Setting Console Security

You can set the SRM console to secure mode to prevent unauthorized persons from
modifying the system parameters or otherwise tampering with the system from the
console.
When the SRM is set to secure mode, you can use only three console commands:
•
The boot command, to boot the operating system.
•
The continue command, to resume running the operating system if you have
inadvertently halted the system.
The boot command cannot take command-line parameters when the console is in secure
mode. The console boots the operating system using the environment variables stored in
NVRAM (boot_file, bootdef_dev, boot_osflags).
The console security commands are as follows:
set password
set secure
clear password
login
NOTE: The security features work only if access to the system hardware is denied to
unauthorized persons. Be sure the system is available only to authorized persons.
These commands put the console into secure mode.
Exits secure mode.
Turns off console security for the current session. Once you enter the
login command in secure mode, you can enter any SRM command as
usual. However, the system automatically returns to secure mode
when you enter the boot or continue command or when you reset the
system.
