Unconfiguring and Reconfiguring
Devices
To support a degraded boot capability, the ALOM firmware provides the
disablecomponent command, which enables you to unconfigure system devices
manually. This command creates an entry in the ASR database, with the specified
device flagged as disabled. Any device marked disabled, whether manually or by
the system’s firmware diagnostics, is removed from the system’s machine
description prior to the hand-off to other layers of system firmware, such as
OpenBoot PROM.
