A desktop workstation hosting a local database experiences severe performance degradation and intermittent file read errors. Upon checking the storage management console, the technician notes that the two-disk hardware RAID 1 array is marked as Degraded, with Disk 1 reporting multiple uncorrectable S.M.A.R.T. read sector errors. The surviving drive, Disk 0, is reported as healthy and online. Which of the following is the most appropriate immediate action for the technician to take to restore full array redundancy?
- Replace Disk 1 with a new disk of equal or greater capacity and initiate an array rebuild through the RAID management controller.Cevap
- BBack up the stored data, delete the existing array, perform a full format on both drives, and recreate the RAID 1 volume.
- CConvert the degraded RAID 1 array to a RAID 0 configuration to bypass the failing drive while maintaining volume access.
- DRun a system file check and disk surface repair utility on Disk 1 to fix bad sectors before resuming normal operation.
Cevap
Replace Disk 1 with a new disk of equal or greater capacity and initiate an array rebuild through the RAID management controller.
In a RAID 1 (mirroring) setup, a single drive failure leaves the volume functioning in a degraded state using the remaining healthy disk. The standard recovery procedure is replacing the failed drive with a new disk of equal or greater capacity and rebuilding the array via the RAID controller interface.
