What is supposed to happen if a SCSI disk has a power glitch and then returns
Unit Attention? I would think that the operation should eventually be retried,
but I seem to be seeing all further normal access to that device hang, even
though scsiinfo is still able to talk to the device just fine. How about if a
driver sends a Bus Device Reset to the disk device? I'm trying to resolve some
reported problems with error recovery in my new BusLogic driver, but it seems
the problems might not be driver level at all. Comments?
