Dell EMC Server Administrator Storage Management 9.1

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.

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.
