Explanation

Before physically removing a failed drive on a VSP G700, you must click the Replace button in the Maintenance Utility (A) - this signals the controller to logically prepare for the swap, preventing data corruption or unexpected system behavior. You must also wear an ESD wrist strap (B), as electrostatic discharge can damage drive electronics and other sensitive components in the enclosure.

Option C is wrong because the red LED indicates a drive has already failed, but its illumination is a symptom to help you locate the drive - not a required prerequisite before starting the procedure. Option D is wrong because VSP G700 drives are hot-swappable; powering down the Drive Box is unnecessary and would cause unnecessary downtime on an enterprise system designed for continuous availability.

Memory tip: Think "Software first, then Safety" - trigger the Replace button in software (A) before you touch anything, and always protect hardware with ESD gear (B). Any answer suggesting you power down an enterprise array or wait for an LED is a red flag.
