If your system is already in the switchover state, you can use the -simulate option to preview the results of a switchback operation.
The following example shows a successful verification of a switchback operation:
cluster4::*> metrocluster switchback -simulate (metrocluster switchback) [Job 130] Setting up the nodes and cluster components for the switchback operation...DBG:backup_api.c:327:backup_nso_sb_vetocheck : MCC Switch Back [Job 130] Job succeeded: Switchback simulation is successful. cluster4::*> metrocluster op show (metrocluster operation show) Operation: switchback-simulate State: successful Start Time: 5/15/2014 16:14:34 End Time: 5/15/2014 16:15:04 Errors: - cluster4::*> job show -name Me* Owning Job ID Name Vserver Node State ------ -------------------- ---------- -------------- ---------- 130 MetroCluster Switchback cluster4 cluster4-01 Success Description: MetroCluster Switchback Job - Simulation
