How to erase disk data stored in E-series safely

[chenhui]

Hi Experts，

Starting with version 17.1, E-series SANtricity provides secure erasure of disk data. I want to know what the specific operation of this function is and how to safely erase data? Is there a difference in the way it is implemented compared to ONTAP's Sanitize function?

Many Thanks.

HI @chenhui ,

Ref - https://kb.netapp.com/on-prem/E-Series/Hardware-KBs/Is_there_a_way_to_sanitize_data_on_an_E_series_hard_disk_drive 

This is for non-FDE drives

• From SANtricity System Manager 11.71, a new sanitize (erase) capability is added for non-FDE drives.

You can refer to document (Page 12 onwards)- https://www.netapp.com/pdf.html?item=/media/17162-tr4474.pdf
