Data Deduplication Commands missing

I am trying to disable Data Deduplication on Windows Server 2012 R2.  When I try to run any of the deduplication commands in Powershell I get the term disable-dedupvolume is not recognized as the name of a cmdlet message.  I get the same message no matter which dedup command I try to run.  I tried running Import-Module Deduplication but that results in no valid module file was found.

 

I have also tried upgrading PowerShell from 4.0 to 5.1.

 

Can someone tell me where I can get these commands from?

 

Thanks in advance.

    Hi dannetsphere 

     

    The commands should be available in once the DeDuplication feature is installed on the server; if you run the below does it show up as installed?

     

    Get-WindowsFeature -Name FS-Data-Deduplication

     

    In addition, can you see the deduplication settings via Server Manager (assuming this isn't a core installation of 2012R2?

      Hi HidMov

      I ran the command you provided and it did say the feature was installed.  I was able to copy the files from another server so I'm good now.

      There wasn't much info in the Server Manager

      Thanks for the reply
