Foreign LUN import (FLI) involves many LUN migration jobs such as migration in progress, failed, paused, stopped, and completed migrations. The Managing LUN Migrations Jobs workflow enables you to effectively manage these LUN migrations jobs.
When you plan for a storage consolidation in your data center, you should migrate data from one array to another. FLI is a storage-array based migration method that enables a smooth transition for importing your data from third-party arrays to NetApp clusters.
FLI for third-party LUN data migration includes the following three pre-phases:
This phase involves backing up foreign LUNs, configuring SAN host, and configuring the foreign array.
This phase involves taking the host applications offline, ensuring that there is no further access from the SAN host to the foreign LUNs outside of clustered Data ONTAP, and presenting NetApp LUNs to the SAN host by adding them to the igroup.
This phase involves bringing the host back online, initiating import for one or more foreign LUNs, and breaking the relationship when the import is complete.
The actual LUN import happens in five different phases. The following image illustrates the five phases of SAN data migration.
This workflow automates the verification phase of the data migration in which you can monitor the progress of LUN migration.
The following sections provide details about the workflow and how to execute the workflow:
You must ensure that certain requirements are met before executing the Managing LUN Migration Jobs workflow. You must be a cluster administrator for executing this workflow.
The Managing LUN Migrations Jobs workflow enables you to effectively manage LUN migrations jobs such as migration in progress, failed, paused, stopped, and completed migrations.
The migration jobs are as follows:
You might want to temporarily pause LUN import when the system load is high. After the system load become low, you can resume the LUN import.
If any failure occurs in the system during LUN import, you can check which LUN import failed and take necessary actions.
After the import is complete, you can stop the data migration.
You can keep track of all the completed LUN import operations.
The following illustration displays the tasks involved in executing the workflow:
