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

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?

This means you can allocate up to three volumes, but only one is in use,
now.

It means what it says.
You can't get there from here.

PS: Not to nit-pick, but it's software, not hardware.
