3-46 SPARC Enterprise T1000 Server Service Manual • April 2007
The database that contains the list of disabled components is called 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
must remove the component from the ASR blacklist.
The ASR commands (
TABLE 3-7) enable you to view, and manually add or remove
components from the ASR blacklist. These commands are run from the ALOM CMT
sc> prompt.
Note – The components (asrkeys) vary from system to system, depending on how
many cores and memory are present. Use the showcomponent 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 with power on there is no effect to the
system until the next reset or power cycle.
3.7.1 Displaying System Components
The showcomponent command displays the system components (asrkeys) and
reports their status.
● At the sc> prompt, enter the showcomponent command.
