Answer

The deprioritized volumes can't be run the deduplication manually, but the prioritized volumes can.

 

Additional Information

The following error message shows if running deduplication manually for the deprioritized volume.

Failed to start efficiency on volume "Volume_Name" of Vserver "SVM_Name": Cannot perform efficiency operations on deprioritized volume. To be able to perform efficiency operations, run "volume efficiency promote" command first.(Error:40043)

You can determine the deprioritized volume as below. 

  1. Run command volume efficiency show.
  2. Check State column. The deprioritized volume's state is Disabled.

Example:

The volume testSLSource_dst is deprioritized volume, but the volume sis1 is not.

ontap93::> volume efficiency show
