1.2Firmware and Utilities Overview

Firmware residing in ROM on CPU and other modules in the system provides commands for booting the operating system, testing devices and I/O adapters, and other tasks useful in operating and maintaining a running system. You type commands at the console device.

SRM Console

Systems running the Tru64 UNIX or OpenVMS operating systems are configured from the SRM console, a command-line interface (CLI). From the CLI you can enter commands to configure the system, view the system configuration, and boot the system.

System Control Manager (SCM)

The SCM firmware allows the user to access the system remotely. In addition, the SCM:

Monitors and notifies the user of power or temperature alert conditions

Controls initial system power-up

Manages hard partitions

LFU (Loadable Firmware Update Utility)

You can boot this utility (with the SRM boot command) whenever you need to update the SRM console firmware or I/O device firmware. The CD with the AlphaServer firmware is updated periodically.
