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.
