The metrocluster switchback command initiates the process of returning data service from the disaster recovery (DR) site back to the original production site after a failure has been resolved. This command is executed after the failed site has been repaired and its aggregates have been successfully healed and resynchronized. The switchback operation non-disruptively transfers control and client access back to the original cluster, restoring the configuration to its normal, pre-switchover state.

cluster switchback start is not a valid ONTAP command for MetroCluster operations.

storage switchback is not a valid ONTAP command; storage commands manage physical resources, not MetroCluster states.

metrocluster restore is used to restore the MetroCluster configuration from a backup file, which is a different procedure from a switchback.
