Figure 1–6 Halt/Reset Button - DS10L

1.9.1 Using Halt to Shut Down the Operating System
You can use the Halt button if the Tru64 UNIX or OpenVMS operating system
hangs. Pressing the Halt button halts the operating system back to the SRM
console firmware. From the console, you can use the crash command to force a
crash dump at the operating system level. See Section 2.12 for an example.
1.9.2 Using Halt to Clear the Console Password
The SRM console firmware allows you to set a password to prevent unauthor-
ized access to the console. If you forget the password, the Halt button, with the
login command, lets you clear the password and regain control of the console.
Section 2.9.2 describes the procedure.
