DUP Update of Firmware Might Fail While Running in the UEFI Mode
When Red Hat Enterprise Linux 6 or SLES 11 is installed and booted in a UEFI environment, flashing firmware using DUP might fail after DUP reboots the system.
DUP relies on a warm reset to enable firmware flashing. In the UEFI mode, the kernel by default performs a cold reset.
Boot the system with the reboot=k kernel command line option to enable the firmware flashing procedure to complete successfully. You could add this to /etc/grub.conf to be persistent across reboots.
