Bug Description

Here is the exception trace: http://paste.openstack.org/show/27866/

To reproduce it:

Provision DevStack or any other controller
Install Cinder Volume on a Windows Server
Create a volume on the Cinder server: cinder create 1
Wipe out the Windows server (e.g. by revertining to a previous snapshot) and reinstall Cinder Volume
When the service starts Cinder queries the status of the volumes
If the volumes are not found, you get the above error

To fix it the following WMI result length needs to be checked before taking the first element:

 wt_disk = self._conn_wmi.WT_Disk(Description=vol_name)[0]

    Fixes a Windows volume driver bug on disk export

    Fixes Bug #1089168

    When a VHD created by Cinder using the iSCSI Target Server is deleted
    manually, at the next startup the cinder-volume service terminates with an
    exception.
    This fix adds a check to verify if the disk exists.
