I still don't understand the problem you are trying to solve.

Can you explain the network topology?

- Do you have FC storage server, switch?
- How many nodes to do you have with FC HBA?

Do you want to add nodes without FC HBA, and you want to consume
the FC storage?

Or you want to add nodes with FC HBA, but you don't have an FC switch?
