I hope you don't have it set to 60% all the time. But actually change it
from 100 down to 60 when *you* want it to happen!

And are you referring to onsite-Tapepool or offsite-Copypool?
I manage mine entirely differently. :-)

I set onsite-Tapepool to the next available (highest) tape rec number
using a perl program.

I set offsite-Copypool to a rec number that is comfortable with a complex
formula that floats in my head.  rec=highest 15 to 20 eligible tapes if I
have enough scratches to cover it where scratches = scratches-5 for DB
backups, etc, etc.  Which usually turns out to be 18,19,20 or 21.
