omconfig system shutdown
Use the omconfig system shutdown command to determine how the system shuts down. During system
shutdown, the default is to shut down the operating system before powering off the system. Shutting
down the operating system first closes down the file system before powering the system down. If you do
not want to shut down the operating system first, you can use the parameter osfirst=false. Table 5-28
shows the valid parameters for the command.
Example Shutdown Commands
To set the shutdown action to reboot, type:
omconfig system shutdown action=reboot
To bypass operating system shutdown before the system is powered off, type:
omconfig system shutdown action=reboot osfirst=false
Table 5-28. Shutdown Parameters

performing BIOS checks and reloading the operating system.
action=poweroff Turns the electrical power to the system off.
action=powercycle Turns the electrical power to the system off, pauses, turns the power
on, and reboots the system. Power cycling is useful when you want to
reinitialize system components such as hard drives.
osfirst=true | false true: Closes the file system and exits the operating system before
shutting down the system.
false: Does not close the file system or shut down the operating system
before shutting down the system.
