Setting up a A3x00 in an independent controller configuration.
	1) Install the Raid Manager software, along with the patches
	   on both systems.
	2) Connect the A3x00 to one system to configure the luns to
	   go over the controllers you want them to.
	3) Edit the /etc/osa/rmparams files on each system to disable
	   RDAC failover.
		Change this line from FALSE to Rdac_SupportDisabled=TRUE
		This line is towards the bottom of the file.
	4) Run the following 'storutil' on the first system to let it
	   know you are  going to run independent controller configuration.
		storutil -c <raid module specifier> -i on
	5) Shutdown the systems and hook up one cable from each system
	   to a controller port.
	6) Run the same 'storutil' command on the second system so
	   that will also run independent controller configuration.
	7) Now the luns you configured on each controller will only be
	   seen from each the system connect to that controller.
NOTE: By configuring the A3x00 this way, you will no longer have the
redundancy of the controllers ability to failover luns.  Please be
aware of this major limitation prior to setting this up.
