ONTAP Powershell tookit error


I did the following with Powershell, but it doesn't seem to work properly on the Stripe volume. Is it correct to work with Stripe volume?

PS C:\Program Files (x86)\NetApp\NetApp PowerShell Toolkit\Modules> get-nahostdisk

Hello Parksangil,


At this time "InvokeNaHostVolumeSpaceReclaim" does not support striped volumes. Starting with Windows 2012 and later, SCSI Unmap is in-band and automatic, thus running Space Reclamation is no longer necessary.


This KB provides more details:

Thank you for reply.

The OS I am using is windows 2008.
Is there any other way to reclaim on stripe volume?
