To shut down and power off a server or group, use the stop command with the server or group keyword. Stopping a server or server group will initiate graceful shutdown of the operating systems and subsequent power off of the physical servers. If servers do not have an OS installed or do not shutdown, you can use the force subcommand to power off the server group.
The following graphic shows how to stop a group by using the Actions menu on the Servers By Group page, or by issuing the stop group command.
For syntax and parameter details, type help stop server or help stop group at the N1–ok command line.
