ROM Functions and Utilities
Each MSA500 controller has a ROM that contains the controller firmware.
Recovery ROM
The Recovery ROM feature stores two complete firmware images in the ROM: one
active image and one backup image. When the controller is powering up, it checks
both firmware images to be sure they are valid. If either image is invalid, the system
overwrites the invalid image with the valid image. This process, commonly called
auto-flashing, is performed automatically by the controller and does not require any
user intervention. The controller display provides messages for the status of this
process.
Firmware Upgrades
The ROM flash tool enables system administrators to efficiently upgrade array
controller ROM images. This tool has the following features:
• Supports Microsoft® Windows NT® 4.0, Windows® 2000, Novell NetWare
(offline only), and Linux operating systems
• Integrates with other software maintenance, deployment, and operating system
tools
• Automatically checks for hardware, firmware, and operating system
dependencies, and installs only the correct ROM upgrades required by each
target controller
For firmware procedures, refer to the SmartStart CD.
