If all volumes are unallocated from a host, which two dialog options are available using Hitachi Device Manager? (Choose two.)

Question

Options

• AReturn Capacity to Pool
• BDelete Volume
• CShred Volume
• DDelete Host Group

• A
  3% (1)
• B
  93% (28)
• C
  3% (1)

Explanation

When all volumes are unallocated from a host in Hitachi Device Manager, the system unlocks two lifecycle management options: Delete Volume (B) removes the volume entirely from the storage array, and Delete Host Group (D) removes the host group definition since no volumes remain attached to it - both actions become safe only after full unallocation.

Why the distractors are wrong:

• A (Return Capacity to Pool) is only applicable to thin-provisioned volumes whose capacity was drawn from a Dynamic Pool; it doesn't apply universally to all volume types.
• C (Shred Volume) is not a standard Hitachi Device Manager dialog option in this context - data shredding/sanitization is handled through separate secure erase workflows, not through the standard unallocation flow.

Memory tip: Think of the two actions as "clean up the data container and clean up the host record" - once a host has nothing attached, you can Delete both the Volume (the storage object) and the Host Group (the access definition). The word "Delete" appearing in both correct answers is your anchor.
