OK, thanks. I probably made the mistake of not removing first before doing work on the server.
I reinstalled because this was the machine that had a dead CPU so I had to move the NIC to a new PCI slot serviced by Socket 1 on the motherboard. This meant the interface names changed and it was easier to reinstall than spend a day working out how to try and modify the node configuration. Cheers.
