It has NOTHING to do with the software. The problem happens to anything,
even CPIO.

No. The tape drive hangs the bus. It happens to Adaptec, NCR, Conner.

SCSI bus locks up from time to time. My solution is to get a new TAPE.
Once a tape is having a messed up block it starts to lock the SCSI bus.
4mm DDS is quite painful. The tapes drive needs to be cleaned up every
32 hours of use (em, 8 hours of backup and 8 hours of verify, PER server) so
that means I have to clean it every 2 days. With about 12 servers you can
tell how much fun that is.
The 8mm Exabyte is WAY more reliable, but it's too expensive.
I wonder having 2 seperate SCSI controller will be a better idea, since the
tape drive lockup (when the HD is sharing the SCSI card) can cause a panic.
