I notice on the ouptput from 'q dasd details' the "CYL =" value, that it is present even if the disk is FBA (VFB-512 attached to CP running second level, or EDEV attached to second level, or even first level EDEV (on the "SAN connected" system). But fixed block do not have cylinders that can be used by CP or CMS.
I guess the question is: what factor is used to calculate this number? I might have expected dividing the size by 720K to fudge 3390 cylinders, but it looks closer to maybe 360K. What's the story? -- R; <><
