A technician receives an alert that one hard drive in a hot-swappable RAID 1 array has failed, causing the array to run in a degraded state. What is the correct sequence of steps the technician should take to restore full redundancy to the RAID array?
- 1Identify the failed physical drive using enclosure LEDs or RAID management software.
- 2Release the carrier latch and remove the failed drive from the hot-swap drive bay.
- 3Insert a new replacement drive of equal or greater capacity into the hot-swap bay.
- 4Verify that the RAID controller initiates the array rebuild process to restore fault tolerance.
Answer
The correct order of operations is: 1) Identify the failed physical drive using enclosure LEDs or RAID management software, 2) Release the carrier latch and remove the failed drive from the hot-swap drive bay, 3) Insert a new replacement drive of equal or greater capacity into the hot-swap bay, and 4) Verify that the RAID controller initiates the array rebuild process to restore fault tolerance.
The standard procedure for replacing a failed hot-swappable drive in a degraded RAID array begins with identifying the specific failed drive using status LEDs or management utility software. Next, the technician disengages and removes the faulty drive from its slot. A new replacement disk of sufficient capacity is then inserted into the empty slot. Finally, the technician verifies or initiates the RAID rebuild process using the controller interface to synchronize data and re-establish fault tolerance.
