Difficulty: EasyStorage Drives and RAID Array Issues

A technician is replacing a failed drive in a hot-swappable hardware RAID 5 server array. Place the steps in the correct order to complete the drive replacement and array recovery.

  1. 1Identify the failed hard drive bay using RAID management software or drive LED indicators.
  2. 2Remove the faulty drive from the hot-swap drive bay while the system remains powered on.
  3. 3Insert the replacement drive of equal or greater capacity into the vacant drive bay.
  4. 4Initiate or confirm the RAID array rebuild process using the controller utility.

Answer

The correct sequence for replacing a failed hot-swappable RAID 5 drive is: 1) Identify the failed drive bay using software or LEDs, 2) Remove the faulty drive from the bay, 3) Insert the replacement drive into the empty bay, and 4) Initiate or confirm the RAID array rebuild process.
The proper procedure begins by identifying the exact drive bay affected using LED status lights or system utilities. Next, the technician removes the failed drive using the hot-swap bay mechanism. Then, a fresh drive meeting capacity requirements is inserted. Finally, the technician monitors or triggers the RAID rebuild operation to calculate and restore missing data using parity from operational drives.

Step-by-Step Solution

1
Locate the failed drive using enclosure status LEDs or the controller software interface.
The specific physical bay containing the damaged disk is accurately identified.
Prevents accidentally removing a functional drive, which would cause array failure in a degraded state.
2
Safely disengage the latch and pull the failed drive out of the hot-swappable bay.
The failed disk is disconnected from the backplane while keeping server uptime.
Hot-swap architecture supports drive extraction without system power-down.
3
Slide the new disk of matching or higher capacity into the slot until fully seated.
The replacement disk connects to the RAID controller.
The controller requires a target disk with sufficient capacity to receive reconstructed parity data.
4
Verify through the RAID controller utility that the volume rebuild has started.
Parity calculations begin writing lost data onto the new drive, restoring total volume redundancy.
Ensures the storage volume transitions from degraded back to healthy status.
