No - that's not true... Linux doesn't care about 3390 model numbers -- it takes the cylinders it's given and is happy.
The reason that I would define Mod27's as 30050 cylinders (actually 30049) Is so that 3 3390-9 size minidisks (10016 cylinders) will fit perfectly. (so: 3x10016 = 30048 + 1 for cylinder 0 ) That's the only plausible reason I see for picking that particular number... Scott On Wed, Feb 10, 2010 at 9:51 AM, Martin, Terry R.
