To be more precise...I will quote from an online posting: "an extent is a contiguous area of disk space". The key word is 'contiguous'. Since an extent must be 'contiguous' you primary extent cannot span volumes. The largest extent you can allocate is equal to the largest free space on a volume. In your case a full volume, or 3336 cylinders. You won't get a second allocation until you fill up the first volume.

Hi, I am trying to allocate dataset with 6672 cylinders of space across two volumes as a primary extent. I am told that the allocation should look as shown below... //DD1 DD DSN=TEST.DATASET, // DISP=(,KEEP), // SPACE=(CYL,(3336,20)), // VOL=SER=(VOlUME1,VOLUME2) I tried above allocation but I am getting just 3336 cylinders as initial allocation. What could be wrong here? Should the volumes be non-SMS? If they are SMS does it need some SMS rule to allocate primary space specified across each of the volumes?! Please help.
