Sanitize/Erase NVMe device

Select this function to remove and destroy all data from the NVMe media and the cache.

There are five types of sanitize:
User data secure erase
All user data is erased. The content of the user data after the erase is indeterminate (For example, the user data might be zero filled, one filled, etc.). The controller might perform a cryptographic erase when a User Data Erase is requested if all user data is encrypted.
Format cryptographic erase
All user data is erased cryptographically. This is accomplished by deleting the encryption key.
Sanitize overwrite
User data is altered by writing a fixed data pattern or related patterns to all locations on the media within the NVMe subsystem in which user data may be stored one or more times.
Sanitize block erase
User data is altered with a low-level block erase method that is specific to the media for all locations on the media within the NVMe subsystem in which user data may be stored.
Sanitize cryptographic erase
User data is altered by changing the media encryption keys for all locations on the media within the NVMe subsystem in which user data may be stored.
Notes:
  • Each type of NVMe device might implement only a subset of the Sanitize functions described above.
  • The sanitize function destroys all data in the namespaces which exist on the selected NVMe device.
  • The sanitize function is available only for NVMe devices that only contain namespaces which represent non-configured disk units (disk units which do not belong to an auxiliary storage pool).
  1. On the Use System Service Tools (SST) display, select Work with disk units.
  2. On the Work with Disk Units display, select Work with disk configuration.
  3. On the Work with Disk Configuration display, select Work with NVMe Devices.
  4. On the Work with NVMe Devices display, select Sanitize/Erase NVMe device.
  5. On the Select NVMe Device display, select the NVMe device.
  6. On the Select Type of Sanitize display, select the type of sanitize function that you want to perform.
  7. On the Confirm Sanitize/Erase NVMe Device display, press F10 to confirm your selection.
