GR Triggers

Geographic Redundancy (GR) supports the following GR triggers:

  • CLI-based switchover: Manual CLI commands are used to switch the roles and trigger GR failover.

  • BFD link failover detection: When both the BFD links between the connected rack and the leafs are down, GR failover is triggered.

  • Local Site POD failure detection: When threshold percentage of POD replica-sets failing is greater than the configured threshold value, GR failover is triggered.

  • Remote Site POD failure detection: When the remote POD monitoring detects failure breaching threshold percentage, the POD becomes self-primary for that instance.

  • Remote Site 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 GR failover.
