Prepare for cluster peering

Contributors NetAppZacharyWambold

Before creating a cluster peering relationship, you must verify that the time on each cluster is synchronized with an external Network Time Protocol (NTP) server, and determine the subnets, ports, and passphrases that you want to use.

  1. If you are running ONTAP 9.2 or earlier, determine the passphrase that you want to use for each cluster peer relationship.

    The passphrase must include at least eight characters.

    For the relationship between…​ The passphrase is…​

    Cluster A and Cluster B

    Starting with ONTAP 9.3, you can generate the passphrase from the remote cluster while creating the cluster peer relationship.

  2. Identify the subnets, IP addresses, and ports that you will use for intercluster LIFs.

    By default, the IP address is automatically selected from the subnet. If you want to specify the IP address manually, you must ensure that the IP address either is already available in the subnet or can be added to the subnet later. Information about subnets is available in the Network tab.

    The following table assumes that each cluster has four nodes. If a cluster has more than four nodes, you can record the ports on another piece of paper.

    Cluster A Cluster B

    Subnet (ONTAP 9.2 or earlier)

    IP address (starting with ONTAP 9.3, optional for ONTAP 9.2 or earlier)

    Node 1 port

    Node 2 port

    Node 3 port

    Node 4 port
