I have a box with 6 drives. 2 x 350 GB , as RAID 1 and 4 x 1.2TB as RAID 6. The OS (Server 2012) was installed on the Raid 1 and the Raid 6 was reserved for for virtual machines. After studying Hyper-V basics, I found that storage pools may be a more efficient way to proceed than the original Raid 6 I had prepared. However, I also read that to setup a storage pool, any existing volumes and Raid arrays needed to first be deleted.

Following the elimination of the volume on the Raid 6, the storage pool manager was able to see the available disks. I set out to use a mirrored and/or stripped pools and get an error message saying there was not enough disk space. The only option I was able to use was "Simple." I then went to the Raid controller and eliminated the Raid 6 array. Following that, the storage pool manager was unable to see the available disks.


My question is how do I turn the Raid controller off on the four drives and use HBA? Is this even possible? Why was the pool working (simple) when the disks, according to the Raid controller, were setup as Raid 6, but without a volume on the drive(s)?

I like the idea of Raid simply because of eventual failure of drive(s). However, the storage pool seems cool not only because of failed drive replacement (which I can't get to work), but because the pool(s) actually show up on the host OS...
