To Load the Newly Built Fibre Channel Driver

After you build the fibre channel driver, as described in To Build the Fibre Channel Driver , you can choose to manually or automatically load the driver. This section contains the following topics:

• To Manually Load the Fibre Channel Driver

• To Automatically Load the Fibre Channel Driver

To Manually Load the Fibre Channel Driver

After building the fibre channel driver, you can choose to manually load the driver. If you want to automatically load the driver, skip to To Automatically Load the Fibre Channel Driver.

1. Build the driver binary, as described in To Build the Fibre Channel Driver .
2. Manually load the driver by using the modprobe -v command.

   # modprobe -v qla2xxx
   

3. If you want to manually unload the driver, use the modprobe -r command.

   # modprobe -r qla2xxx
   # modprobe -r qla2xxx_conf (SANsurfer use only)
   

To Automatically Load the Fibre Channel Driver

After building the fibre channel driver, you can choose to automatically load the driver. If you want to manually load the fibre channel driver, see To Manually Load the Fibre Channel Driver.

1. Build the driver binary, as described in To Build the Fibre Channel Driver .
2. Install the driver module (*.ko) files to the appropriate kernel module directory.

   # ./extras/build.sh install
   

3. For Red Hat Linux users, edit the /etc/modprobe.conf file and add the following entries, if they are not present:
   • alias scsi_hostadapter1 qla2xxx_conf (for use only with SANsurfer)
   • alias scsi_hostadapter2 qla2xxx
4. For SUSE Linux users, edit the /etc/sysconfig/kernel file and modify the INITRD_MODULES directive as shown in the following example.

   In this example, note that you must add the first module, qla2xxx_conf (for SANsurfer), followed by the qla2xxx module. The qla2xxx_conf module is for use only with SANsurfer while the qla2xxx module is a common module.

    ...
   INITRD_MODULES=".... qla2xxx_conf qla2xxx"
   ...
   

5. Change to the /boot directory.
6. Back up the current RAMDISK image.

   # cp -f initrd-2.6.kernel-version.img initrd-2.6.kernel-version.img.bak
   

7. Build the RAMDISK image with the mkinitrd -f command.

   Red Hat: # mkinitrd -f initrd-2.6.kernel-version.img kernel-version
   SUSE: # /sbin/mk_initrd
   

8. Reboot the system to load the RAMDISK image with the driver.
