Which ONTAP command initiates a MetroCluster switchover?

The correct ONTAP command to initiate a MetroCluster switchover is metrocluster switchover. This command is executed from the ONTAP command-line interface (CLI) on the surviving cluster (the disaster recovery site). It begins the process of failing over storage services from the disaster site to the partner site. The command can be run with various parameters, such as -simulate to perform a validation check without executing the switchover. This is a critical administrative command used for disaster recovery testing or in response to a real site failure.

B. cluster switchover run: This command syntax is incorrect. cluster commands manage local cluster operations, not the MetroCluster disaster recovery function.

C. system switchover start: This is not a valid ONTAP command for initiating a MetroCluster switchover.

D. storage switchover: This is not a valid ONTAP command. The correct command family is metrocluster.
