You can only have one scratch pool at a time.  So if you change your
existing scratch pool's properties and uncheck the "scratch pool" box,
then create a new scratch pool, your LTO4 media will go to the new
scratch pool (because of the Barcode rule) and your old LTO3 media go to
the old scratch pool and not get used. Another note on the barcode
rules, you can create a <DEFAULT> barcode rule (put "<DEFAULT>" in the
barcode box when creating the rule) to create one rule that applies to
all media that get loaded, regardless of barcode.

Or create new LTO4 Pools that contain only LTO4 media, then when the
LTO3 expires back to their pools, these will no longer be used by the
Policies. Thus enforcing only LTO4 media is used. Yeah? All the
information I've been getting is making sense now.

Thanks everyone.
