So, you’re onto your last node of a 10.2.0.1 CRS install and you see this message…
Running vipca(silent) for configuring nodeapps
The given interface(s), “nxge0” is not public. Public interfaces should be used to configure virtual IPs.
This is can be caused by your public network interface being 10.x.x.x – vipca assumes that this is a private network.
Login as root and run vipca from $CRS_HOME/bin – this will allow you to set the interface types correctly.
