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

DVD.
For details about the failure, see the log files at <% systemdrive %>:\dell\suu
(on Microsoft Windows) and /var/log/dell/suu (on Linux systems).

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
