Omconfig System Shutdown Or Omconfig Servermodule Shutdown

Use the omconfig system shutdown or omconfig servermodule 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, use the osfirst=false parameter.

NOTE: The parameter osfirst=false is not available on YX3X generation and later systems. By default, on YX3X generation and later systems, the operating system shuts down before turning off the server during a remote shutdown.

The following table displays the valid parameters for the command.
