Unconfiguring and Reconfiguring
Devices
To support a degraded boot capability, the ALOM CMT firmware provides the
disablecomponent
command, which enables you to unconfigure system devices
manually. This command “marks” the specified device as disabled by creating an
entry in the ASR database. 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.
