2.6 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 two 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_flags).
The console security commands are as follows:
set password
set secure
These commands put the console into secure mode.
clear pass-
word
Exits secure mode.
login 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 automati-
cally returns to secure mode when you enter the boot or
continue command or when you reset the system.
NOTE: The security features work only if access to the system hardware is de-
nied to unauthorized persons. Be sure the system is available only to
authorized persons.
