Automatic System Recovery Overview - Sun Oracle SPARC T3-2 Service Manual

Automatic System Recovery Overview

The 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:
CPU strands
■
Memory DIMMs
■
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.
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.
ASR Commands
TABLE:
Command
show components
set asrkey component_state=
Enabled
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.
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.
