If I understand correctly disklabel -e ad3 auto will create you partitions
without creating slices. You should get /dev/ad3c and this will cover the
entire disk (though I don't know if this is really supported). Normally
you should put slices onto your disk and disklabel the slices. Given that
you have a correct fdisk label you should have the slice entries
/dev/ad3s[1-4]. Then you can disklabel the slices: 'disklabel -e
/dev/ad3s1 auto'. ad3s1c of course does not exist if you don't have
labeled the slice. You must label the slice (da3s1), not a partition
thereof (da3s1c).
