ONTAP 7-Mode Transition

Compression is not enabled after transition from Data ONTAP 7.3.x


If you transition a 32-bit volume on a system running Data ONTAP 7.3.x to an ONTAP volume that is in a 64-bit aggregate, compression is not enabled on the ONTAP volume after the transition. Compression cannot be enabled until the volume is upgraded from 32-bit to 64-bit.


  1. Wait for the upgrade to finish.

    You can use the volume show -fields block-type -volume vol_name command to verify that the block type of the volume changes to 64-bit.

  2. Enable compression by using the volume efficiency modify command.
