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.  

OPTIONS

-h, --help

-d, --disk
disk name of LED location. Names are sda,sdb,sdc,... Multiple names can be provided in a comma-delimited list.
-p, --port

-s, --status
status of the LED to set. LED status is: locate, fault, rebuild, off
-f, --freq
Set the frequency at which the LED should blink (in Hz). Frequency should be an integer between 1 and 10.

 

EXAMPLES

Set the locate LED on SDA with an Intel Intelligent backplane:
sgpio -d sda -s locate

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:
sgpio -d sda,sdb,sdc,sdd,sde,sdf -s fault
