Answer

  • When an equivalent EMS event indicating the condition has passed occurs, and is sent from ONTAP to UM, the event is marked as Obsolete
  • Example:
    • wafl.vol.autoSize.fail event is received, raising an event to indicate an attempt to autosize a volume per policy failed.
    • Later, after the condition is attended to, a write is attempted to the volume, causing it to try to autosize again, which now succeeds.
    • This generates the wafl.vol.autoSize.done event, showing that autosizes now work on the volume, and the event is marked obsolete by UM.
