Configure the ONTAP Cloud Mediator for SnapMirror active sync

Contributors netapp-lenida

Beginning with ONTAP 9.17.1, you can use ONTAP Cloud Mediator to enable business continuity by monitoring the health of each cluster. ONTAP Cloud Mediator is a cloud-based service. When you use ONTAP Cloud Mediator with SnapMirror active sync, you must first confirm that BlueXP services and client information are configured and ensure proper cluster peering.

As with ONTAP Mediator, ONTAP Cloud Mediator provides a persistent and fenced store for high availability (HA) metadata used by the ONTAP clusters in a SnapMirror active sync relationship. ONTAP Cloud Mediator provides a synchronous node health query functionality to aid in quorum determination and serves as a ping proxy for controller liveliness detection.

Important If you are using SnapMirror active sync and ONTAP Mediator or ONTAP Cloud Mediator with ONTAP 9.17.1, you should review the Known problems and limitations in the ONTAP Release Notes for important information about these configurations.
Before you begin

Before you configure ONTAP Cloud Mediator, you should confirm the following information:

Steps

You can add ONTAP Cloud Mediator using System Manager or the ONTAP CLI.

System Manager

  1. Navigate to Protection > Overview > Mediator and select Add.

  2. In the Add a mediator window, select Cloud as the mediator type and enter the following information:

    • BlueXP organization ID

    • BlueXP client ID

    • BlueXP client secret

  3. Select the cluster peer.

  4. If you are using an HTTP proxy and it's not already configured, enter the HTTP proxy information for the local and remote hosts.

    It's recommended that you use a different proxy server for each cluster peer.

  5. Optional: If a root CA certificate needs to be installed in ONTAP, especially when using a proxy server, paste the certificate in the text box provided.

  6. Select Add.

  7. Navigate to Protection > Overview and check the status of the relationship between the SnapMirror active sync clusters and ONTAP Cloud Mediator.

CLI

  1. Configure ONTAP Cloud Mediator:
    snapmirror mediator add -peer-cluster <peerClusterName> -type cloud -bluexp-org-id <BlueXP Organization ID> -service-account-client-id <Service Account Client ID> -use-http-proxy-local <true|false> -use-http-proxy-remote <true|false>

  2. Check ONTAP Cloud Mediator status:
    snapmirror mediator show

    Example:

    C1_cluster::> snapmirror mediator show
Mediator Address Peer Cluster     Connection Status Quorum Status Type
