If new hardware is not recognized, a reconfiguration boot might help. During the reconfiguration boot, the anaconda hardware configuration program is run with the –reconfig option.
To perform a reconfiguration boot, create an empty file called /etc/reconfigSys:
touch /etc/reconfigSys
and reboot the system.
