12 (Optional) Select the Use CCL check box to use the Command and
Control LUN.
Note: The CCL (Command and Control LUN) is not used in most

groups that contain an HP-UX host. It can also be used if
hosts that are not assigned to any host access group exist
in the SAN. The CCL is accessible to hosts only through LUN
0.
Caution: If you are not sure if you should use CCL, contact
Quantum Customer Support before you enable this
option.
