NAME    [Toc]    [Back]

     hinv - hardware inventory command

SYNOPSIS    [Toc]    [Back]

     hinv [-v] [-s] [-m] [-c class] [-t	type] [-d dev] [-u unit]

DESCRIPTION    [Toc]    [Back]

     hinv displays the contents	of the system hardware inventory table.	 This
     table is created each time	the system is booted and contains entries
     describing	various	pieces of hardware in the system.  The items in	the
     table include main	memory size, cache sizes, floating point unit, and
     disk drives.  Without arguments, the hinv command displays	a one line
     description of each entry in the table.

     In	addition, on some systems hinv can display manufacturing information
     such as board name, part number and barcode number.

     The hinv options are:

     -v		Gives a	more verbose description of some items in the table.

     -c	class	Displays items from class.  classes are	processor, disk,
		memory,	serial,	parallel, tape,	graphics, network, scsi,
		audio, iobd, video, bus, misc, compression, vscsi, and
		display.

     -t	type	Displays items from type.  types are cpu, fpu, dcache, icache,
		memory,	qic, a2, and dsp.

     -s		When used with either the -c or	-t options, -s suppresses
		output.

     -d	dev	Restricts the output to	a kind of device among those currently
		present	in the system.	The devices that currently support
		this option are	cdsio, aso, ec,	et, ee,	enp, fxp, ep, gsn, hy,
		ipg, xpi, fv, gtr, mtr,	hippi, myri, and atm.

     -u	unit	Requests information for a single device unit number for a
		kind of	device specified with -d.

     -m		Displays physical manufacturing	information: board name, part
		number and barcode number.  When the -v	flag is	used in
		combination with -m the	physical location of each board	as a
		path under /hw is also displayed, see hwgraph(4D) for an
		explanation of the path.

     The hinv command, when used with the -c or	-t options, exits with a value
     of	1 if no	item of	the specified class or type is present in the hardware
     inventory table.  Otherwise, hinv exits with a value of 0.

     the corresponding driver is not configured	into IRIX.
