When using Cloud Edge HA groups, you should understand under what conditions an HA group failover occurs, which include the following:
  • One or more of the monitor interfaces are down
  • Heartbeat or ping takeover thresholds reached
  • Active gateway does firmware update
  • Replacing an active gateway
  • Force takeover
    If the HA group is in an abnormal state, force takeover will not happen.
    When force takeover is triggered, the primary will become standby and the secondary will become active.
