I cannot update BIOS versions using SUU.
For systems with a TCG 1.2 compliant Trusted Platform Module (TPM) chip,
BIOS updates using SUU and DUPs fail if all of the following are true:
• The Microsoft Windows BitLocker Drive Encryption feature is enabled.
•The
Trusted Platform Module feature is set (using BIOS) to ON with
Pre-boot Measurement
. For information about TPM security settings,
see the
Dell OpenManage Server Administrator Online Help or the Dell
OpenManage Server Administrator User’s Guide
. This guide is available on
the Dell Support website at
support.dell.com/manuals .
For details about the failure, see the log files at <% systemdrive %>:\dell\suu
(on Microsoft Windows) and /var/log/dell/suu (on Linux systems).
To successfully update BIOS on such systems, perform the following steps:
1
Disable Microsoft Windows BitLocker Drive Encryption feature.
For information on disabling this feature, see the Microsoft
documentation at
www.microsoft.com .
2 Restart SUU and update BIOS.
3 Restart your system.
4 Re-enable the Windows BitLocker Drive Encryption feature.
For information on enabling this feature, see the Microsoft documentation
at

For details about TPM, see "Trusted Platform Module (TPM) and BitLocker
Support".
I cannot run SUU, the "SUU Logging System has failed: There is not
enough space on the disk" message is displayed.
While running SUU, ensure that the log directory specified at
<%
systemdrive %>:\dell\suu (on Windows operating systems) and
/var/log/dell/suu (on Linux operating systems) contains at least 10MB of
free space.
You can also specify a different directory to save the log files. See the SUU
command line options for more details.
