Alan, The problem that Jason is having is that his extended forat datasets will not extend to a new volume once the initial allocation and extents are full, or there is no more space on the original volume. As I recall, this is the behaviour for DSOR=PS striped datasets whether you allocate your stripes using data rate or Gurenteed Space.
For "(SYSDA,59)" to have an affect he must use gurenteed space, otherwise allocation will use the data rate in the STORCLAS. Gurenteed Space for stripes also means you get 59 allocations of your Primary Space requested, so it needs to be reviewed. Data Rate divides the Primary Space by the number of stripes.
