  • ONTAP 9
  • Data ONTAP 8.2 7-Mode
  • CLTFLT:HA Group Notification from node  (CONTROLLER TAKEOVER COMPLETE AUTOMATIC) ALERT

Event Summary

This message occurs when an automatic takeover of the partner is successful.

  • When a node takes over its partner, it continues to serve and update data in the partner’s aggregates and volumes. HA availability overview

By default, takeovers occur automatically in any of the following situations:

  • A software or system failure occurs on a node that leads to a panic. The HA pair controllers automatically fail over to their partner node.

    • After the partner has recovered from the panic and booted up, the node automatically performs a giveback, returning the partner to normal operation.

  • A system failure occurs on a node, and the node cannot reboot. For example, when a node fails because of a power loss, HA pair controllers automatically fail over to their partner node and serve data from the surviving storage controller.
