During a routine audit of a media editing workstation, the local RAID management utility reports that a four-disk hardware RAID 10 array is operating in a degraded state due to a single hard drive failure. The remaining three drives continue to function correctly and data remains accessible. Which action should be taken to restore array redundancy with minimal operational disruption and zero data loss?
- Replace the single failed drive with a healthy drive of equal or greater capacity and initiate an array rebuild through the RAID management software.Cevap
- BRe-initialize and format all remaining active drives in the controller, then restore the file system from a recent volume backup.
- CConvert the degraded RAID 10 array to a RAID 0 array within the controller utility to clear the warning status.
- DReplace all four hard drives simultaneously and recreate the RAID 10 volume configuration from scratch.
Cevap
Replace the single failed drive with a healthy drive of equal or greater capacity and initiate an array rebuild using the RAID management interface.
In a RAID 10 configuration, data is striped across mirrored disk pairs. When a single disk fails, its mirrored counterpart holds a full copy of the data, keeping the volume online in a degraded state. Replacing only the faulty disk and rebuilding the array restores fault tolerance without requiring data restoration from external backups or re-creating the array structure.
