  • If this occurs during RTFI, accept the message Ignore errors and continue (ALT-F8 to display, ALT-F7 to return) (Yes,No)
  • Finish the RTFI and add the node to the cluster, but do not add any drives
  • Cluster UI should show a node fault similar to:
    • NVRAM device problems detected, metadata drive will be removed. Contact NetApp Support. error={derivedCapacitanceOfThePack: 0.000 F, timeToChargeCapacitors: 42949664 Seconds}
