Frank, According to the manual (and another post) VSAM extends with the Primary allocation. Assuming that I misunderstood and you plan to re-allocate with 9980 as your Primary allocation, let me ask - Why would you use a Primary allocation that is so large that it effectively excludes most if not all of the volumes in your storage group? My advice to you is to make your Primary Secondary smaller more reasonable values.
Get a copy of VSAM De-Mystified from IBM Redbooks. Much of what you think you know about VSAM is false. Don't take that personally, it applies to almost everybody including me.

And that the IDCAMS input, I thought was the current and correct input, can not be correct. We will follow your adwise. Just a thought - if we were to add a new (empty) 3390-9 to the storagegroup we would have a secornd allocation go there with 9980 cyls allocated?
