Troubleshooting

The validate_tra_config.py script returns status messages to the console where it is run. The INFO messages it returns are for your information. The WARN messages indicate possible issues with the TRA configuration that might need fixing.

This WARN message indicates that the VIPs are not the same between the two TRA nodes of an HA pair: 
WARN: VIP configuration appears to be mismatching between nodes - please refer 
to deployment documentation for more information

Each VIP defined in the tra_config_network_topology.xml file has if-name, address, and netmask entries that are normally the same. The if-names entries can be different, but if they are different, that spawns the WARN message. You can ignore this message if the if-names are different because:

  • You run a MATRIXX implementation in a cloud environment such as Google Cloud Platform. Cloud platforms typically do not allow VIPs, so you must set the real IP address of the TRA servers. The real IP addresses are different for the two TRA nodes, causing this message.
  • You use the Red Hat 7 interfaces that are generated. In this case, the interfaces might have different names but reference the same thing.
