SPACE=(CYL,(500,500)

nbollineni,
After you use the 3390 chart in the link above to calculate recs per cyl remember that errors can occur if you're not able to allocate secondary space. An option is to use more than one unit. Code JCL as UNIT=(unitname,2) to use two units, for example. SMS routines may also be affecting the actual allocation and units used.

With no space restriction, you'd get primary plus 15 secondary allocations.
