Assigning a replication source and target to paired volumes

If you did not assign a volume to be the replication target during volume pairing, configuration is not complete. You can use this procedure to assign a source volume and its replication target volume. A replication source or target can be either volume in a volume pair. You can also use this procedure to redirect data from a source volume to a remote target volume should the source volume become unavailable.

Before you begin

You have access to the clusters containing the source and target volumes.

About this task

This procedure describes assigning source and replication volumes between two clusters using vCenter on the local and remote sites. For volumes not controlled by the vCenter Plug-in, you can alternately assign a source or replication volume using the Element web UI. For detailed instructions on deleting a cluster pair end from the Element web UI, see the user guide for NetApp Element software.

A replication source volume has read/write account access. A replication target volume can only be accessed by the replication source as read/write.
Best Practices: The target volume should contain no data and have the exact characteristics of the source volume, such as size, 512e setting, and QoS configuration. The target volume may be greater or equal in size to the source volume, but it cannot be smaller.

Steps

  1. From the NetApp Element Management extension point, select the cluster containing the paired volume that you want to use as the replication source.
  2. Select NetApp Element Management > Management.
  3. Click the Volumes sub-tab.
  4. From the Active view, select the check box for the volume you want to edit.
  5. Click Actions.
  6. In the resulting menu, select Edit.
  7. In the Access drop-down list, select Read/Write.
    Attention: If you are reversing source and target assignment, this action will cause the volume pair to display PausedMisconfigured until a new replication target is assigned. Changing access pauses volume replication and causes the transmission of data to cease. Be sure that you have coordinated these changes at both sites.
  8. Click OK.
  9. From the NetApp Element Management extension point, select the cluster containing the paired volume that you want to use as the replication target.
  10. Select NetApp Element Management > Management.
  11. Click the Volumes sub-tab.
  12. From the Active view, select the check box for the volume you want to edit.
  13. Click Actions.
  14. In the resulting menu, select Edit.
  15. In the Access drop-down list, select Replication Target.
    Attention: If you assign an existing volume as the replication target, the data on that volume will be overwritten. As a best practice, you should use a new volume as the replication target.
  16. Click OK.
