Managing data tiering from your clusters

Contributors netapp-bcammett

Now that you’ve discovered and tiered data from your first ONTAP cluster, you can tier data from additional volumes, discover additional clusters, and more.

Discovering additional clusters

Add additional ONTAP clusters at any time to start tiering inactive data from those clusters.

  1. From the Cluster Dashboard, click the following icon:

    A screenshot that shows the icon for discovering additional clusters.

  2. Enter the cluster management IP address and the user name and password of an account that has administrator-level privileges.

  3. Click Discover Cluster.

    If you already have an existing Service Connector, then Cloud Tiering automatically attempts to use that Service Connector.

  4. If you have an existing Service Connector and Cloud Tiering can’t use it, then you’ll need to do one of two things:

    • Click Add Service Connector to create a new Service Connector.

    • Check the status and connectivity of any existing Service Connectors and then try to discover the cluster again.

What’s next?

Click Tier Volumes to start tiering inactive data from the cluster.

Tiering data from additional volumes

Set up data tiering for additional volumes at any time—​for example, after creating a new volume.

  1. From the Cluster Dashboard, click Tier Volumes.

  2. Choose a tiering policy for each volume and click Continue.

    You don’t need to configure the object storage because it was already configured when you initially set up tiering for the cluster. ONTAP will tier inactive data from these volumes to the same object store.

Changing a volume’s tiering policy

Changing the tiering policy for a volume changes how ONTAP tiers cold data to object storage. The change starts from the moment that you change the policy—​it changes only the subsequent tiering behavior for the volume.

  1. From the Cluster Dashboard, click Tier Volumes for the cluster.

  2. Choose a tiering policy for each volume and click Continue.

Reviewing tiering info for a cluster

You might want to see how much data is in the cloud tier and how much data is on disks. Or, you might want to see the amount of hot and cold data on the cluster’s disks. Cloud Tiering provides this information for each cluster.

  1. From the Cluster Dashboard, click More info for a cluster.

  2. Review details about the cluster.

    Here’s an example:

Fixing operational health

Failures can happen. When they do, Cloud Tiering displays a "Failed" operational health status on the Cluster Dashboard. The health reflects the status of the ONTAP system and the Service Connector.

  1. Identify any clusters that have an operational health of "Failed."

  2. Hover over the A screenshot of the i icon that shows the failure reason icon to see the failure reason.

  3. Correct the issue:

    1. Verify that the ONTAP cluster is operational and that it has an inbound and outbound connection to your object storage provider.

    2. Verify that the Service Connector is running and that it has outbound connections to the Cloud Tiering service, to the object store, and to the ONTAP clusters that it discovers.

      The name of the Service Connector instance/virtual machine is prefixed with "Service-connector."
