Hi Ramesh,

Not sure if you have already received any info from Steve.

You need to use mcastaddr and mcastport values in the openais.conf file.
The nodes having these values same will form a single cluster. So if you
want to form 2 separate cluster, just provide the set of nodes with 2
different values of these parameters.

Regards,
Shridhar
