Hello Alan,

 From what I have heard many times, "tapeinfo" can do a scsi clear 
command (at least in some cases). Until that is disproven, I cannot 
consider adding it to mtx-changer as a scsi clear is rather catastrophic 
to an autohanger in a multi-tasking, multi-processing environment.

Best regards,
Kern
