If the volume shows a star (*) then it is a place holder only. Takes up no room or space. Just lets you know that if you need to go beyond one volume you can.
Check out candidate volume in the SMS manuals. There is no SPACE to release when there is a * for the volser So rather than specifying a volser to start with, SMS just puts in a place holder. Only space you can release is allocated space Think of the IDCAMS statement DEF NVSAM(NAME(xxx.yy) VOL (* * * * *)) This define could go on 5 volumes. But does not have to. Until the allocation uses a * no space is actually allocated Lizette -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Charles Mills Sent: Friday, June 07, 2013 4:15 PM To: [email protected] Subject: Re: Multiple volume dataset question Well, everything is software these days. Cylinders exist only in software any more. So if a dataset is *eligible* to span more than one volume, you can't release unused space? Even though the dataset has never occupied more than one volume? What if it is allocated with // DD SPACE(,,RLSE) and closed by a program? Will the excess space be released?

You can't get there from here.
