ERROR: Could not find a suitable set of interfaces for VIPs. July 6th, 2009 . by admin

You install Oracle RAC and use CVU to check the environment, for example before Cluster install. runclufy.sh complains always:

ERROR:
Could not find a suitable set of interfaces for VIPs.

and all people on the Net say: ..is ok, can be safely ignored. But why?  

Here is the understandable statement from :

CVU checks for the following criteria before considering a set of interfaces for VIP:
– the interfaces should have the same name across nodes
– they should belong to the same subnet
– they should have the same netmask
– they should be on public (and routable) network.
Oftentimes, the interfaces planned for VIPs are configured on 10.*, 172.16.*, ..or 192.168.* networks, which are not routable. Hence CVU does not consider them as suitable for VIPs. If none of the available interfaces sastify this criteria, CVU complains "ERROR: Could not find a suitable set of interfaces for VIPs." It is worth noting that, such addresses wil actually work if they’re public but CVU thinks they’re private and reports accordingly.
