Assign a replication source and target to paired volumes

Contributors amgrissino netapp-pcarriga

After volumes are paired, you must 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 sent to a source volume to a remote target volume should the source volume become unavailable.

What you'll need

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

Steps

  1. Prepare the source volume:

    1. From the cluster that contains the volume you want to assign as source, select Management > Volumes.

    2. Click the Actions icon for the volume you want to assign as source and click Edit.

    3. In the Access drop-down list, select Read/Write.

      Important If you are reversing source and target assignment, this action will cause the volume pair to display the following message until a new replication target is assigned: PausedMisconfigured

      Changing access pauses volume replication and causes the transmission of data to cease. Be sure that you have coordinated these changes at both sites.

    4. Click Save Changes.

  2. Prepare the target volume:

    1. From the cluster that contains the volume you want to assign as target, select Management > Volumes.

    2. Click the Actions icon for the volume you want to assign as target and click Edit.

    3. In the Access drop-down list, select Replication Target.

      Important If you assign an existing volume as the replication target, the data on that volume will be overwritten. You should use a new target volume that contains no data and has the exact characteristics of the source volume, such as size, 512e setting, and QoS configuration. The target volume can be greater or equal in size to the source volume, but it cannot be smaller.

    4. Click Save Changes.
