Inter-Rack Redundancy Triggers
Inter-rack redundancy supports the following triggers:
CLI-based Switchover: Manual CLI commands are used to switch the roles and trigger inter-rack redundancy failover.
-
BFD Link Failover Detection: When both the BFD links between the connected rack and the leafs are down, inter-rack redundancy failover is triggered.
-
Local Rack POD Failure Detection: When threshold percentage of POD replica-sets failing is greater than the configured threshold value, the inter-rack redundancy failover is triggered.
-
Remote Rack POD Failure Detection: When the remote POD monitoring detects failure breaching threshold percentage, the POD becomes self-primary for that instance.
-
Remote Rack Role Monitoring: When the remote role monitoring detects that the rack is in Standy_error state, it becomes self-primary.
-
Multi-Compute Failure: When two or more servers are powered down, it triggers inter-rack redundancy failover.
