6.4 Suppressing Starting Oracle Solaris at Power-on
This section describes how to suppress starting Oracle Solaris when powering on the SPARC M12/M10.
Note - In the SPARC M12/M10, even if you set the operation panel mode switch to "Service," you cannot suppress starting Oracle Solaris.
The method of suppressing starting Oracle Solaris at power-on in the SPARC M12/M10 is described below.
- Suppressing starting Oracle Solaris in the control domain   

 Perform either of the following operations. After this operation, Oracle Solaris stops in OpenBoot PROM.
 - Set the value of the OpenBoot PROM environment variable auto-boot? to false with the setpparparam command of the XSCF firmware.
[Example] XSCF> setpparparam -p 0 -s bootscript "setenv auto-boot? false"

 - Set the value of the OpenBoot PROM environment variable auto-boot? to false with the eeprom command of Oracle Solaris.
For details of the setpparparam command, see the man page of the setpparparam(8) command or the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 XSCF Reference Manual.
For details on changing the OpenBoot PROM environment variables with the XSCF firmware, see "8.9.1 OpenBoot PROM Environment Variables That Can be Set With the XSCF Firmware."
- Suppressing starting Oracle Solaris in the guest domain

 Set guestboot=off by the setpparmode command of the XSCF firmware.
 [Example] XSCF> setpparmode -p 0 -m guestboot=off
For details of the setpparmode command, see the man page of the setpparmode(8) command or the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 XSCF Reference Manual.
