I had an issue sometime back where I was running validations on my Server 2008 R2 (RTM) Hyper-V cluster with an EMC Fibre Channel SAN. While running validations, one of my CSV LUNs came back with a damaged MBR and all data was seemingly lost. A call into Microsoft got the MBR restored, and all was fine, but I was down for the majority of a day.
My question is simply, was this a fluke experience, or is there a proper procedure for validating a Hyper-V cluster. I am now running SP1 on all nodes, and I am preparing to join another node to my cluster. I would like to perform all validation tests before I proceed.
