First query the cluster:
cmquerycl -C clu.conf -c

Adapt the cluster conf file
NODE_NAME

Apply the cluster conf file
cmapplyconf

Distribute to all nodes

Forgot to mention that in cluster script
only lanx is nominated.

In the ascii package control.sh script you
find the package ip@ for your package (change manually)
e.g.

IP[0]="10.214.16.153"
SUBNET[0]="10.214.0.0"

The process should be :
1)Get the current cluster config file by cmgetconf keep a copy of it.
2) Halt the cluster and keep autostart option of cluster off in /etc/rc.config.d/cmcluster
3)Change the hostname and IP address of the cluster node by set_parms
4)Reboot both the server
5)Either chnage the current cluster acsii file or recreate it by cmquerycl
6)Finally check and apply cluster config

Hi,
The sequence will be for example
cmgetconf -C /tmp/cluster.ascii
modify the cluster.ascii file with the new IP
cmcheckconf -C /tmp/cluster.ascii
cmhaltcl
cmapplyconf -v -C /tmp/cluster.ascii
cmruncl
mv the conf file on /etc/cmcluster
