Create cluster peer relationships

Contributors NetAppZacharyWambold netapp-ivanad

You can create an authenticated cluster peer relationship to connect clusters so that the clusters in the peer relationship can communicate securely with each other.

Before you begin
  • You must have reviewed and completed the requirements for performing this task.

  • You must have created intercluster logical interfaces (LIFs).

  • You should be aware of which version of ONTAP each cluster is running.

About this task
  • If you want to create a peer relationship with a cluster running Data ONTAP 8.2.2 or earlier, you must use the CLI.

  • You can create a peer relationship between a cluster running ONTAP 9.5 and a cluster running ONTAP 9.6. However, encryption is not supported in ONTAP 9.5, so the peer relationship cannot be encrypted.

  • In a MetroCluster configuration, when you create a peer relationship between the primary cluster and an external cluster, it is a best practice to create a peer relationship between the surviving site cluster and the external cluster as well.

  • You can create a custom passphrase or you can use the system-generated passphrase to authenticate the cluster peer relationship. However, the passphrases of both clusters must match.

Steps
  1. Click Configuration > Advanced Cluster Setup.

  2. In the Target Cluster Intercluster LIF IP addresses field, enter the IP addresses of the remote cluster’s intercluster LIFs.

  3. If you are creating a peer relationship between a cluster running ONTAP 9.5 and a cluster running ONTAP 9.6, select the checkbox.

    The peer relationship will not be encrypted. If you do not select the checkbox, the peer relationship will not be established.

  4. In the Passphrase field, specify a passphrase for the cluster peer relationship.

    If you create a custom passphrase, the passphrase will be validated against the passphrase of the peered cluster to ensure an authenticated cluster peer relationship.

    If the names of the local cluster and remote cluster are identical, and if you are using a custom passphrase, an alias is created for the remote cluster.

  5. To generate a passphrase from the remote cluster, enter the management IP address of the remote cluster.

  6. Initiate cluster peering.

    If you want to…​ Do this…​

    Initiate cluster peering from the initiator cluster

    Click Initiate Cluster Peering.

    Initiate cluster peering from the remote cluster (Applicable if you have created a custom passphrase)

    1. Enter the management IP address of the remote cluster.

    2. Click the Management URL link to access the remote cluster.

    3. Click Create Cluster Peering.

    4. Specify the intercluster LIF IP addresses and passphrase of the initiator cluster.

    5. Click Initiate Peering.

    6. Access the initiator cluster, and then click Validate Peering.

What to do next

You should specify the SVM details in the SVM Peering window to continue with the peering process.
