A video editor reports severe performance degradation and occasional read timeouts when accessing archived media projects on a workstation. System diagnostics reveal that the workstation utilizes a software RAID 0 volume for scratch cache and a hardware RAID 10 array for long-term project storage. Controller logs show that a single disk in the hardware RAID 10 array has suffered a total mechanical failure and is offline, while all other physical drives report healthy status. Which of the following is the most appropriate immediate action for the technician to take to restore fault tolerance to the storage system?
- Replace the failed physical drive in the RAID 10 array and initiate an array rebuild operation.Cevap
- BRe-format the failed drive using disk management utilities and re-add it to the RAID 0 scratch cache volume.
- CDelete the RAID 10 array configuration and recreate it as a RAID 5 array using only the remaining operational drives.
- DBreak the RAID 10 volume mirror and convert the remaining online disks into independent unstriped dynamic disks.
Cevap
Replace the failed physical drive in the RAID 10 array and initiate an array rebuild operation.
Replacing the failed physical drive with a healthy disk of equal or greater capacity and starting a rebuild restores full redundancy to a RAID 10 array. Because RAID 10 relies on mirroring, the mirrored partner of the failed disk still holds an exact copy of the data, allowing the controller to reconstruct the mirror without data destruction.
