Keywords:  syntax, dsk, activesync, treo, enc
A name referring to hardware. The device for the CD-ROM is usually /dev/dsk/c0t6d0s2 for Solaris 2.x, and /dev/sr0 for Solaris 1.x. It may be different depending on your machine or on how you configure it.
The physical disk device name (or disk access name).
The device name or address used to access a physical disk, such as c0t0d0. The c#t#d# syntax identifies the controller, target address, and disk. In a SAN environment, it is more convenient to use enclosure-based naming, which forms the device name by concatenating the name of the enclosure (such as enc0) with the disk's number within the enclosure, separated by an underscore (for example, enc0_2). The term disk access name can also be used to refer to a device name.
Literal reference to a device, used to gain access to the device through an xx_open( ) function, where xx is the prefix defining the device type to be opened.
