Pairing volumes using known credentials

You can pair a local volume with another volume on a remote cluster. Use this method if there is Cluster Admin access to both clusters on which volumes are to be paired. This method uses the volume ID of the volume on the remote cluster to initiate a connection.

Before you begin

Steps

  1. From the vCenter that contains the local cluster, select NetApp Element Management > Management.
    Note: If two or more clusters are added, ensure that the cluster you intend to use for the task is selected in the navigation bar.
  2. Click the Volumes sub-tab.
  3. From the Active view, select the check box for the volume you want to pair.
  4. Click Actions.
  5. In the resulting menu, click Volume Pairing
  6. In the Volume Pairing dialog box, select one of the following:
    • Volume Creation: Select this method to create a replication target volume on the remote cluster. This method can only be used on remote clusters that are controlled by a NetApp Element Plug-in for vCenter Server.
    • Volume Selection: Select this method if the remote cluster for the target volume is controlled by a NetApp Element Plug-in for vCenter Server.
    • Volume ID: Select this method if the remote cluster for the target volume has known credentials that are outside of the NetApp Element Plug-in for vCenter Server configuration.
  7. Select a Replication Mode from the drop-down list.
    • Real-time (Synchronous): Writes are acknowledged to the client after they are committed on both the source and target clusters.
    • Real-time (Asynchronous): Writes are acknowledged to the client after they are committed on the source cluster.
    • Snapshots Only: Only snapshots created on the source cluster are replicated. Active writes from the source volume are not replicated.
  8. If you selected Volume Creation as the pairing mode option, do the following:
    1. Select a paired cluster from the drop-down list.
      Note: This action populates the available accounts on the cluster to be selected in the next step.
    2. Select an account on the target cluster for the replication target volume.
    3. Enter a replication target volume name.
      Note: Volume size cannot be adjusted during this process.
  9. If you selected Volume Selection as the pairing mode option, do the following:
    1. Select a paired cluster from the drop-down list.
      Note: This action populates the available volumes on the cluster to be selected in the next step.
    2. Optional: Click the set remote volume to Replication Target option if you want to set the remote volume as the target in the volume pairing. The local volume, if set to read/write, becomes the source in the pair.
      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.
      Note: You can also assign replication source and target later in the pairing process from Volumes > Actions > Edit. You must assign a source and target to complete the pairing.
    3. Select a volume from the list of available volumes.
  10. If you selected Volume ID as the pairing mode option, do the following:
    1. Select a paired cluster from the drop-down list.
    2. If the cluster is not registered with the plug-in, enter a cluster administrator user ID.
    3. If the cluster is not registered with the plug-in, enter a cluster administrator password.
    4. Enter a volume ID.
    5. Click the set remote volume to Replication Target option if you want to set the remote volume as the target in the volume pairing. The local volume, if set to read/write, becomes the source in the pair.
      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.
      Note: You can also assign replication source and target later in the pairing process from Volumes > Actions > Edit. You must assign a source and target to complete the pairing.
  11. Click Pair.
    Note: After you confirm the pairing, the two clusters begin the process of connecting the volumes. During the pairing process, you can see progress messages in the Volume Status column on the Volume Pairs page.
    Attention: If you have not yet assigned a volume to be the replication target, the pairing configuration is not complete. The volume pair displays PausedMisconfigured until the volume pair source and target are assigned. You must assign a source and target to complete the volume pairing.
  12. Select Protection > Volume Pairs on either cluster.
  13. Verify the status of the volume pairing.
