ASR enables the server module to automatically configure failed components out of operation until they can be replaced. In the server module, ASR manages the following components:
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, add, or remove components (asrkeys) from the ASR blacklist. You run these commands from the Oracle ILOM prompt.
Note - The asrkey values vary from system to system, depending on how many cores and memory are present. Use the show components command to see the asrkey values on a given system.
After you enable or disable a component, you must reset (or power cycle) the server module for the component’s change of state to take effect. See the SPARC and Netra SPARC T4 Series Servers Administration Guide
