INS-40927 Interfaces with common subnets that have different names

Question:  How do I fix the INS-40927 error? I am getting the "INS-40927: Interfaces with common subnets have different names on different nodes." error when trying to install Oracle 11g r2 Grid control:

 

Answer: The oerr utility says this for the INS-40927 error:

INS-40927: Interfaces with common subnets have different names on different nodes.
Cause: The following nodes have interfaces in common subnets that have different interface names: string
Action: Ensure that the names of interfaces defined on common subnets are the same on all cluster member nodes

All interfaces have to use the same name. The interface (e.g. a public LAN), must have the same name on all nodes, same naming ruke for the interconnect. 

Solution:

First of all, stop all virtual machines. Goto virtual machine setting and remove network cards and add one by one in each virtual machine and startup machines.

PRVF-5410 check of common NTP Time Server failed

Do it on all cluster nodes

Either configure NTP, or make sure it is not configured so the Oracle Cluster Time Synchronization Service (ctssd) can synchronize the times of the RAC nodes. In this case we will deconfigure NTP.
