Which feature can automate switchover in a MetroCluster IP disaster scenario?

• A. BlueXP observability
• B. Active IQ Unified Manager
• C. MetroCluster TieBreaker
• D. ONTAP Mediator service

Answer: (D)

In MetroCluster IP disaster recovery, automatic switchover hinges on a mechanism that can coordinate and initiate the switch to the surviving site without manual steps. The ONTAP Mediator service serves as that coordinating agent. It acts as a third voter in the MetroCluster quorum and orchestrates a clean, automatic switchover when one site becomes unavailable or its connectivity is compromised. This minimizes downtime and preserves data integrity by letting the healthy cluster take over operations in a controlled, automated way.

Other options don’t provide this built-in automatic switchover capability. BlueXP observability focuses on visibility and monitoring, not triggering a failover. Active IQ Unified Manager can manage and plan workflows at a higher level, but it isn’t the component that directly performs the MetroCluster switchover. MetroCluster TieBreaker offers the decision vote to prevent split-brain, but it doesn’t execute the failover itself—the mediator service handles the automatic switchover orchestration.
