When Microsoft Hyper-V Server is started, it automatically tries to mount all the volumes that are connected to the server. These volumes include volumes on local disks and Storage Area Network (SAN) logical unit numbers (LUNs).
The default SAN policy in Microsoft Hyper-V Server is designed for ease of use. The policy enables the user to get started with a deployment immediately, without having to mount additional volumes that are stored on a SAN. However, you may not want to use this default setting in some environments.
To resolve this problem use one of the following methods to change the default SAN policy.
Method 1: Use diskpart
Method 2: Set the SAN policy in the Unattended setup file for automated deployment scenariosThe following code will change the SAN policy not to automatically mount SAN hosted volumes.
