Well if the same setup works on other machines of the same type, except
that one, I would suspect that there is a problem with hardware. My
personal experience with Sun hardware is actually quite bad, so i I
avoid them at all costs.

Deleting partitions doesn't delete anything on the disk - it just
'deletes' contents of MBR. Once you set up partitions, lvm/md will
detect existing lvm/md partitions and show them. You should delete
logical and raid volumes before creating new ones.
