a. Change to the directory that contains the RAMDISK images.
# cd /boot
b. Create a backup copy of the RAMDISK (initrd) image.
# cp initrd-[kernel version].img initrd-[kernel
version].img.bak
c. Generate a new RAMDISK image containing the updated QLogic
FCoE driver.
# mkinitrd -f initrd-[kernel version].img `uname -r`
Depending on the server hardware, the RAMDISK file name may be
slightly different. The command is successful if there is no output.
d. Reboot the server for the new RAMDISK image to take affect:
# shutdown –r now
Instead of creating a new RAMDISK (Step 16), it may be possible (though
not recommended) to load the new driver without a reboot by unloading and
loading the driver using the modprobe utility:
1. To unload the driver using the modprobe utility, type the following
command:
# modprobe –r qla2xxx
The following error message indicates that the unload operation failed
because the server is engaged in I/O operations through the QLogic
adapter, or another module is dependent on the qla2xxx module.
FATAL: Module qla2xxx is in use
In this case, stop all I/O, eliminate dependent modules, and unload the
module again. Otherwise, you must create a new RAMDISK.
2. To load the driver using the modprobe utility, type the following
command:
# modprobe -v qla2xxx
The modprobe utility loads the qla2xxx.ko file in the directory
/lib/modules/2.6.<kernel-sub-version>/extra/qlgc-ql
a2xxx/. The following example message indicates that the load
operation was successful.
insmod/lib/modules/2.6.<kernel-sub-version>/extra/qlgc-ql
a2xxx/qla2xxx.ko
