Symptom
I clicked
Discover
 in Command Center and received an error that automatic Discovery cannot be completed.
Reasons
Discovery can fail for the following reasons:
  • A component is not running and cannot be detected
  • All components do not have identical SSH credentials
  • One or more components are running on Windows (use Manual Discovery in this case)
Solution
Discovery can fail for different reasons.
Follow these steps:
  1. Rerun automatic Discovery. Discovery can fail because a component cannot be detected.
  2. If Discovery fails again, select the cluster from the
    Name
    drop-down list in the
    Server
    tab of Command Center.
  3. Click individual components to learn more details about the component.
  4. Review any components that show an error in the UI.
  5. Download the log file in the
    Application Logs
    section.
  6. Review the server upgrade errors.
  7. Review the Controller logs, and search for error entries that provide information about what component or server failed.
  8. Select the Discovery instance, and click 
    Delete
     to delete the discovery data.
  9. Click 
    Refresh Existing Data
     to rerun Discovery.
