SRM Console 4-27

Example 4–16 Set Secure Command

P00>>> set secure # In this example a password

# has been set.

Console is secure. Please login.

P00>>> b dkb0

Console is secure - parameters are not allowed.

P00>>> login

Please enter the password: # Password is not echoed.

P00>>> b dkb0

(boot dkb0.0.0.3.1)

P00>>> set secure # Password has not been set.

Secure not set. Please set the password.

P00>>>

The set secure command enables secure mode without requiring a restart of the

console. If the password has been set, the console will be secured and only a small

subset of commands can be performed. If a password has not been set, you are

prompted to do so.

The syntax is:

set secure

Secure Mode Functions

When the console is in secure mode, the only commands recognized are boot, login,

continue, and start.

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.
