You need to know how much data is stored in the performance and cloud tiers for FabricPool. That information helps you determine whether you need to change the tiering policy of a volume, increase the FabricPool licensed usage limit, or increase the storage space of the cloud tier.

Steps

  1. Monitor the space utilization for FabricPool-enabled aggregates by using one of the following commands to display the information:

    If you want to display…​

    Then use this command:

    The used size of the cloud tier in an aggregate

    storage aggregate show with the -instance parameter

    Details of space utilization within an aggregate, including the object store's referenced capacity

    storage aggregate show-space with the -instance parameter

    Space utilization of the object stores that are attached to the aggregates, including how much license space is being used

    storage aggregate object-store show-space

    A list of volumes in an aggregate and the footprints of their data and metadata

    volume show-footprint

    In addition to using CLI commands, you can use Active IQ Unified Manager (formerly OnCommand Unified Manager), along with FabricPool Advisor, which is supported on ONTAP 9.4 and later clusters, or System Manager to monitor the space utilization.

    The following example shows ways of displaying space utilization and related information for FabricPool:

    cluster1::> storage aggregate show-space -instance

                          Aggregate: MyFabricPool
                                                                   ...
                                               Aggregate Display Name: MyFabricPool
                                                                   ...

                                                       Object Store Size: -

                                                 Logical Used Percentage: -
                                           Logical Unreferenced Capacity: -
                                         Logical Unreferenced Percentage: -
    cluster1::> storage aggregate show -instance

                           Aggregate: MyFabricPool
                           ...

                           Capacity Tier Used Size:

  2. Take one of the following actions as needed:

    If you want to…​

    Then…​

    Change the tiering policy of a volume

    Follow the procedure in Managing storage tiering by modifying a volume's tiering policy or tiering minimum cooling period.

    Increase the FabricPool licensed usage limit

    Increase the storage space of the cloud tier

    Contact the provider of the object store that you use for the cloud tier.
