You ever been an MVS person ? Used partitioned data sets ? ? ? OK, TSM will do a trick where it bundles a lot of little files in a big file within ~TSM space~.
OH, look at it like a ZIP file so if a bunch of little files are in this one big file that TSM is dealing with, natrually some files will expire before others... RECONSTRUCT will do just that to these AGGREGATE (like zip) files and purge out the expired data when it moves it during reclamation (or during move data now I see...) ie, it reconstructs it without the old/expired data Dwight E.

This is similar to move data, with reconstruct=yes, but is more automated. Just set reclaimstg to your new storage pool, and reclaim down to 1. You may have to do a few move datas at the end, to get the tapes that are 0% reclaimable.
