Just a note here, when looking at the above.  What is significant is that all 
the values are zero, which means that the tape is expected to be on that 
device but is not currently in use.  What is incorrect is that two different 
volumes are listed with the same drive -- unless it is currently in the 
process of mounting (acquiring) one, in which case, the non-used one will be 
released when the new one is fully mounted ...  at least in theory.
