Blinking And Unblinking A Physical Disk
Does my controller support this feature? See Supported Features.
The Blink task allows you to find a disk within an enclosure by blinking one of the light-emitting diodes (LEDs) on the disk. You can use this task to locate a failed disk.
On most controllers, the Blink task automatically cancels after a short duration such as 30–60 seconds. Select Unblink to cancel the Blink task or to stop the LED on the physical device that is blinking indefinitely.
