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.)

  1. SnapMirror Business Continuity
  2. Foreign LUN Import in online mode
  3. Foreign LUN Import in offline mode
  4. Client-side copy of the data

Answer(s): B,C

Explanation:

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.

What needs to be done to create a consistent Snapshot copy of a LUN without disruptions?

  1. Ensure that the LUN is the only one in the volume.
  2. Quiesce I/O to the LUN.
  3. Ensure that the LUN Is unmapped from the host.
  4. Map the LUN to a host.

Answer(s): B

Explanation:

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.

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?

  1. lun igroup create
  2. network port ifgrp create
  3. volume conversion start
  4. vserver consistency-group create

Answer(s): D

Explanation:

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.

NetApp ONTAP Consistency Group Documentation
NetApp 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?

  1. volume file clone create
  2. lun wove start
  3. volume clone create
  4. volume move start

Answer(s): C

Explanation:

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 Create
NetApp Community Discussion on LUN Cloning
