Changing HPE Persistent Memory module passwords

IMPORTANT:

Be sure to observe all pop-up messages displayed in UEFI System Utilities that pertain to persistent memory. Failure to follow the instructions in these messages might cause persistent memory data loss.

Procedure
  1. During POST, press the F9 key to enter System Utilities.
  2. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Server Security > Device Encryption Options > Device Encryption Settings > Encrypted Devices.
  3. Choose the HPE Persistent Memory module from Select Device.
  4. Select Modify Passphrase from Select Operation.
  5. Choose the Passphrase Type:

    This selection is available only when Local Key Management is enabled. When Remote Key Management is enabled, HPE Persistent Memory module passwords are automatically generated, stored, and managed on the key management server.

    • Auto—The system automatically generates a 32 byte random password. Hewlett Packard Enterprise recommends using system-generated passwords as a best practice.

    • Manual—Enter a 32 byte password manually.

  6. Select Start Operation.

    The HPE Persistent Memory module password is changed.

  7. To change the password for each individual HPE Persistent Memory module, repeat the process.
  8. Hewlett Packard Enterprise recommends exporting the password database to a USB device for backup purposes:
    1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Server Security > Device Encryption Options > Device Encryption Migration Options > Device Encryption Export Options.
    2. Provide a password in the Transient Passphrase field.

      This password protects the exported file and must be entered when recovering the encrypted HPE Persistent Memory modules after relocation.

    3. Select Select File, and browse to a location on the USB key.
    4. Select Export Encryption Settings to create and export the file.
