This isn't important.

It's always better to make a backup, and there's always the danger
that something will go wrong when you rebuild hardware, but basically
this is what you need to do:
1. Put the disks in the system, anywhere.
2. Start the system.
3. Start Vinum.
Your data should be found automatically. It's a good idea to do an
fsck -n on the data to make sure it's OK. Make sure you use the -n
option; if you do find a way to confuse Vinum, it will be very
confused, and you don't want to write anything back to the volume
until you're sure Vinum knows what it's doing.
