by default are all part of the kernel rpm. If the drivers that were
deleted were part of the original installation then you'd need to
rpm -Uvh kernelfilename.rpm
which should replace any files that are part of the kernel rpm and were

reason, they, by default, load both the NIC and the iSCSI driver (for
QLogic initiators, I think the drivers are qla3xxx and qla4xxx).
The simple fix is to just remove the NIC driver from
/etc/modprobe.conf and rebuild the initrd, removing the NIC driver so
it doesn't load at boot time.
Essentially "yes", except on the QLogic drivers, we had to delete the
drivers, as removing them from modprobe.conf didn't suffice. Was a
couple of years ago, but this was far more challenging then what is
normally required to update drivers. We would get it working, remove it
from modprobe.conf, then upon reboot it would reinstall the NIC driver
at boot time.
I kept notes on it somewhere.
