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.
