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:
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.
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.
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.
The following illustration displays the tasks involved in executing the 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.
You should have the following input parameters available for executing the workflow:
You should verify that the root volumes are available in the destination aggregate by using one of the following methods:
The command lists all the volumes contained in the aggregates of the selected cluster.
