Resolution

  1. Any BBU failure must first be evaluated to ensure the current controller code is running before replacement.​​​​​ The system must be running 08.40.60.01 or greater.
  2. If the controller firmware is not current as listed above, the firmware must be updated first.
  3. After the firmware is updated, a new manual learn cycle must be run - How to manually start a battery learn cycle using SANtricity
    1. On rare occasions, this may need to be run twice to fully recover a battery affected by previous downrev code issues.
  4. If none of above solved the issue, please contact NetApp Technical Support as a replacement may be necessary.
