I thought about this question. The answer is maybe in my opinion.
how do you know P001 contains all the data what 0214, 0215, and 0216 need?
Unless there is a way to compare the data inside these tapes. When P001 is
mounted it will reclaim some data or maybe all tapes..

Another question I have is, during reclamation if P001 is not available,
does it grab the tape from COPY pool?
