The FLI Setup and Import workflow enables you to prepare and initiate third-party LUN imports. You can select the required foreign disks, create a LUN and take it offline, bring it online for read/write access, map the newly created LUN to an existing initiator group (igroup), set up the LUN import, and verify that the LUN is imported.
Migration of block-level data is a common scenario when you plan for storage consolidation in your data center, purchase or lease new storage arrays, or perform technology refreshes. This requires data migration from one array to another, usually from one vendor array to another. Foreign LUN import (FLI) is a storage-array based migration method that enables a minimally disruptive transition for importing your data from third-party array LUNs to NetApp LUNs.
FLI can be done in two ways, offline FLI or online FLI. The offline FLI functionality supported in Data ONTAP 8.3 and later, does not allow applications to access LUNs that are being migrated while FLI is active. The online FLI functionality supported in Data ONTAP 8.3.1 allows applications to continue to access data while the corresponding LUNs are being imported.
FLI for migrating data from third-party LUNs includes the following three initial phases:
The LUN import process occurs in five different phases. The following image illustrates the five phases of SAN data migration.
This workflow automates the planning phase of the data migration in which you can schedule and verify the LUN import.
You must ensure that certain requirements are met before executing the FLI Setup and Import workflow. You must be a cluster administrator for executing this workflow.
The FLI Setup and Import workflow enables you to organize source LUNs (third-party LUNs) and destination LUNs (NetApp LUNs) for migration. The workflow enables you to create LUNs and take them offline, bring them online, map the LUNs to the igroup, set up LUN import, and verify that LUN import is complete.
The following illustration displays the tasks involved in executing the workflow:
The FLI Setup and Import workflow enables you to set up the LUN import and verify the LUN import to a cluster. You can also select the required foreign disks, create a LUN and take it offline, map the newly created LUN to an existing igroup, set up LUN import, and verify that the LUN is imported.

You should have the following input parameters available for executing the workflow:
