A little more info.  The current storage size is 2,997.5 GB.  Capacity on the existing disks is 124.9 GB each, additional disks are 136.3 GB each (reported from iSeries Navigator).

I used the AS/400 term loosely.  It's a Power 720 system.  I currently have 24 126.9 GB drives protected with raid 5 and am needing add an additional 24 139 GB drives with the other drawer I mentioned earlier. 

Thanks for the response!
