A customer has data in a LUN on an existing third-party SAN storage system that will be migrated to a new NetApp AFF A400 all-flash MetroCluster system. The host connected to the LUN is a Windows Server 2019 system.In this scenario, which two methods are supported? (Choose two.)
Answer(s): B,C
To migrate data from a LUN on an existing third-party SAN storage system to a new NetApp AFF A400 all-flash MetroCluster system, the supported methods include:Foreign LUN Import in online mode: This method allows for data migration without significant downtime, enabling the system to continue serving data while the migration process is ongoing. Foreign LUN Import in offline mode: This method involves taking the LUN offline during the migration process, which may be necessary in certain scenarios to ensure data integrity.For more details, refer to:NetApp Documentation on Foreign LUN ImportNetApp Community on LUN Import Methods
What needs to be done to create a consistent Snapshot copy of a LUN without disruptions?
Answer(s): B
To create a consistent Snapshot copy of a LUN without disruptions, it is necessary to quiesce I/O to the LUN. This process involves pausing or temporarily stopping the input/output operations to ensure that the data is in a consistent state when the snapshot is taken. This method is crucial for maintaining data integrity and consistency in the snapshot.For further details, refer to:NetApp Documentation on Snapshot ConsistencyNetApp Best Practices for Snapshot Management
An administrator has a NetApp AFF cluster supporting an application with twelve LUNs allocated across four volumes. There is a requirement to configure a Snapshot copy of all LUNs simultaneously as a single unit.Which NetApp ONTAP command should be used to configure this requirement?
Answer(s): D
To configure a Snapshot copy of all LUNs simultaneously as a single unit in an application with multiple LUNs spread across several volumes, the command vserver consistency-group create should be used. This command creates a consistency group that allows for coordinated snapshot creation across multiple volumes, ensuring that the snapshots are consistent with each other.For more information, you can refer to:NetApp ONTAP Consistency Group DocumentationNetApp Community Discussions on Consistency Groups
A customer asks for help cloning one database LUN from a SnapMlrror destination volume for testing the data with a new application.What command should the administrator use to clone the LUN?
Answer(s): C
To clone a LUN from a SnapMirror destination volume for testing purposes, the volume clone create command should be used. This command creates a FlexClone volume from the SnapMirror destination, making the LUN within it accessible for testing without disrupting the original volume.For more details, refer to:NetApp Documentation on Volume Clone CreateNetApp Community Discussion on LUN Cloning
