Verifying the NIC configuration

The installer verifies on all the nodes if all NICs have PERSISTENT_NAME set correctly.

If the persistent interface names are not configured correctly for the network devices, the installer displays the following messages:

PERSISTENT_NAME is not set for all the NICs. 
You need to set them manually before the next reboot.

Set the PERSISTENT_NAME for all the NICs.

Warning:

If the installer finds the network interface name to be different from the name in the configuration file, then the installer exits.
