Resetting the Host Server

There are four ways to reset the host server from the sc> prompt:

• To perform a graceful reset of the server, type the poweroff command, followed by the poweron command. A graceful reset allows the Solaris operating environment to shut down. If you type the poweroff command without typing the poweron command, ALOM powers the host server down to standby mode.
• To force the server to shut down regardless of the state of the host server, type the poweroff -f command, followed by the poweron command. This resets the host server immediately, even if the Solaris operating environment fails or hangs for any reason. Note that this is not a graceful shutdown, and work might be lost.
• To reset the server immediately without a graceful shutdown, type the reset command. The reset -x option generates the equivalent of an XIR (externally initiated reset).
• To immediately bring the server to the OpenBoot PROM prompt (ok), type the break command.

Note: After you issue the command poweroff or poweroff -f, ALOM returns the following message:

SC Alert: Host system has shut down.

Wait until you see the message before issuing the poweron command.
