3.7 Managing Components With Automatic
System Recovery Commands
The Automatic System Recovery (ASR) feature enables the server to automatically
configure failed components out of operation until they can be replaced. In the
server, the following components are managed by the ASR feature:
■
UltraSPARC T1 processor strands
■
Memory DIMMS
■
I/O bus
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 3-11
) enable you to view, and manually add or remove
components from the ASR blacklist. You run these commands from the ALOM CMT
sc>
prompt.
