[Marco_Galbiati]

I try backup a many VMs on 3 nodes hyper-v failover cluster. Severl VMs fail with following message error:

AOFO: Initialization failure on: ... Advanced Open File Option used: Microsoft Volume Shadow Copy Service (VSS). Snapshot provider error (0x1398): The cluster node is not the owner of the group.
 

Backup Exec version is 2010 R2, Windows 2008 R2.

Someone can help me?

Thought I'd get back here as we corrected the issue. It was Microsoft related, we had to install a MS hotfix for this to work. Regards, G
