change IP's Addresses of cluster servers.

I followed these steps when I had change IP Address of my cluster servers.

Before you change the IP Address of your Server you must have all new ip's
when you want to go ahead.(of course..:-))
ex. Server ip and package ip.

Take backup of these directory and files

1./etc/cmcluster
2./etc/hosts
3./etc/rc.config.d/netconf

modify these files
1./etc/hosts # modify ipaddress
2./etc/rc.config.d/netconf # modify ipaddress and subnet
3./etc/cmcluster/cluster.conf # modify HEARTBEAT_IP

4./etc/cmcluster/packge/cipackage.conf # change SUBNET XX.XX.XX.XX
5./etc/cmcluster/packge/dbpackage.conf # change SUBNET XX.XX.XX.XX

6./etc/cmcluster/packge/cipackage.cntl # change IP[0]=XX.XX.XX.XX
change SUBNET[0]=XX.XX.XX.XX

7./etc/cmcluster/packge/cipackage.cntl # change IP[0]=XX.XX.XX.XX
change SUBNET[0]=XX.XX.XX.XX

8.rcp cluster.conf into /etc/cmcluster
rcp cluster.conf into other node same location

9.rcp these conf,cntl and config file into /etc/cmcluster/packge/
rcp ciVRP.conf,dbVRP.conf,ciVRP.cntl,dbVRP.cntl

10. restart the net for new ip
/sbin/init.d/net stop
/sbin/inti.d/net start

check all ipaddress which we have changed and check with linkloop also

11.cmcheckconf -v -C /etc/cmcluster/cluster.conf -P cipackage.conf -P dbpackage.conf
it should come with no error then go for the next step

12.cmapplyconf -v -C /etc/cmcluster/cluster.conf -P cipackage.conf -P dbpackage.conf
