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
■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.
