Solaris x86 - Console GUI and CLI

On Solaris x86 servers, Console can be launched from both GUI and the CLI.

start /SP/console

or

Web GUI -> Remote Control -> Launch Remote Console

Both the consoles can show the POSt and grub load process. 
But once the OS is loaded after the OS selection screen, one of the screen can go Black based on the eeprom setting.

eg)

MySolaris:/root# prtdiag -v | head -1
System Configuration: Sun Microsystems SUN FIRE X4250
MySolaris:/root#
MySolaris:/root# eeprom | grep console
console=text
MySolaris:/root#


If console = 'ttya' then the serial console (/SP/console) will be active
If console = 'text' then the VGA port (i.e., the redirected remote console) will be active.

If you change the eeprom console setting, an O/S reboot will be needed.
