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
VPP PAL V5.56-80800101/OSF PAL V1.45-80800201 - Built on 30-SEP-1996
09:18:31.84
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!
