Public bug reported:

The method retrieving a free SCSI controller slot gets all the related
disk resources, checking their address using the AddressOnParent
attribute.

The issue is that this WMI object attribute is not available on the V1 virtualization namespace, for which reason this method will raise
an AttributeError in case there disks connected to the SCSI controller. For this reason, attaching a second volume will fail.

This bug affects Windows Server 2008 R2 and Windows Server 2012 when
using the V1 namespace.
