Sun Microsystems 440 manual Stop-A Functionality, Stop-N Functionality

OpenBoot Emergency Procedures for Systems With USB Keyboards

The following sections describe how to perform the functions of the Stop commands on systems that use USB keyboards, such as the Netra 440 server. These same functions are available through Sun Advanced Lights Out Manager (ALOM) system controller 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. For more information, see “Reaching the ok Prompt” on page 10.

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 command:

sc> bootmode reset_nvram
