Good afternoon,

I have an additional disk which is attached to the VM, however every time the server is rebooted the disk shows up in device manager but is disabled "due to group policy" I can then click enable and the disk comes on line.

I am told there is a group policy key I can change to make this happen automatically - does anyone know what this is and how to set it?

  • 1. What OSes are the host and VM running? 2. Is the "server" the host or the VM? – Chris S Jun 3 '14 at 13:32
  • server = VM =window-server-2012, its hosted on openstack – GreyCloud Jun 3 '14 at 13:35
  • How does the VM think the disk is attached? – Chris S Jun 3 '14 at 13:54
  • shows up in device manager as a Redhat VertIO SCSI disk – GreyCloud Jun 3 '14 at 14:22

Open an elevated command prompt, run diskpart. From there, run

san policy=OnlineAll
