The Linux disk driver probes to determine if there is a valid IBM standard label on any disk device it sees; if not, it falls back to assuming the disk is a CDL formatted disk (a bad assumption IMHO, but then I'd like to see CDL completely go away so we don't have to explain this weirdness to people). All those messages are telling you is that that probe process didn't find a IBM standard label. They're normal for unformatted disks. To get rid of them, you need to format and partition the new disks with fdisk and dasdfmt. Adding the MDISK statement is equivalent to plugging in a brand new blank drive; you still have to format the drive for use with the operating system. If you want to do that outside the Linux environment, use LXFMT (http://www.sinenomine.net/products/vm/lxfmt).
