Depending on how many LPARs have the dataset LLAed you can have a LOT of work to get that space reclaimed. (Note: rambling anecdote follows. ) In my previous shop I had a loadlib of a non-IBM product in the linklist. Maintenance of this product was separate from our standard mantenance procedures. Once maintenance had been applied and tested in its target libraries I would bring the product down on all LPARs, copy from target libraries into "run time" libraries, compress them, do an LLA UPDATE on all LPARs, and restart the product. I got tired of having the loadlib overallocated to handle the copy so I switched to a PDSE with just a little extra space. All was fine until I had maintenance to apply. I was able to copy 4 out of a couple hundred modules before the library filled. Out of panic I decided to delete all modules from the library and tried again. :-( Very bad decission! I knew of no way of seeing who had the library open but after seeing 12 ENQUEUEs on it, I gave up. A few minutes later I was back on a PDS.
