Applies to

  • NetApp Console Classification  1.45.0 and above

  • On-premises NETAPP Console Agent (all supported versions)

Issue

After migrating or reattaching an existing NETAPP Console Classification (DataSense) VM to a new Agent, the following symptoms are observed:

The Classification dashboard in Agent fails to load, showing “Something went wrong” errors and  UI also reports “Agent waiting to initialize.”
All containers appear to be running, but functionality is impaired.
Log output from the DataSense VM and containers includes:

Elasticsearch container logs show the main index (e.g., directories-v47) in a red/unhealthy state.
