SCSI 9-Track tape under VMS..?

David, yes, long ago. If my memory serves me right (remember this?), early SCSI support was a bit picky about non-DEC devices, so maybe (worst case) this is your problem and you either need to get original hardware or a later VMS version. In general, VMS probes devices (not only SCSI) and loads all drivers for which devices are found. No SYSGEN required, and this has been true for longer than 5.2 already. You can even rerun the device detection process without rebooting: you need CMKRNL privilege, and then (on your VAX) issue a MCR SYSGEN AUTOCONFIGURE ALL. For Alphas, it is MCR SYSMAN IO AUTOCONFIGURE, and you need SYSLCK privilege, too. In either case, the device should show up as MKAn00:, where A assumes it is connected to the first or only SCSI bus in the system, and n should reflect the SCSI ID of the device. I guess you made sure that IDs are unique? Regards, Andreas David HM Spector wrote: -- Andreas Freiherr Vishay Semiconductor GmbH, Heilbronn, Germany http://www.vishay.com
