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
manually add or remove components (asrkeys) from the ASR blacklist. You run
these commands from the ILOM -> prompt.

set asrkey component_state=
Disabled
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.
