sd 
v5.2 from a Quadra 700 and try that, to see if I get the same errors.

I used the RZ40 as the inquiry string, and matched the sector count, to make 
SRM happy. I have real RZ25s and RZ26es, but they are quite small. Most of my 
modern scsi disks are 10 and 15k U320s, and not a good choice for heat 
constrained enclosures like the 3000. Not to mention that 300gb is just silly 
for Digital UNIX.

Difference in length of data sent or expected for SCSI-1 vs SCSI-2 inq 
commands?
