Drive Sanitization

Drive sanitization is a function that deletes data in a drive using the sanitization function of the
drives (SSDs, Online SAS disks, or Nearline SAS disks). The drive sanitization function can be used to
delete user data when, for example, discarding drives.
To use this function, the controller firmware version must be upgraded to V10L88 or later.
•
The Maintenance Operation policy is required to perform this function. Also, change the status
•
of the ETERNUS DX to the maintenance status.
To use this function, run "Sanitize Drive" from ETERNUS Web GUI.
•
• If the sanitization function is not supported by the drive, this function will terminate with an er-
ror.
