Many ways to access OK prompt

  1. By pressing Stop A key sequence on a Sun Keyboard.
  2. By typing #init 0 if your system boots up directly .
  3. Pressing ctrl-break or shift-break on a pc keyboard if using pc as console through serial port.
  4. If auto-boot feature is enabled system directly boots up and gives you a # prompt. You can disable auto-boot so next time it stays at ok prompt for starting installation.
    1. #/usr/platform/sun4u/sbin/eeprom auto-boot?=false
    2. reboot the system.

 

Access OK prompt from ILOM

To access the OK prompt from the ilom, use the following commands:

# set /HOST send_break_action=break
# start /SP/console

if you receive the following:

FATAL: system is not bootable, boot command is disabled

use the following commands:

# set /HOST/bootmode script="setenv auto-boot? false"
# start /SP/console

and then:

{0} boot -F failsafe
or
{0} boot ?s
or
{0} boot -r
or
{0} boot cdrom

Ubuntu 10.10 initial steps

Just a few of the common extra packages and config settings I do.

Install ssh-server and kernel headers

apt-get install linux-generic linux-headers-generic linux-image-generic ssh

VirtualBox (if hardware can handle it)
echo "deb http://download.virtualbox.org/virtualbox/debian maverick contrib non-free" >> /etc/apt/sources.list
wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add - 
apt-get update
apt-get install virtualbox-4.0

Install beep (nice to have some audible feedback at times… and annoy people too)

apt-get install beep
modprobe -a pcspkr

Also add
modprobe -a pcspkr to /etc/rc.local
