NS0-521 Exam Dumps : Implementation Engineer - SAN ONTAP Exam

When using Foreign LUN Import (FLI) for migrating LUNs from third-party SAN arrays to a NetApp ONTAP system, one of the requirements is to have at least one Fibre Channel (FC) port configured in target mode on the destination NetApp ONTAP cluster. This configuration is necessary to facilitate the migration process as the target mode port will accept and manage incoming data from the source SAN arrays.

NetApp Documentation on FLI

For configuring LUNs to share with ESXi hosts for datastores in an SVM created for FCP traffic, the following steps are necessary after creating the LUN:

Create an igroup with the ESXi hosts' WWPNs: This step involves defining an initiator group that includes the WWPNs of the ESXi hosts that need access to the LUN.

Map the LUNs to the igroup: This step assigns the LUN to the created igroup, allowing the ESXi hosts to access the LUN.

NetApp Documentation on LUN and igroup Configuration

The recommended setting for using the NetApp ONTAP LUN fractional reserve is to set the space guarantee to "volume". This setting ensures that the required space for overwrites in the volume is reserved, preventing potential write failures when snapshot copies are created. This setup helps in maintaining the performance and reliability of the storage system by ensuring there is always enough space allocated for the LUN.
