Retaining the recovery key/password
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 server.
•
Do not save the recovery key/password on the encrypted hard drive.
Enabling the Trusted Platform Module

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 server, 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.
