A technician is assigned to service a desktop workstation whose hardware RAID 1 array is operating in a degraded state due to a drive fault. The system hardware does not support hot-swapping. What is the correct order of steps the technician should take to replace the faulty drive and restore full redundancy to the array?
- 1Identify the specific faulty physical drive slot using the RAID controller management software.
- 2Shut down the workstation completely and disconnect the power supply cable.
- 3Remove the failed drive from the internal bay and install a replacement drive of equal or greater capacity.
- 4Power on the system, enter the RAID controller utility, and assign the new drive to initiate the array rebuild.
- 5Monitor the array status in the management console until the rebuild finishes and status shows optimal.
Answer
The proper sequence to replace a non-hot-swappable drive in a degraded RAID 1 array is to first identify the faulty drive using the RAID management utility, shut down the system and disconnect power, swap out the bad drive for a healthy replacement, power on the system and configure the controller to begin the rebuild, and finally verify that the rebuild finishes with an optimal array status.
When dealing with a non-hot-swappable system, procedures must be strictly ordered to preserve data integrity and system safety. First, diagnose and identify the exact drive that failed within the array controller management tool. Second, perform a clean shutdown and power removal to enable safe hardware access. Third, physically replace the failed disk with a compatible replacement. Fourth, power on and access the RAID utility to add the new disk to the array and trigger the sync/rebuild process. Finally, verify that the rebuild operation completes and the array transitions back to an optimal status.
