When you perform an "Add Subsystem" operation within Hitachi Device Manager (HDvM), you receive an error message. Which troubleshooting step would you perform first?

Question

Options

• ARestart HDvM.
• BCheck license status.
• COpen a case with HDS Support.
• DCheck the storage system for any inconsistent condition.

• A
  4% (2)
• B
  13% (7)
• C
  6% (3)
• D
  77% (40)

Explanation

When HDvM fails to add a subsystem, the root cause is almost always a problem with the storage system itself - an inconsistent condition (such as a partially configured volume, a failed component, or a conflicting configuration state) will prevent HDvM from successfully discovering or registering the device, making D the correct first step because it addresses the most likely source of the error directly.

Why the distractors are wrong:

• A (Restart HDvM) is a generic shotgun fix - it doesn't diagnose anything and wastes time if the storage system is the actual problem.
• B (Check license status) would be relevant if HDvM refused to run features entirely, not specifically on an "Add Subsystem" operation.
• C (Open a case with HDS Support) should only happen after you've exhausted local troubleshooting steps; escalating immediately is premature.

Memory tip: Think "storage first, software second, vendor last." For any operation that directly touches a storage subsystem, the storage system's own health is always the first suspect - HDvM is just the messenger.
