The manager of a large distributed SAN wants to share the workload of daily administrative tasks between different storage administrators. Which two elements in Hitachi Device Manager can be used to…

Question

Options

• Ahost group
• Bresource group
• Cuser permissions
• Daccess control lists

• A
  17% (11)
• B
  73% (46)
• D
  10% (6)

Explanation

In Hitachi Device Manager (HDvM), resource groups (B) partition storage assets - volumes, ports, and pools - into logical subsets that can be assigned to specific administrators, effectively scoping their view to only the resources they manage. User permissions (C) then layer on top, defining what operations those admins can perform within their assigned resource groups. Together, these two elements control both what a storage admin can see and what they can do with it, enabling workload distribution across a team.

Host groups (A) are incorrect because they group initiators/hosts for LUN mapping purposes - they're a provisioning construct, not an administrative access-control mechanism. Access control lists (D) are a general security concept not used as a named element in HDvM's administrative model; HDvM relies on its own role/permission framework instead.

Memory tip: Think "R-U in control" - Resource groups define the scope, User permissions define the capability. You need both to properly delegate storage administration.
