4.2 Taking the System to Standby Mode
To take the system to Standby mode:
1. Notify users that the system is going down.
2. Back up the system files and data to tape, if necessary.
3. Take the system to Standby mode by typing the
shutdown
command at the
lom>
prompt.
Refer to the system administration manual. The following actions occur when the
system is taken to Standby mode:
■
The Solaris OS is cleanly shut down.
■
The system is powered off to Standby mode, which is the lowest level of
operation.
■
The system controller and one fan remain running.
4. Turn off each external drive and the expansion cabinet(s) (if any).
Caution – Do not use the On/Standby switch to power off the system. Pressing the
On/Standby switch longer than four seconds will abruptly terminate the Solaris OS.
This method
is not the recommended method to shut down the operating system. If
you abruptly terminate the operating system, you may damage the file system.
4.2.1 Alternate Method to Halt the Solaris OS
Besides using the system controller
shutdown
command to halt the Solaris OS, you
can also shut down the Solaris OS as a UNIX

superuser:
1. Halt the Solaris OS as a UNIX superuser.
Refer to the system administration manual.
2. Wait for the system-halted message and the
ok>
prompt.
