A technician needs to replace two RAID controllers on a database server as part of an upgrade. The server has six external storage arrays and eight internal disks that are controlled by the two RAID controllers. The technician completes the replacement and powers the systems back on, but the server OS detects several missing disks in the configuration. Which of the following steps should the technician take first to resolve this issue?

A.

Reboot to the RAID controller BIOS and rescan for attached disks and arrays

Answers

Answers
C.

Turn off the external arrays and reboot the server to redetect the internal disks first

D.

Turn off all components and confirm all external and internal cables before rebooting

Answers
D.

Turn off all components and confirm all external and internal cables before rebooting

Suggested answer: A

Explanation:

When new RAID controllers are installed and disks go missing, the first logical step is to reboot to the RAID controller BIOS and rescan for attached disks and arrays (Answer A). This will allow the RAID controller to detect the connected drives and rebuild the RAID configuration as expected.

Rebooting to RAID controller BIOS (Answer A): This step ensures that all the attached disks and arrays are properly detected and mapped to the RAID configuration.

Checking UEFI settings (Option B): This might be useful later, but initially, the RAID controller BIOS should be checked first to verify disk detection.

Turning off external arrays (Option C): While this could be helpful in some scenarios, it's not the most efficient first step.

Checking cables (Option D): This could be necessary, but since the controllers were just replaced, software/BIOS configurations should be checked first.
