In Microsoft Hyper-V, I have a Server 2008 R2 virtual machine that keeps losing a 2 TB virtual hard drive.
The base and virtual operating systems are both Windows Server 2008 R2. All Windows updates have been installed.
I used the Hyper-V management program to create the 2 TB virtual hard drive (which holds my SQL logs).
While the Server 2008 R2 virtual server is running within the Hyper-V environment, the 2 TB virtual hard drive suddenly disappears.
What can I do to troubleshoot or fix this issue?
