10.3.2.2 Performing a Forced Shutdown
Only use a forced shutdown when you cannot perform a graceful shutdown. If at
any point in these procedures your system becomes able to take direction, return to
the graceful shutdown procedure.
Caution – If you use the forced shutdown method, all unsaved data changes are
lost.
To force the workstation to power down:
1. Identify hung processes, if needed.
a. If needed, use the rlogin or telnet commands to access the hung system
from another system.
b. From the command line in a terminal window, execute a ps command to
identify the process id number for the hung process.
Refer to the respective command man pages for syntax information.
2. Terminate a hung process, if needed.
The shutdown commands described here are used to close a system shell or stop an
application or process. They do not take the workstation to a powered down state.
Execute these commands from the command line in a terminal window. Refer to the
command man page for syntax information.
System Exit - Use the exit command to stop all processes in a specified shell and
■
close out the shell. Use this method when an application or process is frozen in
the shell and you have decided to force the shell to stop action and release the
system. This typically exits any child processing initiated through this shell, but
background processes might continue to run. It might be necessary to execute this
command from another workstation or another terminal window. If you are in a
GUI, click the close box on the terminal window.
Process Kill - Use the kill command to shut down a single process. Use this
■
command when an application or process is frozen and you have decided to force
an it to quit and release the system. It might be necessary to execute this
command from another workstation or another terminal window.
If either of these commands releases your system return to the graceful shutdown
procedure. Refer to "Shutting Down Gracefully" on page
