Which of the following statements about LUN mapping on Dorado V6 is incorrect?

The correct answer is D. New LUNS can be directly mapped to a host or added to a LUN group (which has been mapped. Option D is incorrect because on Dorado V6, new LUNs cannot be directly mapped to a host as individual units - they must first be added to a LUN group, and it is the LUN group (not the individual LUN) that gets associated with a host through a mapping view.

Explanation

Option D is incorrect because on Dorado V6, new LUNs cannot be directly mapped to a host as individual units - they must first be added to a LUN group, and it is the LUN group (not the individual LUN) that gets associated with a host through a mapping view. The second half of option D ("added to a LUN group which has been mapped") is accurate, but the claim that a new LUN can be directly mapped to a host contradicts the architecture.

Why the distractors are correct (not the answer):

  • A is correct - LUN groups are the mapping unit, and they can be directly mapped to a host via a mapping view.
  • B is correct - a mapping view is mandatory; it ties together the host group, LUN group, and port group.
  • C is correct - the Dorado V6 UI allows creating LUNs or LUN groups directly from the host mapping page as a convenience shortcut.

Memory tip: Think of LUNs like passengers and LUN groups like buses - a passenger (LUN) can't pull up to a destination (host) alone; they must board a bus (LUN group) first, which then drives through the mapping view "gateway" to reach the host.
