Load the driver using one of the following methods:
To directly load the driver from the local build directory, issue the
following commands:
# insmod
/lib/modules/2.6.../kernel/drivers/scsi/scsi_transport_is
csi2.ko
# insmod qla4xxx.ko
To load the driver using modprobe, issue the following command:
# modprobe -v qla4xxx
2.
To load the qisioctl module using modprobe, issue the following command:
# modprobe -v qisioctl
3.
Start the iqlremote daemon by issuing the following command:
# 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, 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 command:
# service iqlremote stop
2.
Unload the qisioctl module, by issuing the following command:
# modprobe -r qisioctl
3.
To unload the driver using modprobe, issue the following command:
# modprobe -r qla4xxx
Rebuilding the RAM Disk with the New Driver

Where
X
is based on the order of the SCSI modules being loaded.
