Answer

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

Additional Information

  • The following error message is generated when running deduplication manually on adeprioritized 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 vol4 has been deprioritized and the rest of the volumes have not . 

cluster1::> set diag; volume efficiency show -fields auto-state; set adm
vserver       volume auto-state
------------- ------ ----------
svm1_cluster1 vol1   Auto
svm1_cluster1 vol2   Auto
svm1_cluster1 vol3   Auto
svm1_cluster1 vol4   Deprioritized
