I am working with Dell on hardware related issue on a cluster node and we have narrowed the fix down to replacing the motherboard. However I don't want to just go ahead and replace the motherboard and believe everything is going to work afterwards. For starters i know assigning the same static IPs to the new NICs will simply not work till all references to the old NICs is removed from the registry. Secondly I have no idea what other impact this will have on the cluster config.
Given the uncertainty I am inclined towards evicting the node from the 3 node Hyper-v cluster, incur some downtime for some of the VMs due to reduced capacity, change cluster config and then replace the motherboard. Since this sounds like a lot more work than a simple replacement I am looking for any alternate suggestions or validation for my plan.
OS is Server 2008 R2 fully patched and storage is iSCSI
Appreciate any feedback.
