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.
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.
