A system administrator receives a monitoring alert for a server utilizing a software RAID 1 array. Diagnostics show that Drive 1 has developed critical S.M.A.R.T. read errors and has been flagged as degraded, while Drive 0 remains fully operational. Which of the following steps should the administrator take to restore full array functionality and redundancy without risking data loss? (Select TWO.)
- Fail and remove the degraded drive from the logical RAID array configuration using the management utility.Answer
- BRe-initialize and format the active RAID 1 array to clear the bad sectors on the impaired drive.
- Install a new drive of equal or greater capacity and rebuild the RAID 1 array using the healthy drive as the source.Answer
- DConvert the RAID 1 array into a RAID 0 array to bypass the bad sectors on the failing drive.
Answer
The correct actions are to logically fail and remove the degraded drive from the software RAID configuration, then install a replacement drive of equal or greater capacity and rebuild the array from the operational mirror drive.
When a RAID 1 array enters a degraded state due to drive corruption, proper recovery requires logically detaching the faulty disk using RAID management commands to prevent system instability, followed by installing a compatible replacement drive and initiating a rebuild sync from the surviving mirror disk.
