Zorluk: OrtaStorage Drives and RAID Array Issues

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.)

  1. Replace the failed disk with a spare disk of equal or greater storage capacity.Cevap
  2. Initiate an array rebuild operation using the hardware RAID management console.Cevap
  3. C
    Delete the degraded array volume, reformat all member drives, and recreate the RAID 10 configuration.
  4. D
    Force 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.

Adım Adım Çözüm

1
Obtain a compatible replacement drive.
A disk with identical or greater capacity is acquired.
RAID controllers require replacement drives to be at least as large as the failed member disk to rebuild mirrored blocks.
2
Hot-swap the failed drive with the replacement drive.
The degraded bay receives the new operational disk.
Physical replacement restores hardware availability for the mirrored drive pair.
3
Start or verify the array rebuild process.
The controller mirrors active data to the replacement disk, returning the array status to Optimal.
Rebuilding synchronizes the newly inserted drive with its paired surviving disk.
