Linux Driver Installation and Configuration: QLogic QME8242 Mezzanine Card User's Guide
Unloading the Adapter Driver
To replace an existing inbox driver with a new out-of-box iSCSI driver, unload the existing driver and load the new driver,
qisioctl module and iqlremote daemon. To unload the driver, stop all applications using the driver, and then unload the driver.
1. Stop the iqlremote daemon by issuing the following commands:
# service iqlremote stop
2. Unload the qisioctl module, using the modprobe command as follows:
# modprobe -r qisioctl
3. To unload the driver using modprobe, issue the following command:
# modprobe -r qla4xxx
Rebuilding the RAM Disk
To automatically load the driver by rebuilding the RAM disk to include the driver, follow these steps:
1. To create a backup copy of the RAM disk image, issue the following command:
# cd /boot
# cp initramfs-[kernel version].img initramfs-[kernel version].img.bak
2. Rebuild the initrd image with driver by issuing the following command:
# mkinitrd -f initramfs-[kernel version].img `uname -r`
3. Reboot the host to boot from the new initrd image with new driver.
NOTE: Depending on the server hardware, the RAMDISK file name may be different.
