Answer

  • Preventive replacement is not recommended for an E-Series drive that only reports intermittent controller-side timeouts.
  • Replace a drive proactively only when an impending drive failure is detected and recorded in the Major Event Log (MEL), including: 
    • Event 2285 - Impending drive failure detected by drive
    • Event 101f - Summary of impending drive failure detected by controller
    • Event 1023 - Drive copy triggered by controller-detected impending drive failure
  • If none of these events are present and no additional symptoms are observed, preventive replacement is not required.
  • E-Series automatically manages drive copy and failure handling when a valid drive failure condition is detected.
  • Updating the drive firmware is recommended to improve stability and timeout recovery behavior.
  • If preventive replacement is required for operational or business reasons, contact NetApp Support to review available options.
