To create a volume, use the Create command. The arguments the Create command accepts vary depending on what is being created. In the case of the example, the first argument is the key word volume that specifies what is being created. The second argument is the object being made into a volume, in this case lvm/Sample Container/Sample Region. The third argument, compatibility, indicates that this is a compatibility volume and should be named as such.
