Examine the cluster configuration ASCII file , sometimes
called /etc/cmcluster/cmclconfig.ascii or better create a new config file using current settings using cmgetconf command. You might have some 
STATIONARY_IP exists, change it to HEARTBEAT_IP  and cmcheckconf and cmapplyconf.

or

if you have extra interface, create entry below each hosts as:

NETWORK_INTERFACE lanx
HEARTBEAT_IP xx.xx.xx.xx

and check and apply the config.
