Before anyone can use your computer system, it must be
started. This chapter briefly discusses how to start and restart the system. It also discusses recovering from system failure.
"System startup" refers to the procedure for starting the computer software, the operating system, and other programs that you use. It rarely refers to turning on the power to the computer, disk drives, tape drives, printers, and the console. It does not refer to installing and configuring your system for any new release. (A separate installation guide comes with every new release.) During normal use, computer hardware remains powered on. If the power to the hardware is ever turned off, contact your system manager.
In this chapter, you will find the procedures to perform the following tasks:
Starting the system under normal conditions
Starting the system after a scheduled shutdown
Recovering from a system failure
