DUPs Fail on 64-bit Red Hat Enterprise Linux Operating System
If DUPs fail to run on a 64-bit Red Hat Enterprise Linux operating system,
manually install the following RPMs:
compat-libstdc++-33.i686
libstdc++-4.4.4-5.el6.i686
•libxml2.i686
NOTE: The RPMs are available on the RHEL 6 x64 media.
DUP Update of Firmware Might Fail While Running in the UEFI Mode
When RHEL6 or SLES11 is installed and booted in a UEFI environment,
flashing firmware via 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. A fix for this issue will be available
in a future update of the operating system.
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.
NOTE: Using the "reboot=w" option as documented in the Linux Kernel
Documentation might cause a Kernel Panic to occur on RHEL6 while the system
shuts down.
