Symptoms

The PowerProtect solution is used to protect the vSphere environment. After upgrading to PowerProtect 19.21, there is a significant increase in 409 messages in the PowerProtect Server vmdm.log file.

The /var/log/brs/vmdm/vmdm.log shows:

Cause

This is expected behavior. If the document already exists, the Elasticsearch returns 409 Conflict. Changes in PowerProtect 19.21 caused an increase in these types of messages.

Resolution

The issue is addressed in the PowerProtect Data Manager release 19.22.0-18. Install the latest PowerProtect Data Manager release to resolve the symptom. The newest available releases are available on the PowerProtect Data Manager Drivers & Downloads page.
