LM UNLOAD LMan:

 	This command will unload the specified file from the LM device. This
 	is different from LM DISCONNECT in that the unit will be kept available
 	for subsequent reuse with the LM LOAD command.

1    /LOG

  /LOG
  /NOLOG (default)

 	Shows the status after the device has been unloaded.

2    /TRUNCATE

 	This qualifier will truncate the container file to the highest written
 	block. This can be used to trim excess blocks which may be left over
 	from an extend operation.
