OK I'll give it a try. I have a vinum RAID 1 running though, but the 
way to get it tunning isn't very different.

c: is not a valid disk label. You need to create one first. See the 
example below first: there's an "e" label.
You can do this in sysinstall: Configure / Label / ad4 and then C to 
create one.
Once that's done it'll show up in disklabel as you write below.
Then in disklabel you can change the 4.2BSD to vinum.

Of course you can also add the whole label-line in disklabel itself but 
I find sysinstall easier.
