sgpio − captive backplane LED control utility
sgpio [−h] [−V] [[−d|−−disk <device>[,<device>...]] | [−p|−−port <port>[,<port>...]]] [−s|−−status <status>] [−f|−−freq <frequency>]
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.
−h, −−help
displays a short help text
−V, −−version
displays the utility and AHCI SGPIO specification
−d, −−disk
disk name of LED location. Names are sda,sdb,sdc,... Multiple names can be provided in a comma-delimited list.
−p, −−port
SATA port number of LED location, can be used if a disk name is no longer valid. 0,1,2,3,... Multiple ports can be provided in a comma-delimited list.
−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.
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
sgpio should return zero when successful. It will return with a non-zero value if there was a failure.
