Starting and Stopping the Computer System
3-10
014–002091
You may want to reset the computer system if it seems to be experiencing intermittent
errors; often the process of restoring hardware components to the powerup state
resolves temporary problems.
Resetting the hardware without cycling power is called a
warm reset
; turning power off
and then on again is a
cold reset
. With a cold reset, your system goes through powerup
testing and its automatic boot sequence, as described in the Powering Up" section at
the beginning of this chapter. With a warm reset, your computer system restores
system board components to their powerup state and displays the System Control
Monitor (SCM) command interpreter prompt, but does not proceed through powerup
tests or automatically boot your operating system.
You can perform a warm reset without pressing the reset switch by using the SCM
RESET command while at the SCM prompt, as follows:
SCM>
(or,
SCM>
)
Restarting Your System
Each time you turn power on, your system goes through powerup testing and its
automatic boot sequence, as described in the Powering Up" section at the beginning
of this chapter. It is not necessary to power down completely in order to restart your
operating system, however.
If you shut down your operating system to the SCM prompt or press the reset switch
(as described in the previous sections), you can restart your operating system by
entering the BOOT command at the SCM prompt, as follows:
SCM>
(or,
SCM>
)
When you use the BOOT command without an argument, the computer system uses
its default boot path and boots the same file it uses at every powerup. If you have not
set a default boot path, it looks for a bootable file on the first SCSI disk
.
Refer to
Chapter 5 for additional information about the default boot path and the automatic
boot sequence; Appendix B contains detailed information about the SCM BOOT
command and boot syntax.
