Here is a tip which will save you a headache if you are installing Clusterware on a new server.
Before you begin a new Clusterware install, make sure when you receive your servers from the UNIX admins that the VIPs are not already configured and active. However, you should have the host and IP for the Virtual IP in the domain server and local hosts file.
Do netstat -inw at a UNIX prompt to see the interfaces. You should not see the VIP interface.
If it is configured or active, you can unplumb it if it is NOT aggregated (e.g. APA):
ifconfig lan0:1 unplumb
or if it is APA:
ifconfig lan900:1 0.0.0.0
By setting the IP address to 0.0.0.0 it disables the secondary interface.
/etc/rc.config.d/netconf file has the interfaces which are started at boot up. They can be commented out to remove an interface following a reboot.
