Hyper-V – Fixing Broken Volume GUIDs

Yesterday I had an interesting problem I had to fix. As you may or may not know, using Hyper-V within Failover Clustering sometimes requires the use of volume GUIDs for storage if you have more LUNs than drive letters available (like we do). What you may not know is that these GUIDs can, under some circumstances, change – completely screwing up Failover Clustering’s ability to move virtual machines between nodes.
