Hitachi Vantara Qualified Professional – VSP Storage Architect — Question 44

You need to replace a broken fan in the Backup Module with Fan BKMF21 on a VSP E1090.

What is the correct procedure?

Answer options

• A. Use the MPC to remove the power from the backup module, and when the fan has stopped replace it.
• B. Go directly to the system and replace the faulty fan.
• C. Use the Maintenance Utility for stopping the fan, then replace it.
• D. Use Storage Navigator to put the Backup Module into replacement mode, then replace the fan.

Correct answer: D

Explanation

The correct answer is D because using Storage Navigator to put the Backup Module into replacement mode ensures that the system is properly prepared for the fan replacement. Option A is incorrect as simply removing power without proper procedures can cause issues, B is wrong because direct replacement without preparation can lead to system problems, and C does not ensure the module is in the correct state for replacement.
