I've noticed that processes will fill a tape and then instead of calling for 
another FILLING tape in the storage pool, it will mount
a scratch tape. I just saw this again this morning...I had a BA STG running 
from onsite tape to offsite tape. There were 4 tapes in
the offsite pool...2 filling.. 1 full..and a filling tape being written to. The 
current tape filled up and instead of mounting one
of the other 2 filling tapes, a new scratch tape was called for. And one of the 
filling tapes was only 1.4% used!

I search the TSM site and the archives, but I must not have the correct search 
words, 'cause I can't find any hits. My TSM server is
5.3.2.1 on AIX 5.3 ML2.
