What do you need to configure to fulfill this requirement?
To ensure an automatic switchover to the surviving site in case of a site disaster in a MetroCluster IP configuration, you need to configure the 'automated unplanned switchover' feature. This feature allows the system to automatically switch over to the surviving site without manual intervention during an unplanned outage, fulfilling the requirement for automatic switchover. The ONTAP Mediator service supports this feature by monitoring the status and health of the sites, but it is not the primary feature to be configured. Instead, the automated unplanned switchover setting needs to be correctly configured to ensure seamless operation during a disaster scenario.
Starting with ONTAP 9.7, the ONTAP Mediator service can assist the MetroCluster IP configuration in performing an automatic unplanned switchover by providing a physically separate repository for status information.
A is correct
No, option A is not correct. ONTAP Mediator service is a component that enables automated unplanned switchover, but it is not the feature that you need to configure. You need to enable AUSO on each MetroCluster node by using the metrocluster node modify -node * -auto-switchover true command. This will allow the nodes to automatically take over their partner’s storage in case of a site disaster. ONTAP Mediator service will monitor the health and connectivity of both sites and initiate the failover when necessary.
It's not C (AUSO). This option is set to true by default. It needs to be modified only after failover. "he AUSO option is set to true by default during MetroCluster configuration so that automatic switchover occurs in the event of the failures listed above." https://library.netapp.com/ecmdocs/ECMP12458277/html/GUID-B3F7418D-759E-4929-9FB1-B06186E099AA.html
A In MetroCluster IP configurations, the system can use the ONTAP Mediator to detect failures and perform a Mediator-assisted automatic unplanned switchover (MAUSO).
