Move Root Volumes Back To Their Original Aggregates

After successfully upgrading clustered Data ONTAP, you must move the root volumes in load-sharing mirror relationship back to their original aggregates. The Move Root Volumes Back To Their Original Aggregates workflow enables you to move the root volumes to their source aggregates by using the volume move operation.

The workflow enables you to select the appropriate cluster to which the root volumes have to be moved, and then move the root volumes to the original aggregates in the specified cluster.

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

Prerequisites for executing the Move Root Volumes Back To Their Original Aggregates workflow

You must ensure that certain requirements are met before executing the Move Root Volumes Back To Their Original Aggregates 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 8.2 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.
  • The cluster must be available and running clustered Data ONTAP version later than 8.2.
  • Snapmirror license must be enabled in the source cluster.

What happens when you execute the Move Root Volumes Back To Their Original Aggregates workflow

The Move Root Volumes Back To Their Original Aggregates workflow enables you to move the root volumes in load-sharing mirror relationship back to the original aggregates after you have completed a Data ONTAP upgrade.

The workflow executes the volume move operation to move the root volumes in the SVMs back to the original aggregates in the specified cluster. The workflow ensures that all the volumes are moved in parallel. The workflow moves the volumes until the volume move limit (8 volumes) is reached, and then the next set of 8 volumes are moved.

If any failure occurs during the volume move operation for a set of volumes, the workflow continues to execute the volume move operation on the next set of volumes that are in queue. Failure and progress information is recorded in the WFA log, which you can access from Execution > Move Root Volumes Back To Their Original Aggregates.

Note: The workflow does not include the verification procedure.

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

Executing the Move Root Volumes Back To Their Original Aggregates workflow

After upgrading to a later version of Data ONTAP, you should move the root volumes back to their original aggregates. The Move Root Volumes Back To Their Original Aggregates workflow enables you to move the root volumes in load-sharing mirror relationship to the original aggregates in the source cluster.

Before you begin

  • The workflow pack must be downloaded from the Storage Automation Store.
  • You must have reviewed the prerequisites for executing the workflow.
  • The root volumes must be moved to the destination aggregates using the Move Root Volumes to a Target Node workflow.

About this task

You should have the cluster name as the input parameter.

Steps

  1. Log in to WFA by providing the necessary credentials.
  2. Click Portal > Data Protection > Move Root Volumes Back To Their Original Aggregates.
    Tip: You can use the filter () to locate the workflow.
  3. Click the Execute icon ().
    The Execute Workflow 'Move Root Volumes Back To Their Original Aggregates' dialog box is displayed.
  4. Select the appropriate cluster.
  5. Optional: Click Preview to validate your workflow before executing it.
  6. 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.

After you finish

You should verify that the root volumes are available in the original aggregate by using one of the following methods:

  • Log in to OnCommand Unified Manager and click Storage > Volumes to display the root volumes.
    Note: Due to monitoring intervals in Unified Manager, there might be a delay in displaying the volume details in the Unified Manager UI.
  • Log in to the Data ONTAP CLI and run the volume show command.

    The command lists all the volumes contained in the aggregates of the selected cluster.
