50 SPARC Enterprise T5120 and T5220 Servers Service Manual • July 2009
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.
The following ASR commands enable you to view and 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.
After you enable or disable a component, you must reset (or power cycle) the system
for the component’s change of state to take effect.
