I suspect preallocate is going to be the answer until DSS supports it. The reason I say this is from the RECLAIMCA doc: You may use data set RESTORE to upgrade your non CA Reclaim enabled data sets to CA Reclaim enabled data sets. To do this, simply preallocate a CA Reclaim enabled data set. That was from https://www-304.ibm.com/support/docview.wss?uid=isg1OA28939 Incidentally, it doesn't appear that FDR has anything either.
