Pairing clusters with a pairing key

If you have Cluster Admin access to a local cluster but not the remote cluster, you can pair the clusters using a pairing key. A pairing key is generated on a local cluster and then sent securely to a Cluster Admin at a remote site to establish a connection and complete the cluster pairing for real-time replication.

About this task

This procedure describes cluster pairing between two clusters using vCenter on the local and remote sites. For clusters not controlled by the vCenter Plug-in, you can alternately start or complete cluster pairing using the Element web UI. For detailed instructions on starting or completing cluster pairing from the Element web UI, see the user guide for NetApp Element software.

Steps

  1. From the vCenter that contains the local cluster, select NetApp Element Management > Protection.
    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 Cluster Pairs sub-tab.
  3. Click Create Cluster Pairing.
  4. In the Create Cluster Pairing dialog box, select Inaccessible Cluster.
  5. Click Generate Key.
    Note: This action generates a text key for pairing and creates an unconfigured cluster pair on the local cluster. If you do not complete the procedure, you will need to manually delete the cluster pair.
  6. Copy the cluster pairing key to your clipboard.
  7. Click Close.
  8. Make the pairing key accessible to the Cluster Admin at the remote cluster site.
    Note: The cluster pairing key contains a version of the MVIP, user name, password, and database information to permit volume connections for remote replication. This key should be treated in a secure manner and not stored in a way that would allow accidental or unsecured access to the user name or password.
    Attention: Do not modify any of the characters in the pairing key. The key becomes invalid if it is modified.
  9. From the vCenter that contains the remote cluster, select NetApp Element Management > Protection
    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.
    Note: You can alternatively complete the pairing using the Element UI.
  10. Click the Cluster Pairs sub-tab.
  11. Click Complete Cluster Pairing.
    Note: Wait for the loading spinner to disappear before proceeding to the next step. If an unexpected error occurs during the pairing process, check for and manually delete any unconfigured cluster pairs on the local and remote cluster and perform the pairing again.
  12. Paste the pairing key from the local cluster in the Cluster Pairing Key field.
  13. Click Pair Cluster.
  14. After the task completes and returns you to the Cluster Pair page, verify that the cluster pair is connected.
  15. On the remote cluster, select NetApp Element Management > Protection or use the Element UI to verify that the cluster pair is connected.
