Guidelines for Booting a System

Keep the following in mind when you boot a system:

• After a system is shut down, it is booted by using the boot command at the PROM level on a SPARC based system or by using the boot command at the Primary Boot Subsystem Menu on an IA based system.

• A system can be rebooted by turning the power off and then back on. This method is not a clean shutdown because system services and processes are terminated abruptly. However, turning a system's power off and back on is an alternative for emergency situations.

• SPARC based systems and IA based systems use different hardware components for booting. These differences are described in Chapter 15, The Boot Process (Reference).
