One of the few maintenance tasks often neglected by system
administrators, is that of upgrading server firmware. Whether that be
BIOS, Network cards, RAID or any other firmware, these subsystems might
never see an update during the life time of a server.
# wget -q -O – http://linux.dell.com/repo/hardware/latest/bootstrap.cgi | bash
# yum -y install firmware-tools.noarch
# yum -y install $(bootstrap_firmware)
# update_firmware --yes
# reboot
You might need to apply the last three steps a few times between reboots, as not all firmware is applied in the same go.
Also, you need to reboot your machine. No cold boot, shutdown, power off etc, just a nice warm reboot. :)
