Abstract
Approaches to using a backup heartbeat interface to detect and mitigate high availability (HA) split-brain conditions are described. Heartbeat packets from the primary appliance received via a regular heartbeat interface of the backup appliance and monitored the backup appliance to determine whether the connection with the primary appliance via the regular heartbeat interface is stable. A backup heartbeat interface on the backup appliance is enabled in response to a determination that the primary appliance is not operating properly resulting from analyzing at least a status of the heartbeat packets from the primary appliance. A backup heartbeat packet is transmitted from the backup appliance to at least the regular heartbeat interface of the primary appliance in response to a determination that the primary appliance is not operating properly. Services are provided with the backup appliance to replace services previously provided by the primary appliance. Transmission of the backup heartbeat packets from the backup appliance continues while providing services with the backup appliance.
