You have replaced a controller on a Hitachi Unified Storage system. Which two methods should be used to confirm that the replacement completed successfully? (Choose two.)

Question

Options

• ACheck the SNMP trap logs.
• BCheck the Alerts & Events window in SNM2.
• CCheck the Alerts & Events window in HCS.
• DCheck the status using the Web tool in Normal Mode.

Explanation

B and D are the correct answers.

After replacing a controller on a Hitachi Unified Storage (HUS) system, you should check the Alerts & Events window in SNM2 (Storage Navigator Modular 2), which is the native management GUI for HUS arrays - it will show whether any fault conditions have cleared and the replacement is recognized. You should also check the Web tool in Normal Mode, which provides direct hardware status feedback confirming the controller is online and functioning properly after maintenance.

Why the distractors are wrong:

• A (SNMP trap logs): SNMP traps are outbound alert notifications sent to external management systems - they're passive and not a reliable real-time verification method; you'd check them reactively, not as a post-maintenance confirmation.
• C (HCS): Hitachi Command Suite is the management platform for enterprise VSP-series arrays, not for Unified Storage (HUS) systems. HUS is managed via SNM2, not HCS.

Memory tip: Think "SNM2 = HUS, HCS = VSP" - match the tool to the platform. For HUS post-maintenance checks, you use SNM2 (software view) + the Web tool (hardware view) together - one confirms the software layer sees no alerts, the other confirms the hardware is in a normal operational state.
