DEC was were specific about the settings for SCSI mode that MicroVAX
3100 firmware and VAX/VMS would accept before enabling third party
drives in that era. Not all early drives that would accurately
do/report media recovery operations.
Suggest you look at this post and compare to the SCSI drive settings.
Its a bit of work, but I have updated the mode settings for drives used
on my MicroVAX's. I cannot speak for the DEC2000.

Nigel,
If you have two drives of the same volume name in VMS that will cause
issues. You did not provide a lot of detail to give you specific answers.
Its complex but here is a starting point

I am a hobbyist in vms, not an expert.

I am trying to format a couple of SCSI drives on the Alpha. They are
connected using the external cable and are mounted in an Open Storage
Systems (OSS) box. The drives were working when removed from a PC.
SRM shows only one of them coming up as DKA200. I have set the two
drive ID switches to 2 and 3.
Lack of info is hampering me, I have gleaned form various sources that
the following command should work:
t scsi format a 2 0
which just returns
OK
immediately, without doing anything.
VMS allows me to ini the disk, but then when I try to mount it, I get an
operator services message saying it is offline, please mount volume in

Anybody with experience here?
cheers,
