Enumerated Devices

Enumerated devices are physical devices with a one-to-one correspondence between a particular device node and a host where that device node is present. Examples of this category include various disk and tape devices, such as /dev/dsk/c0t0d0s0 and /dev/rmt/0l. Nearly all physical devices belong to this category. This is the default category for all non-pseudo devices.
