The LEDs on the drive carrier indicate the state of each drive. Each drive carrier has two LEDs: an activity LED (green) and a status LED (bicolor, green/amber). The activity LED blinks whenever the drive is accessed.
If the drive is in the Advanced Host Controller Interface (AHCI) mode, the status LED indicator does not power on.
Drive status indicator behavior is managed by Storage Spaces Direct. Not all drive status indicators may be used.
Drive status indicator code | Condition |
---|---|
Blinks green twice per second | Indicates that the drive is being identified or preparing for removal. |
Off | Indicates that the drive is ready for removal. The drive status indicator remains off until all drives are initialized after the system is powered on. Drives are not ready for removal during this time. |
Blinks green, amber, and then powers off | Indicates that there is an unexpected drive failure. |
Blinks amber four times per second | Indicates that the drive has failed. |
Blinks green slowly | Indicates that the drive is rebuilding. |
Solid green | Indicates that the drive is online. |
Blinks green for three seconds, amber for three seconds, and then powers off after six seconds | Indicates that the rebuild has stopped. |
