A field technician is servicing a dedicated rendering workstation configured with a hardware RAID 5 storage pool consisting of three 4 TB SATA hard drives. The system health console displays a degraded array alert, and the RAID controller management interface reports that Drive 2 has suffered a physical spindle failure and is offline. The client confirms that project files on the storage volume remain readable, though system performance has slowed significantly. Which of the following is the best immediate action the technician should take to restore full array redundancy?
- Hot-swap the failed drive with an operational disk of equal or greater capacity, then initiate a rebuild process in the RAID controller interface.Cevap
- BReformat the degraded volume within the host operating system disk management console to clear file system corruption before swapping the drive.
- CDelete the existing RAID 5 configuration matrix, replace the failed drive, recreate the logical array, and restore data from an offsite backup.
- DRemove all remaining functional drives from the workstation and test them individually on a separate system before replacing any hardware.
Cevap
The technician should hot-swap the failed drive with a new drive of equal or greater capacity, then initiate a rebuild process via the RAID controller utility.
In a RAID 5 configuration, parity information is distributed across all drives in the array. When one drive fails, the array enters a degraded state, but the data remains online and accessible. The standard procedural recovery requires replacing the failed physical disk with a healthy drive of equal or higher capacity and initiating a rebuild operation. The RAID controller uses the remaining drives' data and parity blocks to recalculate and write missing data onto the new disk, restoring full redundancy.
