Agreed. If you have a large MASDEF and you try to list volume stats from a different system, it can take quite a while for the info to come back. Suggestion is shared checkpoint volumes be at 100 at all times, or gen the checkpoint volume to just the systems that use it. for MASDEF=99999999. Page add a temp volume, Page delete one old volume, replace it on new dasd, repeat for next volume, FDRPAS / TDMF / EMC z/OS Migrator all work great, move volumes during normal work hours. IPL over the weekend on new volumes. TDMF had a whole list of what products / datasets had to be closed for the swap. Follow religiously or you get unexpected hangs.
