[-over-provisioned {<integer>[KB|MB|GB|TB|PB]}] - Over Provisioned Size
If this parameter is specified, the command displays information only about the volume or volumes that have the specified size not available in the aggregate. This applies only for a 'none' guaranteed volume when it's unused size exceeds available space in the aggregate. This value is always zero for 'volume' guaranteed volumes.
[-snapshot-reserve-available {<integer>[KB|MB|GB|TB|PB]}] - Available Snapshot Reserve Size
If this parameter is specified, the command displays information only about the volume or volumes that have the specified size available for Snapshot copies within the Snapshot reserve. This value is zero if Snapshot spill is present. For 'none' guaranteed volumes, this may get reduced due to less available space in the aggregate.
[-logical-used {<integer>[KB|MB|GB|TB|PB]}] - Logical Used Size
If this parameter is specified, the command displays information only about the volume or volumes that have the specified logical used size. This value includes all the space saved by the storage efficiency features along with the physically used space. This does not include Snapshot reserve but does consider Snapshot spill.
[-logical-used-percent <percent_no_limit>] - Logical Used Percentage
If this parameter is specified, the command displays information only about the volume or volumes that have the specified logical used percentage.
[-logical-available {<integer>[KB|MB|GB|TB|PB]}] - Logical Available Size

This value is the amount of free space currently available considering space saved by the storage efficiency features as being used. This does not include Snapshot reserve.
[-logical-used-by-afs {<integer>[KB|MB|GB|TB|PB]}] - Logical Size Used by Active Filesystem
If this parameter is specified, the command displays information only about the volume or volumes that have the specified logical size used by the active file system. This value differs from logical-used by the amount of Snapshot spill that exceeds Snapshot reserve. This parameter is not supported on FlexGroups.
[-logical-used-by-snapshots {<integer>[KB|MB|GB|TB|PB]}] - Logical Size Used by All Snapshots
If this parameter is specified, the command displays information only about the volume or volumes that have the specified logical size used across all Snapshot copies. This value differs from size-used-by-snapshots by the space saved by the storage efficiency features across the Snapshot copies. This parameter is not supported on FlexGroups.
[-is-space-reporting-logical {true|false}] - Logical Space Reporting
If this parameter is specified, the command displays information only about the volumes that have logical space reporting enabled or disabled as specified. When space is reported logically, ONTAP reports the volume space such that all the physical space saved by the storage efficiency features are also as reported as used. This parameter is not supported on FlexGroups.
[-is-space-enforcement-logical {true|false}] - Logical Space Enforcement
If this parameter is specified, the command displays information only about the volumes that have logical space enforcement enabled or disabled as specified. When space is enforced logically, ONTAP enforces volume settings such that all the physical space saved by the storage efficiency features will be calculated as used. This parameter is not supported on FlexGroups.
[-tiering-policy {snapshot-only|auto|none|backup}] - Volume Tiering Policy
If this parameter is specified, the command displays information only about the volumes whose tiering policy matches the specified value. Tiering policies determine whether the user data blocks of a volume in a FabricPool will be tiered to the capacity tier when they become cold. FabricPool combines flash (performance tier) with an object store (external capacity tier) into a single aggregate. Temperature of a volume block increases if it is accessed frequently and decreases when it is not.
The available tiering-policies are:
  • snapshot-only - This policy allows tiering of only the volume Snapshot copies not associated with the active file system.
  • auto - This policy allows tiering of both snapshot and active file system user data to the capacity tier.
  • none - Volume blocks will not be tiered to the capacity tier.
  • backup - On DP volumes this policy allows all transferred user data blocks to start in the capacity tier.
[-tiering-minimum-cooling-days <integer>] - Volume Tiering Minimum Cooling Days (privilege: advanced)
This parameter displays the minimum number of days that user data blocks of the volume must be cooled before they can be considered cold and tiered out to the capacity tier. If a value is not displayed then the system default is still being used and has not been overridden with this option. The default minimum cooling period for snapshot-only policy is 2 days and for auto policy is 31 days.
[-performance-tier-inactive-user-data {<integer>[KB|MB|GB|TB|PB]}] - Performance Tier Inactive User Data
If this parameter is specified, the command displays the amount of inactive user data stored in the performance tier that could be tiered out to a capacity tier if the volume is in a FabricPool and has the auto tiering policy. For more information see the tiering-policy parameter.
[-performance-tier-inactive-user-data-percent <percent>] - Performance Tier Inactive User Data Percent
If this parameter is specified, the command displays the percentage of inactive user data in the performance tier.
