The amber and blue LEDs are controlled by the backplane (for internal physical
drives) or enclosure (for external physical drives). Controllers send
commands to the backplane or enclosure processor to set a logical state for
the LED, and the subsystem translates that LED state into the following flash
states:
Controller device state | Slot state | LED flash state |
failed | Device is faulty | On |
Rebuilding | Device is rebuilding | Slow flash |
Blink | Identify the device | Fast flash |
Other | No error | Off |
The green LED is an activity indicator for the physical drive and is controlled by the physical drive.
