Node Specific Devices

Node Specific Devices include devices that report particular information about the host where the device node is opened. An example of such a device is the /dev/kmem device. Opening this device gives access to host-specific information on the local host. Administrative pseudo device nodes used in configuring or gathering information about a particular device driver also fit this category. The Sun Cluster software ensures the creation of two user device nodes for each instance of a kernel device node in the cluster, so that the intended device node can be accessed both locally and remotely.
