Can we convert ONTAP from DAR to NoDAR?
Applies to
- ONTAP 9
- NetApp Volume Encryption overview
- DAR (Data at rest)
Answer
Yes, but there are certain requirements that must be met
- You can upgrade an ONTAP image enabled for encryption (DAR) to a version of ONTAP that does not support encryption (NODAR) including the same major and minor versions.
- Before upgrading to an ONTAP version without NVE (NODAR) , your data volumes must be unencrypted.
- If you install a NODAR image with encrypted volumes your system will not boot up - Installation of ONTAP nodar (No Data At Rest Encryption) image fails
