I have a brand-new 2012 R2 VM (Gen 1) on a 2012 Hyper-V host that is in SCVMM 2012 R2. Upon adding four pass-through GPT disks via Failover Cluster Manager, the VM is now "Unsupported VM Configuration", error 659, saying there is already a device at SCSI 0,0. A Refresh doesn't change it, and a Repair is not applicable.
I researched that multiple GPT disks were not supported in VMM 2008, but I assume they are OK now in 2012 R2. I looked over the VM's settings in Failover Cluster Manager and SCVMM, and there is no conflict of SCSI port/LUN. There seems to be nothing wrong with the VM itself, but SCVMM is giving a false alarm, I think. What could be causing this?
