Drive carrier LEDs

Drive carrier LEDs

This document providesĀ explanations for drive carrier LED behavior.Ā Drive carriers will typically have two LEDs for activity and drive faults.

Activity LED

  • Color:
    • Green or blue, depending on the backplane
  • Flashing:
    • Drive activity is present
  • Off:
    • Drive not present, or if using SATA drives, no activity on the disk
  • On:
    • SAS drive is present, no activity

Fault LED

  • Color:
    • Red
  • Flashing:
    • Drive is a hot spare, or unassigned
  • On:
    • Drive has failed, or is incomplete (in the middle of a rebuild)
    • For drives in the middle of a rebuild, the fault light and activity light will be simultaneously active until the rebuild completes
