I believe thats' the function were are all waiting for.....

check to see how many deleted blocks, or what the space saving would be if we run the UNMAP command.

I've seen many scripts, which are run across datastores, relcaimining storage, but to date, I've not seen a script, which can display, how much would be reclaimed before the script (unmap) is executed.
