Configuration

A virtual machine is configured with a SCSI controller that cannot be used because the guest operating system does not support SCSI controllers.

Virtual machines cannot use storage attached to the SCSI controller. This impacts the following virtual machines:<list of virtual machines>

Shut down the virtual machine and use Hyper-V Manager to remove the SCSI controller from the virtual machine. Then, restart the virtual machine.

By default, membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure. However, an administrator can use Authorization Manager to modify the authorization policy so that a user or group of users can complete this procedure. For more information, see Using Authorization Manager for Hyper-V Security (http://go.microsoft.com/fwlink/?LinkId=142886).

  1. Open Hyper-V Manager. Click Start, point to Administrative Tools, and then click Hyper-V Manager.

  2. In the results pane, under Virtual Machines, select the virtual machine that you want to configure.

  3. In the Action pane, under the virtual machine name, click Settings.

  4. In the left pane of the Settings dialog box, under Hardware, click SCSI Controller.

  5. In the right pane, click Remove Controller.
