When re-purposing an Oracle Exadata Rack, it is typically a two-part process where you would first use the Secure Eraser feature introduced in Oracle Exadata System Software release 12.2.1.1.0 to securely erase the data first and then re-image the rack with the desired Oracle Exadata image.

Starting with Oracle Exadata System Software release 19.1.0, Secure Eraser is automatically started during re-imaging if the hardware supports Secure Eraser. This significantly simplifies the re-imaging procedure while maintaining performance. Now, when re-purposing a rack, you only have to image the rack and the secure data erasure is taken care of transparently as part of the process.

See Overview of Secure Erasure in Oracle Exadata Database Machine Security Guide for more information.

Minimum requirements:

• Oracle Exadata System Software release 19.1.0

• Oracle Exadata Database Machine X5-2 or later
