I'm trying to backup virtual machines hosted on a 4 nodes Windows Server 2008 R2 Hyper-V cluster. The cluster has two cluster shared volumes. One is on Netapp iSCSI storage, the other one on the Dell MD3200. If I try to backup machines on the MD3200 CSV they are not snapped using the hardware provider.
Looking further into this issue with vssadmin, diskshadow and a simple NTFS volume on the MD3200:

The registered provider does not support shadow copy of this volume.Not even snapping this simple volume is possible!
Dell claims it's the backup software and DPM 2010 is not supported. But at least the above test with diskshadow should work in my opinion....
I have configured the HW provider according to Dell's document "Data Protection in a Hyper-V Environment" but to no avail. Now I'm stuck, spent money on the array and the snapshot license for it and it doesn't even do the basic stuff.
