The term ASR stands for Automatic System Recovery. The version of ASR
   referred to by this document is that which is used in the V210, 240,
   and V250. The document will provide examples of user level
   commands that would likely be used by someone troubleshooting or
   administering a system.
   
   
    List of user level commands and their uses:
    .asr              - Displays all devices that are disabled and states
                         if the device was disabled by USER
                         (by way of asr-disable) or FWDIAGS (POST or
                         OBDIAG)
     asr-clear         - Clears the state of any disabled device.This
                         includes devices disabled by a POST or OBDIAG
                         failure
     asr-list-keys     - Lists the device names available for use with
                         asr-enable and asr-disable commands
     asr-disable xxx   - Disables a device from use.It will appears as
                         "Disabled by USER" in the output of the .asr
                         command.Where "xxx" is a device name as
                         indicated the the output of "asr-list-keys"
                     
     asr-enable xxx    - Enables a previously disabled device.Where "xxx"
                         is a device name as indicated the the output
                         of "asr-list-keys"
                        
    Examples:
   
     {1} ok .asr
     scsi                    Disabled by USER
                             No reason given
     {1} ok asr-clear
     {1} ok .asr
     There are no devices disabled by ASR.
     
     {1} ok asr-list-keys
     key = usb                   /pci@1e,600000/@a   
     key = ide                   /pci@1e,600000/@d   
     key = net2&3                /pci@1d,700000/@2   
     key = net0&1                /pci@1f,700000/@2   
     key = scsi                  /pci@1c,600000/@2   
     key = hcm                   /pci@1c,600000/@1   
     key = pci2                  /pci@1e,600000/@2   
     key = pci1                  /pci@1e,600000/@3   
     key = pci0                  /pci@1d,700000/@1   
     key = dimm7            
     key = dimm6            
     key = dimm5            
     key = dimm4            
     key = dimm3            
     key = dimm2            
     key = dimm1            
     key = dimm0      
     
     {1} ok asr-disable scsi
     {1} ok .asr
     scsi                    Disabled by USER
                             No reason given
     {1} ok asr-enable scsi
     {1} ok .asr
     There are no devices disabled by ASR.
   Additional Notes:

    ASR will issue a summary message in the timeframe after the
    banner but before booting the O/S when the system is reset:

    注意：/etc/path_to_inst为硬件与OS所识别的硬件之间的对应关系；如果有硬件的更新，可执行devfsadm来同步此文件；
    如果在安装操作系统之前，有某些硬件已被ASR所禁用，则必须手工修改/etc/path_to_inst之间对应关系。
