Well I have rules for different things.

My catalog tapes have custom barcodes (makes them easy to spot or find)
So I have a rule to put those in to the catalog pool
I have some other special barcode labels as well with special pools.

I also have more than one location and more than one master.
All normal tapes for each location start with a different letter..
So I create barcode rules that if a tape from another location comes in, it 
also goes to a special pool so it does not go to the scratch pool.

You can have different pools for different media types.

In your case you need to keep your two types separate.
Which should be done with media type like hcart, hcart1, hcart2, hcart3

But if you are not doing that you would have to play with barcode rules and the 
instructions of where tapes go when them come back into a library.

(taken from tech doc 303076)
With the RETURN_UNASSIGNED_MEDIA_TO_SCRATCH_POOL set to yes, then these things 
are true:

Any tape media that started out in the scratch pool before it was assigned will 
go back into the scratch pool once the images have expired and the tape has 
been unassigned. 
If a tape media was assigned to a pool without ever being in the scratch pool, 
then that tape will not go into scratch once it has been expired and 
unassigned. It will remain in its originating volume pool.
---------

So if your bp.conf has this and set to yes, and you put all your new tapes into 
the scratch pool they will go back there when they go unassigned.

You have to look at what you need and see how the options will allow you to get 
the end result.
Now if you are going to get rid of the lto3 tapes, then just don't put those 
back into the library.

That tiny bit of information just answered tons of questions. Thank you!

So now I know how to properly handle all new incoming LTO4 tapes. And
ensure they wind up in the LTO4 scratch pool. In order to ensure LTO3s
wind up in a "dead pool" for old tapes, do I simply enter "L3" as the
barcode rule? And when are these rules actually processed? I know it's
used when injecting new tapes, but what other situations does it apply
these rules?
