Hi.
I have a Hyper-V Server 2012 with a single VM for Server 2012 R2. I gave that VM access to two 1TB disks as physical disks, and had Server 2012 R2 add those disks to a storage pool. That configuration worked for awhile, and then I added a third 1TB disk to the system. When I rebooted the Hyper-V Server, the physical disk mappings in the VM were lost. On the Hyper-V Server, diskpart reports the two older drives as online. I can only get diskpart to change the status of the new drive, and naturally only get the new drive to show up as a option to use as the physical disks in the VM.
Diskpart reports the older drives as online, 0 bytes free, and there's only an '*' in the Gpt column. When I ask to make those disks online, diskpart reports success; but the status never changes. Rescan doesn't make a difference, they always show up as online. I've tried making them online, and diskpart reports they are already online. I've also tried booting the VM without these drives; but the status is the same.
I could live without the content of these drives; but I'm not sure nuking them will ever allow them to be made offline again. So, I'd rather try to persist the data for awhile.
Thanks for any help.
