A technician is troubleshooting a RAID 6 array on a high end CAD/CAM workstation. Two disk drives have their fault lights on. Which of the following is the BEST action for the technician to perform when fixing this problem?

Question

Accepted Answer

A. Replace the failed drives and verify the RAID rebuilds completely. RAID 6 uses dual distributed parity, meaning it can sustain exactly two simultaneous drive failures while keeping data intact and accessible. With two fault lights active but no additional failures, the data is still recoverable through the parity information on the remaining drives - replacing the failed drives and verifying the RAID controller rebuilds the array is the correct and complete remediation.

Answer

B. Reseat the drives, backup the data, and then replace them. Reseating the drives is inappropriate when fault lights confirm actual drive failure; reseating delays proper remediation and does not address failed hardware.

Answer

C. Reseat the drives and monitor the RAID status over a few days. Monitoring over several days is dangerous because RAID 6 with two failed drives has zero remaining fault tolerance - any additional failure during that period would cause total data loss.

Answer

D. Replace the failed drives and restore the data from a known good backup. Restoring from backup is unnecessary since RAID 6 still holds intact data on the surviving drives; a full restore would be slower and riskier than a standard RAID rebuild.
