Which three actions should be performed when replacing parts on a Hitachi Unified Storage system? (Choose three.)

Question

Options

• AUse a antistatic wrist wrap connected to the chassis.
• BPerform a firmware upgrade to the latest MGA level.
• CCollect and save a simple trace.
• DOpen a Clarify case with the HDS support center.
• EVerify the system status using Web tool.

Explanation

When replacing parts on a Hitachi Unified Storage (HUS) system, the three correct actions are A, C, and E.

Why these are correct:

• (A) Using an antistatic wrist wrap grounded to the chassis is mandatory ESD (Electrostatic Discharge) protection - static can permanently damage storage components.
• (C) Collecting and saving a simple trace captures the system's pre-maintenance state for diagnostics, giving HDS support a baseline if issues arise post-replacement.
• (E) Verifying system status via the Web tool confirms the system is in a known-good state before you begin and helps identify which component needs replacement.

Why the distractors are wrong:

• (B) A firmware upgrade to the latest MGA level is a separate maintenance activity - it is not a required step in a part replacement procedure and could introduce unintended changes.
• (D) Opening a Clarify case with HDS support is something you may do if you need assistance, but it is not a procedural requirement before swapping a part.

Memory tip: Think "Strap, Snap, Status" - strap on your antistatic wrap (A), snap a trace before you touch anything (C), and status-check the system with the Web tool (E). The other two options describe optional or separate activities, not core replacement steps.
