Chapter 6 Configuring System Firmware 115
In both cases, the devices in question are rendered unusable. So why make the
distinction? Occasionally, a device may fail in such a way that probing it disrupts the
system. In cases such as these, deconfiguring the slot in which the device resides is
more likely to contain the problem.
Deconfiguring All System Processors
You can use the asr-disable command to deconfigure all system processors.
Doing this will not crash the system. The OpenBoot system firmware, even though it
reports all processors as deconfigured, in actuality keeps one processor functioning
well enough to run the firmware.
Device Paths
When manually deconfiguring and reconfiguring devices, you might need to
determine the full physical paths to those devices. You can do this by typing:
The show-devs command lists the system devices and displays the full path name
of each device. An example of a path name for a Fast Ethernet PCI card is shown
below:
You can display a list of current device aliases by typing:
You can also create your own device alias for a physical device by typing:
ok show-devs
/pci@8,700000/pci@2/SUNW,hme@0,1
ok devalias
ok devalias alias_name physical_device_path
