As Jim mentioned it's the 512 to 520 byte sector mapping. The only time this is a real issue is for the load source which MUST be 35GB or larger or you cannot install to it.

If you want the math it's 1.0729. That is take the size you want and multiply by 1.0729 and that's the size to use on CRTNWSSTG (rounded up of course!) For those of you who may be wondering it's the same number to use for Storwize SAN disks. Multiply what you want IBM i to see by 1.0729 and use that number when creating SAN disks.

Check my math with your disks and you got 1.072858 or 'REAL close'. :-)
