Recovery ROM
Each MSA1000 Controller contains ROM (Read-Only Memory), which holds the
firmware that operates the controller. 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 ensure
they are valid. If either one is not, the valid image will be copied on top of the
invalid image to correct it. This is referred to as auto-flashing. All of this
functionality is done automatically by the controller and does not require any user
intervention.
