  • ONTAP 9
  • NetApp Volume Encryption (NVE)
  • NetApp Aggregate Encryption (NAE)

Answer

1.  Set privilege level to advanced:

::> set adv

2.  Enable cross-volume-background-dedupe on all NAE volumes:

::*> volume efficiency modify -vserver <vserver_name> -volume <vol_name> -cross-volume-background-dedupe true

3.  Enable cross-volume-inline-dedupe on all NAE volumes:

::*> volume efficiency modify -vserver <vserver_name> -volume <vol_name> -cross-volume-inline-dedupe true

4.  Run volume-level background dedupe on all NAE volumes and wait for completion of all volumes:

::*> volume efficiency start -volume <vol_name> -vserver <vserver_name> -scan-old-data true -dedupe true

::*> volume efficiency show

5.  Run cross-volume background dedupe:

::*> storage aggregate efficiency cross-volume-dedupe start -aggregate <aggr_name> -scan-old-data true and storage aggregate efficiency cross-volume-dedupe show
