UPDATED 1/6/2014 – New hotfixes available
Some customers are experiencing failures on Windows Server 2012 Hyper-V hosts that utilize Cluster Shared Volumes (CSVs) when backing up virtual machines (VM’s) using System Center 2012 Data Protection Manager (DPM 2012) with Service Pack 1 (SP1) or later.
When this occurs the following error is logged on the Hyper-V hosts.
Log Name: System Source: Microsoft-Windows-FailoverClustering Event ID: 5120 Logged: <date/time> Details: Cluster Shared Volume 'Volume2' ('ClusterStorage Volume 2') is no longer available on this node because of 'STATUS_CLUSTER_CSV_AUTO_PAUSE_ERROR(c0130021)'. All I/O will temporarily be queued until a path to the volume is reestablished.
You may also see the VM’s pause temporarily, go in to a paused state, shut down, see memory spikes or CSV go into a failed state on the Hyper-V hosts. Configuring serialized backups doesn't help the problem.
It has been determined that any backup product using shadow copies results in the same errors, thus this isn't necessarily a DPM 2012 issue.
The Windows and DPM teams have released a series of fixes to address some general Cluster, CSV backup and DPM issues and are now available for download.

Any idea when the final hotfix will be released? It's been quite some time now.
C'mon MSFT it's been like three months
also using lun and host serialization on dpm side will minimize the impact of error 5120/5142
Is this fixed? I see there is an update, but the TechNet forums look like folks are still experiencing issues.
I'm glad to see that R2 is coming out, but maybe instead some effort can be put into fixing this once and for all?
sad that there is nothing but SILENCE about this
Some of the confusion may stem from the fact that this is affected by a few different things, so the update in the post may fix things in one scenario but not for another. On a positive note, there is a new update that should make things work much more seamlessly.
KB2848344 - Update improves cluster resiliency in Windows Server 2012 (support.microsoft.com/.../2848344)
Note that this replaces KB2838669 mentioned in the post above. If you continue to see problems protecting Windows Server 2012 Hyper-V guests after installing this hotfix please open a support case for further investigation.
Installed both Hotfixes (KB2838669 & KB2848344) but still having the issue. This is ridiculous. How could Microsoft's own products not work together properly.
We still have this issue...on 2012 cluster and using dpm 2012 R2 and have the rollup hotfix KB2870270 installed.
This has been a problem on 2008 R2 cluster as-well, we have never been able to do host level backup's on the Microsoft clusters....
Good day. The contribution to the community is great, and I read the publication arose a question. The company has a Storage IBM V3700. Currently scdpm want to install a VM with Windows server 2012 presenting an HBA to the VM. I could confirm whether this
is possible or that you should consider. Thanks
