Which three steps must be completed to enable secure access to LUs? (Choose three.)

Question

Options

• AMap LUs to the Host Group.
• BAdd host WWNs to the Host Group.
• CSet Multi-path Mode.
• DAdd Fibre Channel ports.
• EEnable Host Group security.

Explanation

Enabling secure LU access on Hitachi storage systems (e.g., VSP series) requires three coordinated steps: A (Map LUs to the Host Group), B (Add host WWNs to the Host Group), and E (Enable Host Group security). Together, these define which hosts are allowed (WWNs), what storage they can reach (LU mapping), and enforce the restriction (security enabled) - none of the three alone is sufficient.

Why the distractors are wrong:

• C (Set Multi-path Mode) controls how multiple I/O paths are balanced across ports for redundancy/performance - it has nothing to do with restricting access to LUs.
• D (Add Fibre Channel ports) is a physical infrastructure step (connecting HBAs or expanding port count) that must exist beforehand but is not part of the Host Group security configuration workflow.

Memory tip: Think of it as a guest list analogy - you must (1) write the guest names on the list (add WWNs), (2) assign them a table (map LUs), and (3) tell the bouncer to actually check the list (enable security). Skipping any one step means the security is either undefined, unassigned, or unenforced.
