      Those only work if the driver is not native. The native ones included
      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
      simply :

      rpm -Uvh kernelfilename.rpm

      which should replace any files that are part of the kernel rpm and were deleted.

      I think that's probably solaris...

      Are you sure that RH wasn't just loading BOTH drivers? For some
      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.
