In versions of old, you could specify interfaces per cluster member. This allowed me in the past to easily overcome a faulty NIC by moving one member to a different NIC and just updating the topology for that single member. I've done it a few times and it worked a treat!
Now that option appears to have gone. I have a cluster member that has developed a faulty eth0, so I want to move that cable to the spare eth6 which is proven working. When I do this the member stays "down" because the cluster is expecting to see eth0 up.
Is there a way these days to keep eth0 on one member and eth6 on the other member, like I could in the past? Otherwise I have to schedule a downtime window to change both gateways to eth6, and go on-site to install the policy from the 'inside'... It turns a 2 minute remote job (albeit with remote hands to re-patch the cable) with no downtime into a fully blown scheduled outage with a site visit, which is a royal pain in the..... and a step backwards from what we could once do.
