Note: The CCL (Command and Control LUN) is not used in most environments. This option is
recommended for host access 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.

Drive Selection Helper
If there are more than 10 drives in the partition, the drive selection helper appears (see
on the next page).
Drives in the partition can be batch selected by specifying the First Drive, Last Drive, and
Starting LUN Numbers. When a range of drives is selected, all other drives become unchecked
regardless of their current state.
Note: Generated LUN numbers are sequential and must stay in the 0 to 255 range.
