To load the driver using modprobe, issue the following command:
# modprobe -v qla4xxx
2. If the iqlremote agent was previously running, restart the agent by issuing
the following command (to ensure that the QConvergeConsole GUI can
reconnect to this host):
# service iqlremote start
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. To unload the driver, stop all applications
using the driver and then unload the driver.
1. If the iqlremote agent is running, stop the agent by issuing the following
command:
# service iqlremote stop
2. To unload the driver using modprobe, issue the following command:
# modprobe -r qla4xxx
Rebuilding the RAM Disk with the New Driver
1. Edit the /etc/modprobe.conf file and add the following entry (if it is not
present):
alias scsi_hostadapterX qla4xxx
Where X is based on the order of the SCSI modules being loaded.
2. To create a backup copy of the RAM disk image, issue the following
commands:
# cd /boot
# cp initrd-[kernel version].img initrd-[kernel
version].img.bak
3. Rebuild the initrd image by issuing the following commands:
# mkinitrd -f initrd-[kernel version].img `uname -r`
4. Reboot to boot from the new initrd image and new driver.
NOTE
Depending on the server hardware, the RAMDISK file name might be
different.
