Question
A company's RAID array has degraded performance and a blinking red light on one of the bays. Which of the following should a technician replace?
Options
- AHDD
- BCPU
- CPSU
- DRAM
Explanation
A blinking red light on a RAID array bay, combined with degraded performance, almost universally indicates a failing or failed hard disk drive within the array.
Common mistakes.
- B. A CPU failure would typically lead to a complete system crash or boot failure, not just degraded RAID performance with a specific bay light.
- C. A PSU (Power Supply Unit) issue would affect the entire system's power, potentially leading to a complete shutdown or erratic behavior, not a single bay's light and degraded RAID.
- D. RAM issues often cause system crashes, blue screens of death, or application errors, but are not directly indicated by a blinking red light on a drive bay in a RAID array.
Concept tested. RAID array troubleshooting - failed drive identification
