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.
