Retaining the recovery key/password
About this task
The recovery key/password is generated during BitLocker setup, and can be saved and printed after
BitLocker is enabled. When using BitLocker, always retain the recovery key/password. The recovery key/
password is required to enter Recovery Mode after BitLocker detects a possible compromise of system
integrity.
To help ensure maximum security, observe the following guidelines when retaining the recovery key/
password:
• Always store the recovery key/password in multiple locations.
• Always store copies of the recovery key/password away from the node .
• Do not save the recovery key/password on the encrypted hard drive.
Enabling the Trusted Platform Module
1.
During the node startup sequence, press the
F9
key to access System Utilities.
2.
From the System Utilities screen, select

You can now enable TPM functionality in the OS, such as Microsoft Windows BitLocker or measured boot.
CAUTION:
When a TPM is installed and enabled on the node , data access is locked if you fail to follow the proper
procedures for updating the system or option firmware, replacing the system board, replacing a hard
drive, or modifying OS application TPM settings.
