How to re-map ethernet devices.

Subject:

If an ethernet device happens to get remapped to a new name at the OS layer you will need to rediscover the device to re-build the device mapping.

Or if you're installing QuantaStor from a template you may also need to re-build the ethernet device mapping

 

Details:

If the original ethernet device was "eth2" and is now showing "eth4".

In a case like this you will need to remove the "/etc/udev/rules.d/70-persistent-net.rules" file and reboot the system to recreate it.

 

This file associates your NIC's MAC address with an interface name that will be given to the NIC at startup.

To make the change, rename the file '/etc/udev/rules.d/70-persistent-net.rules' to '/etc/udev/rules.d/70-persistent-net.rules.bak', then reboot and watch the behavior to see if the issue is resolved.
