Get-NaEfficiency to show list of volumes with snapshots over 20g

jasonpadman — Thu, 05 Jun 2025 06:24:25 GMT

Hello good people,

I'm very new to powershell and was hoping someone could help me work out how I can filter the results of the Get-NaEfficiency cmdlet so that it only show the volumes with snapshot size over 20gb. I have tried using the below but with no luck"

Get-NaEfficiency | where {$_.SnapUsage -gt 20000}

Any help would be much appreciated.

Get-Member is your friend:

PS C:\> Get-NaEfficiency | gm

TypeName: DataONTAP.PowerShell.SDK.Cmdlets.Toolkit.Efficiency.VolEfficiencyInfo

Name MemberType Definition

---- ---------- ----------

Equals Method bool Equals(System.Object obj)

GetHashCode Method int GetHashCode()

GetType Method type GetType()

ToString Method string ToString()

Allocated Property System.Decimal Allocated {get;set;}

Capacity Property System.Decimal Capacity {get;set;}

Children Property System.Collections.Generic.Dictionary`2[[System.String, mscorlib, Version=2.0.0.0...

EffectiveUsed Property System.Decimal EffectiveUsed {get;set;}

EfficiencyPercentage Property System.Int32 EfficiencyPercentage {get;set;}

Free Property System.Decimal Free {get;set;}

Name Property System.String Name {get;set;}

OverProvisioningPercent Property System.Decimal OverProvisioningPercent {get;set;}

PhysicalUsed Property System.Decimal PhysicalUsed {get;set;}

QuotaCommitted Property System.Decimal QuotaCommitted {get;set;}

QuotaOvercommit Property System.Decimal QuotaOvercommit {get;set;}

QuotaUsed Property System.Decimal QuotaUsed {get;set;}

Reserve Property System.Decimal Reserve {get;set;}

ReserveUsed Property System.Decimal ReserveUsed {get;set;}

Returns Property DataONTAP.PowerShell.SDK.Cmdlets.Toolkit.Efficiency.ReturnsInfo Returns {get;set;}

SnapUsage Property DataONTAP.PowerShell.SDK.Cmdlets.Toolkit.Efficiency.SnapshotUsageInfo SnapUsage {...

SpaceReserve Property System.String SpaceReserve {get;set;}

TotalLunSize Property System.Decimal TotalLunSize {get;set;}

TotalSize Property System.Decimal TotalSize {get;set;}

Used Property System.Decimal Used {get;set;}

So then dig into SnapUsage:

PS C:\> (Get-NaEfficiency testvol3).SnapUsage | gm

TypeName: DataONTAP.PowerShell.SDK.Cmdlets.Toolkit.Efficiency.SnapshotUsageInfo

Name MemberType Definition

---- ---------- ----------

Equals Method bool Equals(System.Object obj)

GetHashCode Method int GetHashCode()

GetType Method type GetType()

ToString Method string ToString()

Count Property System.Int32 Count {get;set;}

Overflow Property System.Decimal Overflow {get;set;}

Reserve Property System.Decimal Reserve {get;set;}

Used Property System.Decimal Used {get;set;}

So then we can use:

PS C:\> Get-NaEfficiency testvol3 | where { $_.SnapUsage.Used -gt 20000 } | ft -AutoSize

Name Capacity Used Free SnapUsage Reserve Returns EfficiencyPercentage

---- -------- ---- ---- --------- ------- ------- --------------------

testvol3 16.0 GB 556.3 MB 15.5 GB 5.6 MB 0 556.0 MB 6%
