Chapter 3 System Controller Alphabetical Command Reference 29
Description
This command adds a component to the blacklist. Blacklisting provides a list of
components that will not be tested and will not be configured into the domain when
you change the domain’s keyswitch from an inactive state to an active state or reboot
the domain.
Blacklist a component or device if you believe it may be failing intermittently.
When you disable any component, the subcomponents are also disabled. For
example, if you disable a CPU, the Ecache and memory that are also controlled by
the CPU is automatically disabled.
Devices can be the following (see
TABLE 3-3 and TABLE 3-4):
■ Ports (CPU on a CPU/Memory board and I/O controller on an I/O assembly)
■ Physical and logical memory banks
■ I/O buses
■ I/O cards
Blacklisting is done on a per domain basis. When you run the disablecomponent
command in a domain shell, the component is blacklisted for the current domain.
When you run the disablecomponent command from the platform shell, the
component is disabled in all of the domains.
Using this command, the platform shell blacklists supersede the domain shell
blacklists. For example, if a component is disabled in the platform shell, it will be
disabled in all domains.
