You want to configure hosts connected to a VSP using the Host Scan feature of Hitachi Device Manager. Which action must be performed?

Question

Options

• BEnsure all hosts are related to the same host group.
• CSet the storage WWN for LUN security.
• DSet the host WWN for LUN security.

• A

• B
  2% (1)
• C
  2% (1)
• D
  4% (2)

Explanation

For Hitachi Device Manager's Host Scan feature to discover and configure hosts connected to a VSP, each host must be associated with a host group - this is the prerequisite that allows Device Manager to recognize and manage the host-to-storage relationships during scanning.

Why the distractors are wrong:

• B is too restrictive - hosts do not need to share the same host group; they simply each need to belong to some host group.
• C is incorrect because LUN security uses the host WWN (not the storage WWN) to control access.
• D involves LUN security configuration, which is a separate concern from enabling Host Scan discovery - it's not a prerequisite for the scan itself.

Memory tip: Think "A host needs A group" - the indefinite article "a" in option A is your clue that any host group association works, unlike option B's "same" which implies an unnecessary restriction.
