After discovering a storage system with Hitachi Device Manager, which three categories are automatically displayed within the Volumes logical group? (Choose three.)

Question

Options

• AOpen - Allocated
• BOpen - Unallocated
• CMainframe - Allocated
• DMainframe - Unspecified
• EMainframe - Unallocated

• A
  87% (26)
• C
  10% (3)
• E
  3% (1)

Explanation

When Hitachi Device Manager (HDvM) discovers a storage system, it automatically populates the Volumes logical group with predefined subcategories. Open-system volumes are split into two clearly distinguishable states - Allocated (mapped to a host) and Unallocated (not yet assigned) - because HDvM can automatically detect their status. Mainframe volumes, however, appear as Unspecified (D) rather than Allocated or Unallocated, because HDvM cannot automatically determine mainframe volume allocation status during discovery without additional host configuration data.

Options C (Mainframe - Allocated) and E (Mainframe - Unallocated) are wrong because HDvM doesn't break mainframe volumes into those states automatically - it lumps them together under "Unspecified" until further information is available.

Memory tip: Think "Open volumes get clarity, Mainframe gets mystery." Open volumes are categorized clearly (Allocated/Unallocated), while Mainframe volumes are left as "Unspecified" - HDvM simply doesn't know enough about mainframe allocation at discovery time to split them further.
