Which multihoming method is that?

I am just getting started with RHCS, from Sun Cluster. I was planning to use private node host names as the primary cluster communication, using an ethernet bond of two NICs. I was also planning to have Luci available, until I am more adept at knowing what to add to cluster.conf by hand. Does Luci not function when the primary cluster communication is over a private node interconnect?


Thanks,

Ivan.
