Sun x2200 m2 and serial console output with Solaris 11.1

Sun x2200 m2 and serial console output

I am attempting to configure the serial console on a x2200 m2 system 
running Solaris 11.1.

I am close to having this working.  Specifically, I can move around in 
the ELOM.  I stop receiving output when I start the console from the /SP 
prompt.

i.e.

/SP    start /SP/AgentInfo/console

all output stops once I start the console.

Things are not locked however.  I can return to the SP prompt by issuing 
the provided ESC character.

In my attempt to research the problem, I came across this link:

http://docs.oracle.com/cd/E19121-01/sf.x2200m2/819-6601-22/index.html

and more specifically in this section.
==========================================

No Output When Running the start /SP/AgentInfo/console command

Solaris 10 6/06

1. Edit the /boot/solaris/bootenv.rc file to read:

setprop console ttyb

setprop ttyb-mode baudrate,8,n,1,-

where baudrate is the baud rate set in the SP and BIOS (9600 is the 
default value).

2. Edit the /boot/grub/menu.lst file to read:

kernel /platform/i86pc/multiboot -B console=ttyb

3. Edit the /kernel/drv/asy.conf file and add the following:

name=asy parent=isa reg=1, 0x2f8 interrupts=3;

4. Edit the /var/svc/manifest/system/console-login.xml file to read:

<propval name=label type=astring value=baudrate/>

where baudrate is the baud rate set in the SP and BIOS (9600 is the 
default value).

5. Save and exit the file.

6. Reboot the system using the following command:

# reboot -- -r
==========================================

this probably would have worked under Solaris 10.  Some of the files 
have moved.  Their contents have changed.  Solaris 11.x now has Grub 2, 
not Grub 1.x.  The file menu.lst no longer exist.

Thank you for any positive comments, I will summarize.
