Re: DASD cylinders
That use of orthogonal is common in computer science. Axes at right ang les (orthogonal) are used to represent independent variables. These variables can be manipulat ed independently. So in this sense orthogonal and independent are similar. But in computer sc ience they talk about orthogonal design, rather then independent design, because the latter could mean many other things. I'm with Alan, and not just because he spells his name right!

Sir Alan probably had the thumb at the wrong spot in the dictionary. Maybe he meant independent or not defined by instead. Working with mini disks we have learned not to expect the model number to define the number of cylinders, and we probably rarely have to. IMHO it's an omission that the number of cylinders of the disk is not in the monitor data. Rob -- Rob van der Heij Velocity Software, Inc http://velocitysoftware.com/ = == ==

Re: DASD cylinders
How then do I have actual volumes on my system of 32,760 cyls. That's not divisible by 1113 (ds8000 here). Marcy: Sorry, I was not clear. Allocation is in multiples of 1113 cylinders. You can make a volume whatever size you want, but if it is not a multiple of 1113 cylinders, the remainder up to the next 1113 cylinder boundary is not usable. Therefore, if you defined a volume of 100 cylinders, you would be wasting 1013 cylinders. Jim

Re: DASD cylinders
There may not be a physical 3390 Mod 27. As newer DASD hardware has been created, and with the need for larger and larger disks, the new hardware emulates the 3390 in larger and larger sizes. We regularly use 3390 mod 27 DASD, with 32,760 cylinders on each device. These are emulated on portions of disks with 9 inch platters. We¹re talking about going to 3390 mod 54, and I¹ve seen messages talking about 3390 mod 81. These are not ³just variable sized 3390 mod 9¹s². And your storage folks are correct, none of these devices ever really existed. But then, how many shops have any actual 3390 devices left at all? Ours have been emulated for many years. EMC, Hitachi, IBM Shark, IBM DS8000... They all ³do² 3390, in varying sizes and with newer features than a 3390 ever thought of. (Snapshot copy, mirroring, ...) I see that the $DASD$ CONSTS S file shows a 3390-9 as having 65,520 cylinders, but such a beast never lived that I know of. We¹ve just been honoring the 3390 all these years by trying to do things they would have done them.

Re: DASD cylinders
32760 on a mod 27. The 27 is to a 9 as the 9 is to a 3. :) Not really. 3339 * 3 = 10017. 10017 * 3 = 30051 and 30051 32760. I think it was ICKDSF support when I reported a strange message that said they were really all 9's, just of different sizes Which kind of goes along with what $DASD$ CONSTS seems to suggest. IBM?

Re: DASD cylinders
Right, there's the details query.
