When a system board is replaced, you must make sure that the TPM 2.0 firmware is updated to the latest 
version and the TPM policy is set correctly. 
CAUTION: 
Take special care when setting the TPM policy. If it is not set correctly, the system board can become 
unusable.
Update the TPM 2.0 firmware
When a system board is replaced, you must make sure that the TPM 2.0 firmware is updated to the latest 
version.
To update the TPM version: 
1.  Go to 
http://datacentersupport.lenovo.com and navigate to the support page for your server.
2.  Click Drivers & Software and download the latest version of BIOS/UEFI firmware.
3.  Update the firmware. See 
“Firmware updates” on page 7.
4.  Power on the system and press F1.
5.  If you have set the power on password, enter the correct password.
6.  Wait for about 90 seconds, the setup utilities window is displayed.
7.  Navigate to System Settings ➙ Security ➙ Trusted Platform Module and update the TPM.
8.  Reboot the system once the update is complete.
Set the TPM policy
By default, a replacement system board is shipped with the TPM policy set to undefined. You must modify 
this setting to match the setting that was in place for the system board that is being replaced.
There are two methods available to set the TPM policy: 
•  From Lenovo XClarity Provisioning Manager
To set the TPM policy from Lenovo XClarity Provisioning Manager: 
1.  Start the server and press the key according to the on-screen instructions to display the Lenovo 
XClarity Provisioning Manager interface.
2.  If the power-on Administrator password is required, enter the password.
3.  From the System Summary page, click Update VPD.
4.  Set the policy to one of the following settings. 
–  NationZ TPM 2.0 enabled - China only. Customers in the Chinese Mainland should choose this 
setting if a NationZ TPM 2.0 adapter is installed.
–  TPM enabled - ROW. Customers outside of the Chinese Mainland should choose this setting.
–  Permanently disabled. Customers in the Chinese Mainland should use this setting if no TPM 
adapter is installed.
Note: Although the setting undefined is available as a policy setting, it should not be used.
•  From Lenovo XClarity Essentials OneCLI
Note: Please note that a Local IPMI user and password must be setup in Lenovo XClarity Controller for 
remote accessing to the target system.
To set the TPM policy from Lenovo XClarity Essentials OneCLI: 
1.  Read TpmTcmPolicyLock to check whether the TPM_TCM_POLICY has been locked:
OneCli.exe config show imm.TpmTcmPolicyLock --override --imm <userid>:<password>@<ip_address>
