sgpio - Unix, Linux Command
NAME
sgpio - captive backplane LED control utility
SYNOPSIS
sgpio [-h] [-V] [[-d|--disk <device>[,<device>...]] | [-p|--port <port>[,<port>...]]] [-s|--status <status>] [-f|--freq <frequency>]
DESCRIPTION
Serial General Purpose Input Output (SGPIO) is a communication method used
between a main board and a variety of internal and external hard disk drive
bay enclosures. This utility can be used to control LEDs in an enclosure.
For more information about SGPIO, please consult the SFF-8485 Specification.

Set the locate LED on SDA to flash at 3 Hz for non-intelligent backplanes:
|
| |
sgpio -d sda -s locate -f 3
|
|
Set SATA port 2 with fault at a 3 Hz flash rate:
|
| |
sgpio -p 2 -s fault -f 3
|
|
Set disks sda through sdf to fault:
|
