Trucluster creation

I have only installed Tru64 clusters on new systems before but am unsure
of the consquences of creating a cluster from current a production
system.

We are in the process of creating a SAN and adding the Tru64 environment
to the SAN, which opens up the possibility of creating more clusters.

If I create a cluster from a working 5.1A or 5.1B system will I lose the
AdvFS files and application data? To lose a production environment for a
long time would be a big problem, there would be too much data to
restore. 

I would like to create a single node cluster from the current system and
then add another node
