## Power Cycle the Server

If a simple reset does not clear a system problem, you can power the server off and on with this procedure.

1. Shut down the Oracle Solaris OS.

   At the Oracle Solaris OS prompt, type the `shutdown -g0 -i0 -y` command. Then type `h` when prompted to halt the Oracle Solaris OS and to return to the `ok` prompt.

       # shutdown -g0 -i0 -y
       # svc.startd: The system is coming down.  Please wait.
       svc.startd: 91 system services are now being stopped.
       Jun 12 19:46:57 wgs40-58 syslogd: going down on signal 15
       svc.startd: The system is down.
       syncing file systems... done
       Program terminated
       r)eboot, o)k prompt, h)alt?

2. Switch from the system console prompt to the service processor console prompt by issuing the console escape sequence (by default, `#.`).

       ok #.
       ->

3. Using the ILOM CLI, type the `stop /SYS` command to perform a graceful shutdown of the server.

       -> stop /SYS
       Are you sure you want to stop /SYS (y/n)? y
       Stopping /SYS

       ->

   Note - To perform an immediate and ungraceful shutdown, use the `stop `-force` `-script` /SYS` or `stop `-script` /SYS` commands. These commands stop everything immediately. Ensure that all data is saved before entering these commands.

4. Type the `start /SYS` command.

       -> start /SYS
       Are you sure you want to start /SYS (y/n)? y
       Starting /SYS

       ->

   Note - To force a power-on sequence, use the `start `-script` /SYS` command.

5. Reconnect to the system console with the `start /HOST/console` command.

       -> start /HOST/console
       Are you sure you want to start /HOST/console (y/n)? y
       Serial console started.  To stop, type #.

   The system console displays various messages, followed by the `ok` prompt.
