 WARNING
DO NOT leave all assignments at None. This
indicates that no logical drives are accessible to
any port on any controller.
• The Set Sequential button sets all LUN assignments sequentially on all
available ports. This reproduces the default shown back in Figure 4-49
unless LUN Balancing is in effect.
• The Restore button resets the LUN Mapping assignments that are
currently saved in the configuration (the assignments in effect when the
LUN Mapping page was entered). This is handy if LUN assignments

Logical Drives, and LUN Mapping tabs.
• The Cancel button cancels the entire configuration, including what was
set up under the Disk Arrays, Logical Drives, and LUN Mapping tabs.
If you want to cancel only your LUN Mapping changes, use the
Restore button.
