Hi Rajram

The cluster needs to be stopped to do this.

so here is what I will do

save the cluster configuration when it is running
stop cluster
change the IP address of the server, default gateway, etc etc I will reboot the server as well
change the IP address in the cluster configuration ascii file and check and recreate the cluster.

thanks

Re: Cluster node IP changing ...

You need downtime to change IP address.

1. need to update new primary IP in /etc/rc.config.d/netconf

2. create a current configuration file using cmgetconf

3.edit the file and update new node IP in the cluster config file

4. Update new package IP in the package control file.

5.Lastly compile cluster and package.
