The command I am issuing is a simple "mt -f /dev/st0 rewind"
1) The unit does not give a vendor id, yet /proc/scsi/scsi shows
some. It actually shows the info from the lower id.
2) Any attempt to access the tape gives a scsi error. I need to
know if this is a real drive problem of is the driver failing
to talk to this unit which seems to have a strange scsi
implementation.
3) After the bus reset, why is id=0 being reset when the error was
on id=2?
