If the best-practice recommendation that ONTAP provides for automatically adding a local tier is appropriate in your environment, you can accept the recommendation and let ONTAP add the local tier.

Note Prior to ONTAP 9.7, System Manager uses the term aggregate to describe a local tier. Regardless of your ONTAP version, the ONTAP CLI uses the term aggregate. To learn more about local tiers, see Disks and local tiers.
Before you begin

Disks must be owned by a node before they can be used in a local tier. If your cluster is not configured to use automatic disk ownership assignment, you must assign ownership manually.

Learn more about the commands described in this procedure in the ONTAP command reference.

System Manager
Steps

  1. In System Manager, click Storage > Tiers.

  2. From the Tiers page, click Add local tier icon to create a new local tier:

    The Add Local Tier page shows the recommended number of local tiers that can be created on the nodes and the usable storage available.

  3. Click Recommended details to view the configuration recommended by System Manager.

    System Manager displays the following information beginning with ONTAP 9.8:

    • Local tier name (you can edit the local tier name beginning with ONTAP 9.10.1)

    • Node name

    • Usable size

    • Type of storage

    Beginning with ONTAP 9.10.1, additional information is displayed:

    • Disks: showing the number, size, and type of the disks

    • Layout: showing the RAID group layout, including which disks are parity or data and which slots are unused.

    • Spare disks: showing the node name, the number and size of spare disks, and the type of storage.

  4. Perform one of the following steps:

    Then do this…

    Accept the recommendations from System Manager.

    Proceed to the step for configuring the Onboard Key Manager for encryption.

    Manually configure the local tiers and not use the recommendations from System Manager.

    Proceed to Add a local tier manually:

    • For ONTAP 9.10.1 and earlier, follow the steps to use the CLI.

    • Beginning with ONTAP 9.11.1, follow the steps to use System Manager.

  5. (Optional): If the Onboard Key Manager has been installed, you can configure it for encryption. Check the Configure Onboard Key Manager for encryption check box.

    1. Enter a passphrase.

    2. Enter the passphrase again to confirm it.

    3. Save the passphrase for future use in case the system needs to be recovered.

    4. Back up the key database for future use.

  6. Click Save to create the local tier and add it to your storage solution.
