I have a Windows 2008 R2 Hyper-V Cluster that has 3 nodes. I am seeing the CelerraVSSProvider event ID 1 being generated when we are trying to do backups. We are using Microsoft DPM to perform backups and the Celerra VSS Provider is installed.

Here is the error code we are getting

 

Error. SnapApiIntf::getDevAttrEx() : -> SnapApi failure: (0x490) SysErr:Element not found.

(hr: 0x8004230f) VSS_E_UNEXPECTED_PROVIDER_ERROR
