To quote vinum(8):
Where to put the data
The first choice you need to make is where to put the data. You
need dedicated disk partitions for vinum. They should be
partitions, not de- vices, and they should not be partition
c. For example, good names are /dev/da0e or /dev/wd3s4a. Bad
names are /dev/da0 and /dev/da0s1, both of which represent a
device, not a partition, and /dev/wd1c, which represents a
complete disk and should be of type unused. See the example under
DRIVE LAYOUT CONSIDERATIONS above.
Previously, it shows an example:
DRIVE LAYOUT CONSIDERATIONS
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 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. Parti-
tions a, e and f may be used as UFS file systems or ccd partitions. Par-
tition b is a swap partition, and partition c represents the whole disk
and should not be used for any other purpose.

OK, what part of the text above don't you understand?
