Several years ago I allocated various sized disks to my personal zLinux machine, formatted, partitioned, and mkfs'd them as ext3 filesystems. I unmounted them and CMSDDR'd them to CMS files in an "EMPTYEXT3" SFS directory (they compress really nice - just over 100 cyls to store a 10016-cyl ext3 filesystem). Now, when I get a request for a, say 3338-cyl ext3 0X0202 disk, I allocate the minidisk, CMSDDR RESTORE the appriorate-sized preformatted backup, run ICKDSF CPVOL LABEL VOLID(0X0202), and give it to the zLinux box, all ready to go.

One idea would be to create a tool similar to SWAPGEN that clips cyl 0 of a
minidisk from CMS to provide a label that Linux can recognize, incorporate
that into the DIRMAINT format minidisk exit (insert your product equivalent
here), and thus stop the whining at boot. You could then partition,
dasdfmt, and mkfs as normal, but still avoid the messages about
unrecognized disk.
