Managing Faults 51

■ I/O subsystem

The database that contains the list of disabled components is referred to as the ASR

blacklist (asr-db).

In most cases, POST automatically disables a faulty component. After the cause of

the fault is repaired (FRU replacement, loose connector reseated, and so on), you

might need to remove the component from the ASR blacklist.

Note – For instructions on enabling or disabling ASR, see the SPARC Enterprise

T5440 Server Administration Guide.

The ASR commands (TABLE: ASR Commands on page 51) enable you to view and

manually add or remove components (asrkeys) from the ASR blacklist. You run

these commands from the ILOM -> prompt.

Note – The asrkeys vary from system to system, depending on how many cores and

memory are present. Use the show components command to see the asrkeys on a

given system.

Note – A reset or power cycle is required after disabling or enabling a component. If

the status of a component is changed, there is no effect to the system until the next

reset or power cycle.
