Volume Information:
-Aggregate:  Must reside on an AFF model.  Available in all ONTAP versions that support that AFF model.
-Thin Provisioned: Volume space guarantee set to none and the space guarantee is enabled.  Available in all ONTAP versions.
-Encryption at Aggregate Level or Off: Either encryption is disabled or if enabled the volume is set to aggregate encryption-type.  Available in ONTAP 9.6 and newer.
-Efficiency Enabled:  Volume efficiency is on.  Available in all ONTAP versions.
-Data Compaction Enabled:  Available in all ONTAP versions.
-Compression Enabled:  Available in all ONTAP versions.
-Inline Compression Enabled:  Available in all ONTAP versions.
-Inline Dedupe Enabled:  Available in all ONTAP versions.
-Cross Volume Background Dedupe Enabled: Available in ONTAP 9.3 and newer.
-Cross Volume Inline Dedupe Enabled:  Available in ONTAP 9.3 and newer.
-Schedule Blank:  The volume efficiency schedule is set to "-".  Corresponds to the policy being set to auto.  Available in ONTAP 9.3 and newer.
-Auto Policy:  The volume efficiency policy is set to "auto".  Available in ONTAP 9.3 and newer.
-Adaptive Compression Type:  The volume efficiency compression-type is set to adaptive.  Available in all ONTAP versions.
-Is Prioritized:  The volume has not been deprioritized with the auto policy configuration.  Available in ONTAP 9.3 and newer.

Aggregate Information:
-Name: The name of the aggregate
-Node: The node where the aggregate resides
-Aggregate Data Reduction Storage Efficiency Ratio:  Displays the storage efficiency ratio of the aggregate
-Volume Data Reduction Storage Efficiency Ratio:  Displays the storage efficiency ratio of all the volumes in the aggregate
-Total Data Reduction Storage Efficiency Ratio:  Displays the total storage efficiency ratio of the aggregate
-Used Space in TiB:  Actual used space measured in TiB
-Total Space in TiB:  Total space of aggregate measured in TiB
-Effective Capacity of Used Space Multiplied by Total Data Reduction SE Ratio in TiB:  The "Used Space in TiB" multiplied by the first number in the "Total Data Reduction Storage Efficiency Ratio" field.
