Erasing SED/ISE device data

NOTE:This operation is not supported when supported device is a part of a Virtual Disk. The target supported device must be removed from the virtual disk prior to performing device erase.

Cryptographic Erase permanently erases all data present on the disk. Performing a Cryptographic Erase on an SED/ISE overwrites all blocks and results in permanent loss of all data on the supported devices. During Cryptographic Erase, the host is unable to access the supported device. SED/ISE device erase can be performed either in real time or be applied after a system reboot.

If the system reboot or experiences a power loss during cryptographic erase, the operation is canceled. You must reboot the system and restart the process.

Before erasing SED/ISE device data, ensure that:
  • Lifecycle Controller is enabled.
  • You have Server Control and Login privileges.
  • Selected supported drive is not part of a virtual disk.
NOTE:
  • Erasing SED/ISE can be performed either as a real time or as a staged operation.
  • After the drive is erased, it may still be displayed as active within the OS due to data caching. If this occurs, reboot the OS and the erased drive will no longer be displayed or report any data.
  • Cryptographic erase operation is not supported for hot-plugged NVMe disks. Reboot the server before starting the operation. If the operation continues to fail, ensure that CSIOR is enabled and that the NVMe disks qualified by Dell Technologies.
  • Cryptographic erase can also be performed using PSID.
