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 cancels once you select Unblink. Select Unblink to cancel the Blink task or to stop the LED on the physical device that is blinking indefinitely.
NOTE: The Blink and Unblink tasks are only
supported for hotswap physical disks (disks that reside in a carrier).
When using an Broadcom PCIe U320 controller, the Blink
and Unblink tasks apply to physical disks contained in
carriers that can be inserted into a server or an enclosure. If the
physical disk is not contained in a carrier but is instead designed
to be connected with a SCSI cable (typically a ribbon cable), then
the Blink and Unblink tasks are disabled.
