NAME    [Toc]    [Back]

     sn0msc - Perform Origin and Onyx2 system controller operations

SYNOPSIS    [Toc]    [Back]

     sn0msc -r [ -x ] elsc_nvram_dev addr [ count ]
     sn0msc -w elsc_nvram_dev addr value [ count ]
     sn0msc -c elsc_controller_dev command

DESCRIPTION    [Toc]    [Back]

     sn0msc performs operations	on the Origin and Onyx2	Module System
     Controllers (MSCs).

     WARNING: If used improperly, this command may cause system	malfunction
     that is not fixed by system reset or power	cycling.  See below for	more
     information.

     There are three basic operations controlled by the	flags given:

     -r	  Reads	the MSC	NVRAM contents of a specific MSC device
	  (elsc_nvram_dev) at a	specific address (addr)	for a specific number
	  of bytes (count, default 1).	Output is in hex if the	-x flag	is
	  given, decimal otherwise.

     -w	  Writes the MSC NVRAM contents	of a specific MSC device
	  (elsc_nvram_dev) at a	specific address (addr)	with a specific	value
	  (value) for a	specific number	of bytes (count, default 1).

     -c	  Executes an MSC command on a specific	MSC device
	  (elsc_controller_dev)	and displays the output	from the MSC.  Certain
	  commands may cause the system	to function incorrectly.  Commands
	  that include white space must	be quoted from the shell.

     The NVRAM contains	2048 bytes.

     A corrupted MSC NVRAM can be repaired by writing zeroes over the entire
     contents of the NVRAM, power-cycling the MSC from the main	breaker	or
     power plug, and setting the module	number back to the correct value.
