Hard Disk Emulation fails due to SAN Policy conflict

Across various machines running Windows 8 and above, I have come across an issue where I can only mount a volume or disk under basic emulation or, at most, flagged as a removable drive. However, if I flag the drive for Hard Disk Emulation (Slower) and attempt to mount the drive, regardless of an image being used or a clean slate, an error occurs and the disk does not mount, and an error code is presented on my screen. What I have discovered while watching the mounting process through Windows 10 is a SAN Policy conflict: when mounting begins, the disk remains in an offline state.

My solution, which I have now done to all of my machines and has resolved the issue:

  • Run an elevated command and load into DISKPART
  • Change the SAN policy by typing the following: SAN POLICY=OnlineAll
    Nothing else, just mount the disk.
