Zorluk: OrtaStorage Drives and RAID Array Issues

A storage administrator notices a warning notification on a database server utilizing a four-drive hardware RAID 10 array. The management console indicates that one SSD has failed due to excessive S.M.A.R.T. media errors, placing the array into a degraded state, though data remains fully accessible. Which TWO of the following steps should the administrator perform to restore full redundancy to the array without causing unnecessary downtime or data loss?

  1. Hot-swap the failed SSD with a spare drive of equal or greater capacity.Cevap
  2. B
    Reformat the entire RAID volume using OS disk management tools to clear file system corruption.
  3. Initiate a volume rebuild operation through the hardware RAID controller utility.Cevap
  4. D
    Convert the degraded RAID 10 array to a RAID 0 configuration to bypass the failed drive slot.

Cevap

The correct actions are to replace the failed drive using a hot-swap operation with an equivalent or larger capacity drive, and then initiate an array rebuild through the RAID controller interface.
When a single member disk in a RAID 10 configuration fails, the array operates in a degraded state because data redundancy is compromised for that mirrored pair. To restore redundancy safely without taking the server offline, the administrator should replace the faulty drive via hot-swapping and initiate a rebuild via the RAID controller utility to resynchronize mirrored block data.

Adım Adım Çözüm

1
Identify the specific drive slot reporting failure in the RAID controller interface and retrieve a compatible replacement disk.
Ensures the correct faulty disk is targeted and the replacement meets capacity requirements.
RAID rebuilds require replacement drives to be equal to or greater in capacity than the original disk.
2
Hot-swap the failed drive while maintaining power to the host server.
Physically replaces the non-functional hardware without service interruption.
Enterprise hardware RAID 10 controllers support online drive replacement.
3
Trigger or verify automatic execution of the array rebuild process using the RAID management console.
Copies mirrored parity/data onto the new drive, returning the array to an Optimal state.
Rebuilding restores redundancy so the volume can withstand future drive failures.
