If this is a cluster or there are NFS mounts you will need special instructions to shut down in a sensible manner. These instructions may or may not include a "shutdown" command.

You will need to know more about you "special login thru a console" and what piece of hardware you are connected to and how to toggle between console and server remote management. Is it an iLO (Integrated Lights-Out) or a MP (Management Processor) or a Web Console? We assume it is not just a telnet session.

The unix "shutdown" command just shuts down the Operating System and halts the processor. It does not turn the power off. Most remote power controls only control the system unit not any add-on hardware such as disc arrays.

Beware that unix "shutdown" does not shut down databases etc. unless "rc" scripts have been installed to achieve this.

If you are in a hurryand you have already closed all applications and client connection, this method answers any prompts:

Code:

cd /;/sbin/shutdown -h -y now
