Using The Halt Button - Compaq AlphaServer 1200 User Manual

3.11

Using the Halt Button

Use the Halt button to halt the DIGITAL UNIX or OpenVMS operating system
when it hangs, clear the SRM console password, or force a halt assertion, as
described in Section 3.12.
Using Halt to Shut Down the Operating System
You can use the Halt button if the DIGITAL 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 4.11.
The Windows NT operating system does not support halts on this system. Pressing
the Halt button during a Windows NT session has no effect.
Using Halt to Clear the Console Password
The SRM console firmware allows you to set a password to prevent unauthorized
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 4.8
describes the procedure.
