Pairing volumes using a pairing key

If you do not have cluster admin credentials for a remote cluster, you can pair a volume with another volume on a remote cluster using a pairing key.

Before you begin

Steps

  1. Select Management > Volumes.
  2. Click Actions icon for the volume you want to pair.
  3. Click Pair.
  4. In the Pair Volume dialog box, select Start Pairing.
  5. Select I Do Not to indicate that you do not have access to the remote cluster.
  6. Select a Replication Mode from the list:
    • Real-time (Asynchronous): Writes are acknowledged to the client after they are committed on the source cluster.
    • Real-time (Synchronous): Writes are acknowledged to the client after they are committed on both the source and target clusters.
    • Snapshots Only: Only snapshots created on the source cluster are replicated. Active writes from the source volume are not replicated.
  7. Click Generate Key.
    Note: This action generates a text key for pairing and creates an unconfigured volume pair on the local cluster. If you do not complete the procedure, you will need to manually delete the volume pair.
  8. Copy the pairing key to your computer's clipboard.
  9. Make the pairing key accessible to the cluster admin at the remote cluster site.
    Note: The volume pairing key should be treated in a secure manner and not used in a way that would allow accidental or unsecured access.
    Attention: Do not modify any of the characters in the pairing key. The key becomes invalid if it is modified.
  10. In the remote cluster Element UI, select Management > Volumes.
  11. Click the Actions icon for the volume you want to pair.
  12. Click Pair.
  13. In the Pair Volume dialog box, select Complete Pairing.
  14. Paste the pairing key from the other cluster into the Pairing Key box.
  15. Click Complete Pairing.

    After you confirm the pairing, the two clusters begin the process of connecting the volumes for pairing. During the pairing process, you can see messages in the Volume Status column of the Volume Pairs window. The volume pair displays PausedMisconfigured until the volume pair source and target are assigned.
