Aux-far site and active orchestrator failure and failback
If active orchestrator is failed, you can shutdown the active orchestrator for standby orchestrator to takeover.
Using the command-line interface
The following cases are the failure and failback of active or standby orchestrator:
- Aux-far site failure with both orchestrators and failback
-
- If Aux-far site with orchestrator is failed, standby orchestrator status appears as
disconnected.

- If Aux-far site with orchestrator is failed, standby orchestrator status appears as
disconnected.
- Active orchestrator failure and failback
-
- To validate the status of both orchestrators, enter ls3siteconfig
command.

scenario.
[root@rhel7host108 home]# shutdown - Standby orchestrator takes over the role of active orchestrator after five retries on
standby orchestrator. It might take 8 minutes to start data cycling on standby orchestrator. After
taking over the role of active orchestrator, as there is only one orchestrator active, standby
orchestrator appears as standby_offline.
