Robert,
We had some problems similar.  Make sure the P7K is
configured the same from both the front panel
AND from the Prism Web interface.  In the Web interface,
go to Libray Management-Library Configuration.
Your settins should be:

Online on Power Up    YES
No Barcodes           NO
Auto Load             YES
Auto Drive Unload     NO
Auto Clean            YES
Auto Inventory        YES
Temperature Detection YES 


The Auto Drive Unload is the one that was
causing us problems unloading the tapes.

Also, try testing using the /usr/openv/volmgr/bin/robtest
command to load and unload tapes....Be carefull!

Hope this helps.

John
