Get-NaEfficiency (TotalLunSize and OverProvisioningPercent) commands aren't working properly

Hi all ,

Get-NaEfficiency (TotalLunSize and OverProvisioningPercent) commands aren't working properly

vol1 : 100g (thin)

vol2 : 100g (thick)

lun1 : /vol/vol1/lun1 , 150g(thin)

lun2 : /vol/vol2/lun1 , 50g(thick)

(Get-NaEfficiency vol1).TotalLunSize is "0"

(Get-NaEfficiency vol1).OverProvisioningPercent is "0"

(Get-NaEfficiency vol2).TotalLunSize is "0"

(Get-NaEfficiency vol2).OverProvisioningPercent is "0"

TotalLunSize: Total size of all the LUNs contained within this volume. This value is only valid when the -Recurse switch is present.

OverProvisioningPercent: The LUN over-provisioning percent of the volume. This value is equal to (TotalLunSize / Capacity) * 100. This value is only valid when the -Recurse switch is present.

But it must be different value.

do you have any idea ?

You'll need to use the "-Recurse" switch for those values to be populated:

(Get-NaEfficiency vol1 -Recurse).TotalLunSize
(Get-NaEfficiency vol2 -Recurse).TotalLunSize
