Making Nonpersistent Changes to the QLogic NIC Driver
Parameters To make changes that are not persistent across reboots, use the
modprobe command to specify the driver parameters and their values. For
example:
1. Unload the QLogic FCoE driver module:
# modprobe -r qlge
2. Load the QLogic NIC driver module specifying the driver parameters to be
changed. One or more parameters can be specified separated by a space.
For example, the following command enables MSI interrupts and specifies
that memory not be allocated for the MPI firmware dump:
# modprobe -v qlge qlge_irq_type =1 qlge_mpi_coredump=0
3. Verify that the values for these parameters have changed. For example:
# cat /etc/bus/pci/drivers/qlge/module/parameters/
qlge/qlge_irq_type
# cat /etc/bus/pci/drivers/qlge/module/parameters/
qlge/mpi_coredump
Making Persistent Changes to the QLogic NIC Driver To make changes
that are persistent across reboots, edit the file /etc/modprobe.conf, add the
QLogic NIC driver parameters with their values, build a new RAMDISK image and
reboot. For example:
1. Open the file /etc/modprobe.conf in read/write mode using a Linux
editor.
#vi /etc/modprobe.conf
NOTE:
Reloading the QLogic NIC driver (qlge) does not interrupt the QLogic
adapter FCoE function (qla2xxx). Neither does reloading the QLogic
FCoE driver interrupt the NIC function.
For nonpersistent changes, use modprobe only if the driver parameter
cannot be changed using any other method
