Configuring Driver Parameters Using modprobe

The modprobe Linux utility intelligently adds or removes a module from the Linux kernel, and is available with RHEL 5. Adapter driver parameter modifications that you make with modprobe require that you either reload the driver (nonpersistent change), or reboot the server (persistent change).

Reloading the QLogic FCoE driver (qla2xxx) for nonpersistent changes does not interrupt the adapter’s NIC function (qlge). Neither does reloading the QLogic NIC driver interrupt the FCoE function. Use modprobe to make nonpersistent changes only if the driver parameter cannot be changed using any other method.

Making Nonpersistent Changes Using modprobe

Nonpersistent changes are not preserved across server reboots. To make nonpersistent changes to adapter driver parameters using modprobe:

1.Unload the QLogic FCoE driver module. For example:

#modprobe –r qla2xxx
