You need to replace a failing power supply (PS) in a VSP E590. What is the correct procedure?

Question

Options

• ACheck if the status of the PS is blocked, and if yes, then replace it directly.
• BUse the Maintenance Utility for blocking the PS, then replace it.
• CUse the Maintenance Utility for blocking the controller, then replace the PS.
• DUse the MPC for blocking the PS, then replace it.

Explanation

On the VSP E590, the correct procedure requires using the MPC (Maintenance PC) to formally block the power supply before physically removing it - this ensures the system recognizes the component as offline and prevents data integrity issues or unexpected alerts during the swap.

Why the distractors are wrong:

• A is wrong because a "blocked" status alone does not mean you can replace it directly - you must actively initiate the block via the correct tool (MPC), not just observe the status.
• B is wrong because the Maintenance Utility is not the designated tool for this operation on the E590; the MPC is the correct interface for blocking hardware components like a PS.
• C is wrong on two levels: it targets the wrong tool (Maintenance Utility) and blocks the wrong component - you block the PS, not the controller, before a PS replacement.

Memory tip: Think "MPC = hardware, block first" - on VSP E-series systems, any hot-swap of a hardware unit (PS, drive, etc.) goes through the MPC, and you always block the specific component being replaced, never a parent component like the controller.
