Try this part of the man page:

     vinum drives are currently BSD disk partitions.  They must be of type
     vinum in order to avoid overwriting data used for other purposes.  Use
     disklabel -e to edit a partition type definition.  The following display
     shows a typical partition layout as shown by disklabel(8):

     8 partitions:
     #        size   offset    fstype   [fsize bsize bps/cpg]
       a:    81920   344064    4.2BSD        0     0     0   # (Cyl.  240*- 297*)
       b:   262144    81920      swap                        # (Cyl.   57*- 240*)
       c:  4226725        0    unused        0     0         # (Cyl.    0 - 2955*)
       e:    81920        0    4.2BSD        0     0     0   # (Cyl.    0 - 57*)
       f:  1900000   425984    4.2BSD        0     0     0   # (Cyl.  297*- 1626*)
       g:  1900741  2325984     vinum        0     0     0   # (Cyl. 1626*- 2955*)

     In this example, partition ``g'' may be used as a vinum partition.  Par-
     titions ``a'', ``e'' and ``f'' may be used as UFS file systems or ccd
     partitions.  Partition ``b'' is a swap partition, and partition ``c''
     represents the whole disk and should not be used for any other purpose.

     The vinum utility uses the first 265 sectors on each partition for con-
     figuration information, so the maximum size of a subdisk is 265 sectors
     smaller than the drive.

No.  It requires a partition type 'vinum'
