That would be the "Prefer Mounted Volumes" option.  I find this much 
simpler than creating a multitude of different pools.  I also prefer to 
use one policy for data retention--it's never seemed very useful to me 
to keep incrementals for a shorter period of time than full backups as 
the incrementals generally take up so much less space anyway.

I have had a situation where a tape drive needed cleaning.  That 
resulted in something like 10 tapes being marked in error when first 
used.  The moral is to keep your drives clean.  Auto-cleaning detection 
has never been helpful for me and cleaner style tape leaders are not 
sufficient from my experience with LTO-1 and LTO-2 drives from both IBM 
and HP and a variety of different tapes.  If the actual drive died in a 
"permanent" fashion like a tape breaking or a power failure then the 
drive will be blocked and other jobs should continue onto the remaining 
tape drives.  Anything currently writing to that drive will fail but if 
you're using spooling that should be just one job.
