Changing IP in Cluster Nodes

 We are having two node cluster in M9000 Server. In which the network setup needs to changed now i.e. IP address of the nodss and the cluster IPs are to be changed.

Current /etc/hosts files are as follows

Node-1

root@WFMS1 # cat /etc/hosts

#

# Internet host table

#

::1     localhost

127.0.0.1       localhost

10.22.43.8      WFMS1   loghost

10.22.43.9      WFMS2

10.22.43.12     WFMS1-nxge0-test

10.22.43.13     WFMS1-nxge4-test

10.22.43.10     WFMS_DB

10.22.43.11     WFMS_APPLN

==================================

Node-2

root@WFMS2 # cat /etc/hosts

#

# Internet host table

#

::1     localhost

127.0.0.1       localhost

10.22.43.9      WFMS2   loghost

10.22.43.8      WFMS1

10.22.43.14     WFMS2-nxge0-test

10.22.43.15     WFMS2-nxge4-test

10.22.43.10     WFMS_DB

10.22.43.11     WFMS_APPLN

==================================

Whereas WFMS_DB & WFMS_APPLN are resource groups and it's cluster IP's are respectively 10.22.43.10 & 10.22.43.11
