OpenBoot Emergency Procedures
The following sections describe how to perform the functions of the Stop commands
on systems that use USB keyboards. These same functions are available through the
ALOM software.
Stop-A Functionality
Stop-A (Abort) key sequence works the same as it does on systems with standard
keyboards, except that it does not work during the first few seconds after the server
is reset. In addition, you can issue the ALOM system controller
break
command.
Stop-N Functionality
Stop-N functionality is not available. However, the Stop-N functionality can be
closely emulated by completing the following steps, provided the system console is
configured to be accessible using either the serial management port or the network
management port.

To Restore OpenBoot Configuration Defaults
1. Log in to the ALOM system controller.
2. Type the following commands:
Note –
If you do not issue the
poweroff
and
poweron
commands or the
reset
command within 10 minutes, the host server ignores the
bootmode
command.
You can issue the
bootmode
command without arguments to display the current
setting.
