1.8 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, theASR feature manages the following components:

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 (ASR Commands ) enable you to view, and manually add or remove components from the ASR blacklist. You run these commands from the ALOM CMT CLI sc> prompt.

Table 1-9 ASR Commands 

Command
Description
showcomponent
Displays system components and their current state.
enablecomponent asrkey
Removes a component from the asr-db blacklist, where asrkey is the component to enable.
disablecomponent asrkey
Adds a component to the asr-db blacklist, where asrkey is the component to disable.
clearasrdb
Removes all entries from the asr-db blacklist.

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, there is no effect to the system until the next reset or power cycle.


Displaying System Components

The showcomponent command displays the system components (asrkeys) and reports their status.

Example 1-12 Output of the showcomponent

sc> showcomponent
Keys:
 /SYS/MB/PCI_MEZZ
 /SYS/MB/PCI_MEZZ/PCIE4
 /SYS/MB/PCI_MEZZ/XAUI4
 /SYS/MB/PCI_MEZZ/PCIE5
 /SYS/MB/PCI_MEZZ/XAUI5
 /SYS/MB/PCI_MEZZ/PCIE6
 /SYS/MB/PCI_MEZZ/PCIE7
 /SYS/MB/PCI_MEZZ/PCIE8
 /SYS/MB/PCI_MEZZ/PCIE9
 /SYS/MB/PCI_AUX
 /SYS/MB/PCI_AUX/PCIX0
...
 /SYS/TTYA
State: Clean

Example 1-13 Output of the showcomponent

sc> showcomponent
Keys:
 /SYS/MB/PCI_MEZZ
 /SYS/MB/PCI_MEZZ/PCIE4
 /SYS/MB/PCI_MEZZ/XAUI4
 /SYS/MB/PCI_MEZZ/PCIE5

    ...
    /SYS/TTYA
Disabled Devices
  /SYS/MB/CMP0/L2_BANK0    Disabled by user

Disabling Components

The disablecomponent command disables a component by adding it to the ASR blacklist.

  1. At the sc> prompt, enter the disablecomponent command.
    sc> disablecomponent /SYS/MB/CMP0/BR1/CH0/D0
    Chassis | major: /SYS/MB/CMP0/BR1/CH0/D0 has been disabled. Disabled by user
  2. After receiving confirmation that the disablecomponent command is complete, reset the server so that the ASR command takes effect.
    sc> reset

Enabling Disabled Components

The enablecomponent command enables a disabled component by removing it from the ASR blacklist.

  1. At the sc> prompt, enter the enablecomponent command.
    sc> enablecomponent /SYS/MB/CMP0/BR1/CH0/D0
    Chassis | major: /SYS/MB/CMP0/BR1/CH0/D0 has been enabled.
  2. After receiving confirmation that the enablecomponent command is complete, reset the server for so that the ASR command takes effect.
    sc> reset
