A technician is servicing a business server containing two 2 TB SATA hard drives configured in a RAID 1 array. The system has become unresponsive during heavy write operations, and event logs reveal S.M.A.R.T. predictive failure alerts for Drive 1. Storage management software confirms the array is currently operating in a degraded state. Which of the following actions should the technician perform to safely resolve this issue? (Select TWO.)
- Back up all critical data from the operational drive to an external location prior to replacing hardware.Cevap
- Replace the failing drive with a new drive of equal or greater capacity and initiate an array rebuild.Cevap
- CReformat all drives in the current pool and recreate the RAID 1 volume from scratch.
- DConvert the degraded array into a RAID 0 striped volume to bypass mirror synchronization.
Cevap
The technician should back up critical data from the operational drive and replace the failing drive with one of equal or greater capacity to rebuild the RAID 1 volume.
When a RAID 1 mirror degrades due to a single drive S.M.A.R.T. hardware failure, data remains intact on the surviving operational drive. The correct procedure is to first ensure all data is safely backed up, then replace the failing disk with a drive of equal or greater capacity and execute a rebuild command to restore array redundancy.
