Breaking LUN Import Relationship workflow

For storage consolidation in your data center, after you have migrated data from third-party LUNs to a NetApp cluster, you should break the source and destination LUN relationship. The Breaking LUN Import Relationship workflow enables you to break the LUN import relationship.

When you plan storage consolidation in your data center, you should migrate data from one array to another. Foreign LUN import (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:

The actual LUN import happens in five different phases. The following image illustrates the five phases of SAN data migration.


The image displays the phases in SAN data migration.

This workflow automates the breaking of LUN import relationship in the post-cutover phase.

The following sections provide details about the workflow and how to execute the workflow:

Prerequisite for executing the Breaking LUN Import Relationship workflow

You must ensure that certain requirements are met before executing the Breaking LUN Import Relationship workflow. You must be a cluster administrator for executing this workflow.

  • Your system must be running clustered Data ONTAP.
    Note: This workflow is qualified to work with Data ONTAP 8.3 and later.
  • OnCommand Workflow Automation (WFA) 3.0 or later must be installed.
  • You must have added OnCommand Unified Manager 6.2 or later as a data source in WFA and obtained the latest Unified Manager data.
  • Data from the third-party LUNs must have been migrated using the Migrating Third-party LUNs to a Cluster workflow.

What happens when you execute the Breaking LUN Import Relationship workflow

The Breaking LUN Import Relationship workflow enables you break the relationship between source and destination LUNs after you import them to NetApp cluster.

The following illustration displays the tasks involved in executing the workflow:

Executing the Breaking LUN Import Relationship workflow

After you import third-party LUNs to a NetApp cluster, the Breaking LUN Import Relationship workflow enables you to delete the relationship between the source and destination LUNs.

Before you begin

  • The workflow pack must be downloaded from the Storage Automation Store.
  • You must have reviewed the prerequisites for executing the workflow.

About this task

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

  • Cluster name
  • Node name
  • Storage Virtual Machine (SVM) name
  • LUN import relationships for deletion

Steps

  1. Log in to WFA by providing the necessary credentials.
  2. Click Portal > Migration > Breaking LUN Import Relationship.
    Tip: You can use the filter () to locate the workflow.
  3. Click the Execute icon ().
    The Execute Workflow 'Breaking LUN Import Relationship' dialog box is displayed.
  4. Select the cluster.
  5. Select the node.
  6. Select the SVM.
  7. Select the LUN import relationships that you want to break.
  8. Specify if you want to delete a LUN whose import has failed.
  9. Optional: Click Preview to validate your workflow before executing it.
  10. Click Execute.
    You can also schedule the workflow for execution at a later date and time by selecting the Choose Date and Time for Execution check box.
