Monitoring the space utilization for FabricPool

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.

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 Unified Manager for DM Series, which is supported on ONTAP 9.4 and later clusters, or ThinkSystem Storage Manager for DM Series 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 Unreclaimed Space Percentage: -
                          Object Store Size: -

cluster1::> storage aggregate show -instance

                           Aggregate: MyFabricPool
                           ...
                           Composite: true
                           Capacity Tier Used Size: 
                           ...

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	Contact your Lenovo or partner sales representative. Lenovo Data Center Support
Increase the storage space of the cloud tier	Contact the provider of the object store that you use for the cloud tier.
