A customer wants to have their MetroCluster IP automatically switch over in the event of a site disaster. Which two NetApp features can the customer…

To achieve an automatic unplanned switchover (AUSO) in a MetroCluster IP environment, a third-site witness component is required. This component monitors the health of both sites and, in the event of a site failure, helps the surviving site take over operations automatically. NetApp provides two solutions for this purpose: the ONTAP Mediator service and the MetroCluster TieBreaker software. Both act as a quorum witness to prevent split-brain scenarios and can initiate an AUSO when a disaster is detected, ensuring business continuity without manual intervention.

A. BlueXP observability: This is a monitoring and management service within the BlueXP platform; it provides insights but does not initiate an automatic switchover.

B. Active IQ Unified Manager: This tool is used for monitoring, reporting, and managing the health and performance of ONTAP systems, but it does not trigger the MetroCluster switchover process.

E. Data Broker: This is not a recognized NetApp component or feature for automating MetroCluster switchover operations.

Section: "Automatic unplanned switchover," Page 10.

Quote: "MetroCluster IP configurations support automatic unplanned switchover (AUSO). This capability requires a third-site witness, either the ONTAP Mediator or the MetroCluster Tiebreaker software." This statement directly confirms that both Mediator and TieBreaker are the features used for this purpose.

2. NetApp ONTAP Documentation: Install the ONTAP Mediator service for MetroCluster IP configurations.

Section: "ONTAP Mediator service overview."

Quote: "The ONTAP Mediator service provides a third-site witness for a four-node MetroCluster IP configuration. It monitors the MetroCluster IP configuration and can assist in the negotiation of an automatic unplanned switchover (AUSO) if a site disaster occurs."

3. NetApp ONTAP Documentation: Install the MetroCluster Tiebreaker software.

Section: "MetroCluster Tiebreaker software overview."

Quote: "The MetroCluster Tiebreaker software monitors the MetroCluster configuration and can declare a disaster at one of the sites and trigger an automatic unplanned switchover to the other site."
