Resynchronizing protection relationships from the Health/Volume details page

Contributors netapp-adityaw

You can resynchronize data on a SnapMirror or SnapVault relationship that was broken and then the destination was made read/write so that data on the source matches the data on the destination. You might also resynchronize when a required common Snapshot copy on the source volume is deleted causing SnapMirror or SnapVault updates to fail.

Before you begin

  • You must have the OnCommand Administrator or Storage Administrator role.

  • You must have set up OnCommand Workflow Automation.


  1. From the Protection tab of the Health/Volume details page, locate in the topology the protection relationship that you want to resynchronize and right-click it.

  2. Select Resynchronize from the menu.

    Alternatively, from the Actions menu, select Relationship > Resynchronize to resynchronize the relationship for which you are currently viewing the details.

    The Resynchronize dialog box is displayed.

  3. In the Resynchronization Options tab, select a transfer priority and the maximum transfer rate.

  4. Click Source Snapshot Copies; then, in the Snapshot Copy column, click Default.

    The Select Source Snapshot Copy dialog box is displayed.

  5. If you want to specify an existing Snapshot copy rather than transferring the default Snapshot copy, click Existing Snapshot Copy and select a Snapshot copy from the list.

  6. Click Submit.

    You are returned to the Resynchronize dialog box.

  7. If you selected more than one source to resynchronize, click Default for the next source for which you want to specify an existing Snapshot copy.

  8. Click Submit to begin the resynchronization job.

    The resynchronization job is started, you are returned to the Health/Volume details page and a jobs link is displayed at the top of the page.

  9. Click View Jobs on the Health/Volume details page to track the status of each resynchronization job.

    A filtered list of jobs is displayed.

  10. Click the Back arrow on your browser to return to the Health/Volume details page.

    The resynchronization job is finished when all job tasks successfully complete.
