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:

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:
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.

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

Device 2: enabled, ID 3, device Hard Drive, start sector 18636800, sector size 512,

<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:

T-ERR-SCSI A - id = 4 lun = 0

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