If you can't do what Alan said, you can do ddr from z/vm or dd in linux which have access to both - old and new storage (the old linux should be down during the clone process)
There are good chances that it will ipl fine from new storage. As Mark mentioned, it might depend how did you set it in fstab. But good chances are that you use one of these in fstab: /dev/dasdnx (asking for troubles) /dev/disk/by-path (I think most common for non-lvms?) /dev/mapper/xxxx (if LVM used) My bet is that you have disk-by-path or/and /dev/mapper/. If that's the case, no changes to fstab should be needed. It should ipl without a problem. When I think about it, disk/by-uuid should also work. Correct me if I am wrong, but it's just an id of partition which will be cloned with all the data. If you use FCP then it's different and longer story.
