Environment

• EDR: (formerly CB Response) Server/Cluster: All supported versions

Cause

Data is present in the directory(s) indicated in the error above causing initialization to fail, data locations and error codes can differ from example

Resolution

CAUTION: Using the new installation procedure on an existing server will likely result in loss of all data, including the configuration and event data collected from sensors. Server Cluster Management Guide Page 22

1. Empty the contents of the directories indicated in the error message 
2. Run initialization process per Server Cluster Management Guide Page 22

Additional Information

• Running 'cbinit' will reset a node that has been in production back to factory settings resulting in possible data and configuration settings being lost
• Ensure a complete backup has been performed before removing data and re-initializing the server/cluster node according to the Server/Cluster Management Guide Page 40
