The passphrase was entered incorrectly three times.

Action
  1. Reboot the server.
  2. Press the F9 key during POST to access the System Utilities.
  3. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Server Security > Device Encryption Options > Device Encryption Migration Options > Device Encryption Recovery Options.
  4. To unlock the HPE Persistent Memory modules using the exported file on a USB key, do the following:
    1. Connect the USB key.
    2. Select Restore Passphrases from USB Device.
    3. Enter the Transient Passphrase created when exporting the file.
    4. Choose Select File and browse to the location of the passphrase file on the USB key.
    5. Select Restore Encryption Settings to import the file.
  5. To unlock the HPE Persistent Memory modules for which the passphrases were manually recorded, do the following:
    1. Select Manually Unlock Devices.
    2. Select an HPE Persistent Memory module and enter the passphrase.
  6. If the passphrase for the HPE Persistent Memory module is unknown, and you are NOT required to retain or access any data stored on it, sanitize the HPE Persistent Memory module with the Cryptographic Erase option to reuse the module.

    This option does NOT allow you to retain or access any data previously stored on the HPE Persistent Memory module. It only allows you to regain use of the hardware.
