I suspect theres a deeper issue here. You dont want to be using dynamic disks, these are only designed for use when you want to crete a software raid through windows.
I have 2 windows 2012 vms under esx5.1 with sql server 2012 installed without issue.
How did you format the drive, what settings, before using it?
