Set up MetroCluster IP peering

Contributors netapp-aoife

Beginning with ONTAP 9.8, you can manage MetroCluster IP configuration operations with System Manager. After setting up two clusters, you set up peering between them.

Before you begin

Set up two clusters. See the Set up a MetroCluster IP site procedure.

Certain steps of this process are performed by different system administrators located at the geographical sites of each cluster. For the purposes of explaining this process, the clusters are called "Site A cluster" and "Site B cluster".

Perform the peering process from Site A

This process is performed by a system administrator at Site A.

Steps

  1. Log in to Site A cluster.

  2. In System Manager, select Dashboard from the left navigation column to display the cluster overview.

    The dashboard shows the details for this cluster (Site A). In the MetroCluster section, Site A cluster is shown on the left.

  3. Click Attach Partner Cluster.

  4. Enter the details of the network interfaces that allow the nodes in Site A cluster to communicate with the nodes in Site B cluster.

  5. Click Save and Continue.

  6. On the Attach Partner Cluster window, select I do not have a passphrase. This lets you generate a passphrase.

  7. Copy the generated passphrase and share it with the system administrator at Site B.

  8. Select Close.

Perform the peering process from Site B

This process is performed by a system administrator at Site B.

Steps

  1. Log in to Site B cluster.

  2. In System Manager, select Dashboard to display the cluster overview.

    The dashboard shows the details for this cluster (Site B). In the MetroCluster section, Site B cluster is shown on the left.

  3. Click Attach Partner Cluster to start the peering process.

  4. Enter the details of the network interfaces that allow the nodes in Site B cluster to communicate with the nodes in Site A cluster.

  5. Click Save and Continue.

  6. On the Attach Partner Cluster window, select I have a passphrase. This lets you enter the passphrase that you received from the system administrator at Site A.

  7. Select Peer to complete the peering process.

What's next?

After the peering process successfully completes, you configure the clusters. See Configure a MetroCluster IP site.
