Before trying to fix (if required) the packs of your new VM system, use ICKDSK CPVOL FORMAT on a spare pack and see if FDR likes that better. Because, I'd think that when the z/VM 5.3 disks were created at IBM, the same ICKDSF was being used. I also suppose that the process to create the INSTDVD DVD has simply physically read these install packs and stored them as binary files on some server that burned a DVD. A z/VM on tape would be similar, but here DDR would have been used to create a physical copy.
As for emailing a DDR TYPE of a cylinder 0: sorry, I'm at home now, no VM here. 2008/1/18, Schuh, Richard <[EMAIL PROTECTED]>: > Way back when IBM first started putting dummy VTOCs on devices used by > VM and ACP, I pointed out that relying on a Format 5 DSCB that said > there was no space was not the correct way to do it.
