# How to get IMPI SOL (Serial console Over LAN) work
# MB: SuperMicro X8DAH+-F => Winbond WPCM450 BMC

# no need to mangle GRUB menu (/rpool/boot/grub/menu.lst) anymore.
# usually one will find something like append boot params to the kernel line
# -B console=ttyb,ttyb-mode="9600,8,n,1,-",input-device=ttyb,output-device=ttyb 
# or something like
# serial [--unit={0|1|2|3}|--port={0x3f8|0x2f8|0x3e8|0x2e8}] 
#	--speed=9600 --word=8 --parity=no --stop=1 

# just add appropriate params to your /boot/solaris/bootenv.rc using eeprom
# ignore 'Default /boot/grub/menu.lst entry is not controlled by bootadm.' msg
eeprom console=ttyc
eeprom ttyc-mode='115200,8,n,1,-'
eeprom ttyc-rts-dtr-off='false'
eeprom ttyc-ignore-cd='true'

# depending on the speed we will use, we need to make sure, that an 
# appropriate entry exists in /etc/ttydefs (see ttydefs(4), sttydefs(1M), termio(7I) ).
# Since there is none for 115200 we add one labeled as 'console6':
sttydefs -a console6 -i '115200 hupcl opost onlcr ofill' -f '115200'

# Usually that would be sufficient, however since 
# http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/i86pc/boot/boot_console.c
# http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/i86pc/io/consplat.c
# http://src.illumos.org/source/xref/illumos-gate/usr/src/cmd/boot/bootadm/bootadm_hyper.c
# accepts only ttya or ttyb as valid tty, ttyc doesn't get hooked up to
# /dev/console. However, we can workaround this shortcoming by assign a virtual
# terminal (VT) to ttyc (thanx a lot to irc://#illumos/bdha for digging this
# detail out :)). This way we have not access to the system console, but at
# least access to the system via a serial line.
# In this example we assign the vt6 to /dev/ttyc.
svccfg -s svc:/system/console-login:vt6 setprop ttymon/device = /dev/ttyc
svccfg -s svc:/system/console-login:vt6 setprop ttymon/label = console6
svccfg -s svc:/system/console-login:vt6 setprop ttymon/terminal_type = vt100
# if vtdaemon is not yet installed on your system (gets removed when upgrading
# from  S11X -> S11), install virtual-console:
pkg install virtual-console
# if vtdaemon is not yet enabled:
svcadm enable vtdaemon:default
svcadm refresh console-login:vt6
svcadm enable console-login:vt6
# otherwise
svcadm refresh console-login:vt6
svcadm restart console-login:vt6

# Optional: Per default root is allowed to login on the system console, only.
# To be able to login as user root on the vt6, one needs to comment out the
# following line in /etc/default/login
CONSOLE=/dev/console

# Make sure, the settings in the BIOS are correct as well
# To circumvent fastreboot and get directly into the BIOS we use 'reboot -p'
# However, in this case we need to update the boot archive manually ('init 6'
# does it autopmatically but uses per default fastreboot):
bootadm update-archive
reboot -p

# BIOS:
# - as usual press DEL to get into the BIOS
# - go to Advanced | Remote Access Configuration
# adjust your settings: e.g.:
          Advanced
