Power Off the Server
Performing a graceful shutdown makes sure all of your data is saved and the system is ready for
restart.
1. Log in as superuser or equivalent.
Depending on the nature of the problem, you might want to view the system status, the log files,
or run diagnostics before you shut down the system. Refer to the server administration guide for
log file information.
2. Notify affected users.
Refer to your Solaris system administration documentation for additional information.
3. Save any open files and quit all running programs.
Refer to your application documentation for specific information on these processes.
4.
Shut down the Solaris OS.
Refer to the Solaris system administration documentation for additional information.
