And if you switch to GB, a storage group with one Mod 9 shows up as 7 GB in z/OS 1.13. The DCollect records are calculated by the Track size in bytes * number of tracks, divided by 1024, and stored. To determine the number of cylinders from this size, I add 1 and divide by a slightly smaller size. Otherwise the Mod 29's are off by a cylinder. I wish they would truncate at the bytes in a cylinder, so that every volume size is an exact multiple of that number.
