control-link-recovery

Syntax

Description

Enable control link recovery to be done automatically by the system.

If the control link fails, the secondary node enters to ineligible and then to disabled state. If the control link recovers with in three consecutive responses, the device auto reboots irrespective of the state (ineligible or disable) of the node. You can reboot automatically using the control-link-recovery configuration option.

After the control link recovers, the system checks whether it receives at least three consecutive heartbeats on the control link. This is to ensure that the control link is not flapping and is perfectly healthy. Once this criterion is met, the system issues an automatic reboot on the node that was disabled when the control link failed. When the disabled node reboots, the node rejoins the cluster. There is no need for any manual intervention.
