Issue

  • Two cores are available in this active-passive configuration running ONTAP version 9.12.1P11.
  • The passive node has a P3 Spare to its root aggregate.
    During the upgrade process, a P3 spare disk was pulled to save the core dump, even though the core had already been saved.
  • This action triggered a "low spares" condition, as the P3 disk on Node 02 became unavailable.
