Hi
Since a few days i got the following error when i try to back up VMs with DPM 2010.
"Triggering synchronization on \Backup Using Child Partition Snapshot\servername failed:
Error 30148: DPM was unable to access the cluster resource group hostname.domain for \Backup Using Child Partition Snapshot\servername of protection group abcde
Recommended action: Verify that the cluster resource group hostname.domain is accessible by using the Cluster Administration console."
The Protection Group protects seven VMs. Four of them fail with the error mentioned above, the other three work fine. there are other protection groups which protect VMs without any problems. The failed VMs run on different CSVs and on different Hyper-V.
Some Information about our Infrastrucutre:
- two windows server 2008 r2 hyper-v, configured as a cluster (all updates installed)
- three CSVs
- one DPM 2010 running on windows server 2008 r2 (all updates installed)
can anyone help? i saw there is another topic for this error, but the answers there didn't help.
regards from switzerland
