Hi ,
We are stuck in problem with our private cloud protection , when ever DPM trying to backup virtual machines the cluster shared volume i.o timeout and the disk disappeared for a moment and that cause my virtual machine rebooted unexpectedly and move to different nodes of cluster .
Follow are the configuration of my Infrastructure .
1. Windows server 2012 Cluster X 6 nodes
2. DPM 2012 SP1
Event Generated when backup initiate :
Cluster Shared Volume 'Volume2' ('CSV 7TB Cluster Disk Production') 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.
I have applied hot fix as Microsoft recommended
http://support.microsoft.com/kb/2813630/en-us
Disabled ODX as well , because my storage doesn't support this feature .
please help me out to resolve this matter .
Best Regards,
Muzammil Ubaray
