Move Root Volumes to a Target Node Workflow

Before upgrading to the latest Data ONTAP version, you must move the root volumes of the Storage Virtual Machines (SVMs) that are in load-sharing mirror relationship to the last upgrading node. The Move Root Volumes to a Target Node workflow enables you to move the root volumes to the selected aggregates.

The workflow enables you to select the destination cluster, the node, and the aggregate to which the root volumes have to be moved, and then move the root volumes in load-sharing mirror relationship to the specified aggregates.

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

Prerequisites for executing the Move Root Volumes to a Target Node workflow

You must ensure that certain requirements are met before executing the Move Root Volumes to a Target Node 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 target node must be available and running a Data ONTAP version later than 8.2.
  • Snapmirror license must be enabled on the destination cluster.

What happens when you execute the Move Root Volumes to a Target Node workflow

The Move Root Volumes to a Target Node workflow enables you to move the root volumes in load-sharing mirror relationships to the selected aggregates in the target node before you plan an upgrade to a later version of Data ONTAP.

The volumes in the SVM are moved in a round-robin method. For example, if there are 20 volumes in the SVM, 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 a 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 to a Target Node.

You must regularly monitor the logs to check for any volume move errors and take necessary action. For example, a volume move operation fails if the aggregate has gone offline during the workflow execution. You must bring the aggregate back online, and then execute the workflow again.

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 to a Target Node workflow

When you plan to upgrade to a later version of Data ONTAP, you should move the root volumes of your Storage Virtual Machines (SVMs). The Move Root Volumes to a Target Node workflow enables you to move the root volumes with load-sharing mirrors to the selected aggregates.

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
  • Destination aggregates

Steps

  1. Log in to WFA by providing the necessary credentials.
  2. Click Portal > Data Protection > Move Root Volumes to a Target Node.
    Tip: You can use the filter () to locate the workflow.
  3. Click the Execute icon ().
    The Execute Workflow 'Move Root Volumes to a Target Node' dialog box is displayed.
  4. Select the cluster.
  5. Select the target node.
  6. Select the aggregates of the specified target node.
  7. Optional: Click Preview to validate your workflow before executing it.
  8. 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 destination aggregate by using one of the following methods:

  • Log in to OnCommand Unified Manager and click Storage > Volumes to view the root volumes.
    Note: Due to monitoring intervals in Unified Manager, there might be a delay in displaying the volume details.
  • 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.
