A network technician receives an automated notification indicating that a Network-Attached Storage (NAS) appliance configured with a four-drive RAID 10 array is operating in a degraded state. Diagnostics show that Drive 2 has experienced a complete mechanical hardware failure and is offline. Which of the following actions should the technician take to restore redundancy to the storage array while minimizing downtime? (Select TWO.)
- Replace the failed disk with a spare disk of equal or greater storage capacity.Cevap
- Initiate an array rebuild operation using the hardware RAID management console.Cevap
- CDelete the degraded array volume, reformat all member drives, and recreate the RAID 10 configuration.
- DForce the failed disk back online through the controller settings to clear the status alert.
Cevap
The technician should replace the failed disk with a spare disk of equal or greater capacity and initiate an array rebuild operation using the hardware RAID management console.
In a RAID 10 array, a single drive failure leaves the affected mirrored set degraded but functional. Restoring full redundancy requires physically swapping the failed disk with a functional drive of adequate size and starting an array rebuild via the RAID management interface so data from the surviving mirrored partner disk can be copied over.
