Use this procedure when you need to shut down a stand-alone system.
Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
Shut down the system.
# init 5 |
For more information, see the init(1M) man page.
Alternately, you can use the uadmin command to shut down the system.
# uadmin 2 0 |
If you have an x86 based system that is running at least the Solaris 10 6/06 release, you can press and release the power button to initiate a clean system shutdown and turn off the system.
This functionality is equivalent to using the init 5 command to shut down a system. For more information, see What's New in Shutting Down and Booting a System.
Use the following table to verify that the system is at the run level that you specified in the init command.
Specified Run Level |
SPARC Based System Prompt |
x86 Based System Prompt |
---|---|---|
S (single-user level) |
# |
# |
2 (multiuser level) |
# |
# |
0 (power-down level) |
ok or > |
Press any key to reboot |
3 (multiuser level with NFS resources shared) |
hostname console login: |
hostname console login: |
# uadmin 2 0 syncing file systems... done Program terminated |
In this example, the init command is used to bring an x86 based stand-alone system to the level where it is safe to turn off power.
# init 0 # INIT: New run level: 0 The system is coming down. Please wait. . . . The system is down. syncing file systems... [11] [10] [3] done Press any key to reboot |
If you are bringing the system to run level 0 to turn off power to all devices, see How to Turn Off Power to All Devices.
In this example, the init command is used to bring a SPARC based stand-alone system to run level S (single-user level).
# init s # INIT: New run level: S The system is coming down for administration. Please wait. Unmounting remote filesystems: /vol nfs done. Print services stopped. syslogd: going down on signal 15 Killing user processes: done. SINGLE USER MODE Root password for system maintenance (control-d to bypass): xxxxxx single-user privilege assigned to /dev/console. Entering System Maintenance Mode # |
Regardless of why you shut down the system, you will probably want to return to run level 3, where all file resources are available, and users can log in. For instructions on bringing a system back to a multiuser level, see Chapter 12, Booting an Oracle Solaris System (Tasks).
