Modifying FC Host Mapping 4
When a device has been mapped, it is still listed, though unavailable, in
the Internal LUN column.
In the following figure, the LUNs are not currently available for mapping
because they have already been mapped into the LUN/External LUN
column.
The device that was formerly found at assigned LUN 4 is now found at
assigned LUN 2. Drag it back into the Internal LUN column to make it
available for re-mapping. If you are working from the local touch screen,
select an external device LUN, and then select the right arrow.
