NVP-vProxy: NetWorker reports 'vProxy VM Not Found for Instance UUID'
Summary: The NetWorker VMware Protection (NVP) vProxy appliance is used to protect the vSphere environment. The NetWorker server logs repeated errors indicating the vProxy VM cannot be found by its instance Universally Unique Identifier (UUID). The vProxy was migrated to a new vCenter server which assigned a new UUID that no longer matches the registered certificate. ...

Symptoms
The Backup Administrator migrates a vProxy VM to a new vCenter server. The NetWorker server /nsr/logs/daemon.raw shows repeated error messages every few seconds:
MM/DD/YYYY HH:MM:SS [NETWORKER_SERVER_NAME] nsrd NSR error vProxy '[VPROXY_NAME]' VM not found for instance UUID '50154b1e-4727-a71a-20a6-90b793ffe33d'.
The VM backups running on the reported vProxy still complete successfully. The error does not prevent backup operations but generates continuous log noise.
Cause
VMware vCenter assigns a UUID to every VM at creation. The vProxy was deployed on the original vCenter and registered with NetWorker using that UUID. When the vProxy migrates to a new vCenter, the new vCenter assigns a different UUID. The registered UUID in NetWorker no longer matches the vProxy VM. The vProxy certificate is tied to the original UUID, and a mismatch causes NetWorker to report the VM is not found.
Resolution
The vProxy must be re-registered against the new vCenter server to generate a new certificate.
The steps to re-register are documented in the "Unregistering and re-registering a vProxy after removal" section of the Dell NetWorker VMware Integration guide and in article: NVP vProxy: How To Unregister/Re-Register a vProxy Appliance?
