John,

When I try to  'mount' the volume again to load the requested tape I get the 
following error: "3001 OK mount requested. Specified slot ignored. 
Device="Drive1" (/dev/nst0)". Then I get several messages in the console asking 
me to 'mount' the volume I just mounted (located in slot 12, volume 51L4). Here 
are the commands I'm issuing. 

Thanks,
JJ

Maybe its my description but its confusing..

BTW, the ramifications of using the unmount command is that you have to issue 
mount to get bacula to use the tape drive again. However  if you use the 
release command bacula does not require you to mount.
