Guidelines for Booting a System
Keep the following in mind when booting 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 Intel system.
-
A system can be rebooted by turning the power off and then back on. This is not a clean shutdown because system services and processes are terminated abruptly. However, turning a system's power off and back is an alternative for emergency situations.
-
SPARC based and IA based systems use different hardware components for booting. These differences are described in Chapter 12, The Boot Process (Reference).
