Setting BIOS attributes using WinRM
You can set BIOS attributes using the SetBIOSAttributes method. The procedure is explained below using a task of enabling the
Trusted Platform Module (TPM) as an example.
NOTE: Ensure the TPM option is cleared in the BIOS before following the procedure to enable the TPM.
To set the BIOS attributes using WinRM commands:
1. Get the selector set by enumerating the DCIM_BIOSService class. Run:
winrm e wsman/DCIM_BIOSService?__cimnamespace=root/dcim/sysman -auth:basic -r:https://
<system IP or system name>:<Port Number (5985/5986)> -username:<user name> -
password:<password> -skipCAcheck -skipCNcheck -encoding:utf-8 -returnType:epr
NOTE: The selector set values (SystemName=<system name from DCIM_BIOSService class>winrm i SetBIOSAttributes
wsman/DCIM_BIOSService?SystemName=dt: +SystemCreationClassName=DCIM_ComputerSystem
+Name=DCIM:BiosService+CreationClassName=DCIM_BIOSService+) are used for set operation in this example.
2. Set the BIOS password on the system if not set already using the following command:
winrm i SetBIOSAttributes http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/
DCIM_BIOSService?__cimnamespace=root/dcim/sysman+Name=DCIM:BiosService
+SystemCreationClassName=DCIM_ComputerSystem+SystemName=<system name from
DCIM_BIOSService class>+CreationClassName=DCIM_BIOSService -r:https://<system IP or
system name>:5986 -u:<user name> -password:<password> -auth:basic -skipCAcheck -
skipCNcheck -encoding:utf-8 @{AttributeName="AdminPwd";AttributeValue="<Password>"}
3. Enable TPM security by running the following command:
winrm i SetBIOSAttributes "http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/
DCIM_BIOSService?__cimnamespace=root/dcim/sysman+Name=DCIM:BiosService
+SystemCreationClassName=DCIM_ComputerSystem+SystemName=<system name from
DCIM_BIOSService class>+CreationClassName=DCIM_BIOSService -r:https://<system IP or
system name>:5986 -u:<user name> -password:<password> -auth:basic -skipCAcheck -
skipCNcheck -encoding:utf-8 @{AttributeName="Trusted Platform
Module";AttributeValue="1";AuthorizationToken="<Admin password>"}
4. Restart the system.
5. Activate the TPM using the following command:
winrm i SetBIOSAttributes "http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/
DCIM_BIOSService?__cimnamespace=root/dcim/sysman+Name=DCIM:BiosService
+SystemCreationClassName=DCIM_ComputerSystem+SystemName=<system name from
DCIM_BIOSService class>+CreationClassName=DCIM_BIOSService -r:https://<system IP or
system name>:5986 -u:<user name> -password:<password> -auth:basic -skipCAcheck -
skipCNcheck -encoding:utf-8 @{AttributeName=("Trusted Platform Module
Activation");AttributeValue=("2");AuthorizationToken="<Admin password>"}
Setting BIOS attributes using WSMan
You can set BIOS attributes on the systems running Linux using the WSMan. The procedure is explained below using a task of
enabling the Trusted Platform Module (TPM) as an example.
NOTE: Ensure that the TPM option is cleared in the BIOS before following the procedure to enable the TPM.
1. Get the selector set by enumerating the DCIM_BIOSService class. Run:
wsman invoke –a “SetBIOSAttributes” http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/
DCIM_BIOSService?Name=”DCIM:BIOSService”,
SystemCreationClassName=”DCIM_ComputerSystem”, SystemName=”<system name from
DCIM_BIOSService class>”, CreationClassName=”DCIM_BIOSService” –N root/dcim/sysman –h
<system IP/name> –P 5985 –u <user name> –p <password> –y basic –v –V –k
“AttributeName=AdminPwd” –k “AttributeValue=<password>”
