2.9 Secure Mode When the console is in secure mode, the only commands recognized are boot, login, continue, and start. Placing the console in secure mode ensures that unauthorized persons cannot gain access to the system. The commands for console security are set password, clear password, and set secure. The login command turns off security features during the current console session. The boot command does not accept command line parameters in secure mode. The console boots using the environment variables stored in NVRAM (boot_file, bootdef_dev, boot_flags). After a successful boot, the console is secured if there is a valid password. The start and continue commands are valid on a secure console. After either command is executed, the console is secured if there is a valid password. This prevents an intruder from accessing the system. 2.9.1 Login Command and Secure Mode The login command turns off the security features, enabling access to all SRM console commands during the current session. The system automatically returns to secure mode as soon as the boot, continue, or start command is entered or when the system is initialized. When the login command is entered, the user is prompted for the current system password. If a password has not been set, a message is displayed indicating that there is no password in NVRAM. If a password has been set, this prompt is displayed: Please enter the password: If the password entered matches the password in NVRAM when the prompt is redisplayed, the console is no longer in secure mode and all console commands can be performed. NOTE: If you enter the login command when a halt assertion exists, the command fails, even if you enter the correct password. See Section 1.10 for information on halt assertion. 2-26 DS10 / DS10L Console Reference
