How can I change the MAC address for a node in ironic/neutron ?

Solution Verified - Updated -

Issue

  • Encountered hardware failure on one of our nodes recently, which ended up requiring a full system board replacement, which has led to the mac address of the provisioning NIC changing. As the server itself is still installed and configured properly, rather than completely deleting and recreating it, want to change the mac address on that nic in ironic.
  • Is it possible to change the MAC address of existing ironic node which is already deployed ?
