I was experimenting with Windows Server 2012 R2 ability to use a SSD drive in a storage pool for write-back cache.
The storage pool consists of one 1.5TB disk and one 120 GB SSD drive. After a server reboot the pool shows an error status with a caution symbol on the SSD drive.
In the health screen of the properties on the SSD drive it shows Health status: Warning and Operational status: Split.
The status of the 1.5tb disk 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?
