I have the exact same problem as this guy with storage pools / virtualdisks in server 2012 R2. I can neither find a solution or referance to this warning message.

In the health screen of the properties on the Physical drive it shows Health status: Warning and Operational status: Split.
The other drive shows Health status: Healthy and Operational Status: OK.
I can't find any reference to a Operational status: Split.
Does anyone know what the "split" status indicates and how or if it can be corrected?
