I don't think you can do what you want to do because the linux partition table won't see the extra cylinders. Nothing jumps off the page on the s390tools site. I think you are stuck with defining a bigger minidisk and copying the data over. LVM's are easy to extend and that is what I use for almost all my filesystems.
