I have a 2012 Cluster with a CSV. I have the Dell Equallogic HIT v 4.5 installed on both nodes, as well as the SCDPM 2012 SP1 Agent. When I add a replica to DPM to back up one (or any) of the virtual machines on the cluster the vss writer for Hyper-V is put in a bad state and DPM gives me the following error:
The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: VssError:A function call was made when the object was in an incorrect state
for that function
(0x80042301))
The following VSS errors are logged in the Eventlog of the Cluster Node:
Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied.
. This is often caused by incorrect security settings in either the writer or requestor process.
Operation:
Gathering Writer Data
Context:
Writer Class Id: {e8132975-6f93-4464-a53e-1050253ae220}
Writer Name: System Writer
Writer Instance ID: {754c4bfd-91e7-47b5-94a2-565196237f2a}
Things I have done:
- Remove DPM SP1 Agent and reinstall on both nodes in cluster
- Remove SCVMM SP1 Agent and reinsall on both nodes in cluster
- Remove HIT and reinstall on both nodes in cluster
- Restart DPM server
- Restart both nodes in cluster
Before the DPM agent puts the Hyper-V VSS Writer into a bad state I can create SmartCopies from the HIT Auto-Snapshot Monitor software, but as soon as the VSS Writer is in a bad state ASM no longer works:

I also have two more 2-node 2012 Clusters that have the exact same software installed, butdo not exhibit this issue.
Thanks!
