Zorluk: OrtaStorage Drives and RAID Array Issues

A system administrator receives an automated alert indicating that a critical server hardware RAID 10 array has entered a degraded state due to a single hard drive failure. The server supports hot-swappable drive bays, and an identical replacement drive is available. Which of the following actions should the administrator take FIRST to restore full array redundancy?

  1. Replace the failed drive in its hot-swap bay and initiate an array rebuild through the RAID management controller.Cevap
  2. B
    Re-initialize the RAID 10 array configuration and perform a full system restore from the night's tape backup.
  3. C
    Format the degraded logical drive volume using the host operating system disk management utility.
  4. D
    Delete the existing RAID volume and reconfigure the remaining operational drives into a RAID 0 array.

Cevap

Replace the failed drive in its hot-swap bay and initiate an array rebuild through the RAID management controller.
When a single drive fails in a fault-tolerant RAID array (such as RAID 10), the array enters a degraded state but continues to function using mirrored data. The correct procedure is to hot-swap the failed drive with a new, compatible drive and allow the RAID controller to rebuild the array onto the replacement disk.

Adım Adım Çözüm

1
Identify the failed disk using RAID controller management software or drive bay LED indicators.
The exact failed physical drive location in the enclosure is confirmed.
Ensures the correct drive is targeted for hot-swapping without disturbing healthy array drives.
2
Remove the failed drive from the hot-swap bay and insert the replacement drive of equal or greater capacity.
The new drive is physically seated and recognized by the hardware RAID controller.
Hot-swappable backplanes allow drive replacement while the system remains powered on.
3
Initiate or confirm automatic rebuild of the replacement disk using the RAID management interface.
The RAID controller copies mirrored data back onto the new drive, restoring full redundancy.
RAID 10 uses mirrored pairs to reconstruct missing data onto the replacement disk.
