Device Names

This page contains information about the similarities and differences between different versions of Unix.

Examples of Device File Names

AIX 4.X HP-UX 11.X IRIX 6.X Linux Solaris 2.X
Disk * /dev/hdisk1 /dev/dsk/c0t4d0s0 /dev/dsk/dks0d2s0 /dev/hda0
/dev/sda0		 /dev/dsk/c0t0d0s0
Tape, rewinding ** /dev/rmt0 /dev/rmt/0mb /dev/tape /dev/ht0
/dev/st0		 /dev/rmt/0
Tape, non-rewinding ** /dev/rmt0.1 /dev/rmt/0mnb /dev/nrtape /dev/nht0
/dev/st0
/dev/tape		 /dev/rmt/0n
CD * /dev/cd0 /dev/dsk/c0t2d0 /dev/scsi/sc0d0l0 /dev/cdrom /dev/dsk/c0t6d0s0

* Devices with cntndnsn indicate the controller, SCSI target address, drive number, and slice (partition). For example: 

c0t3d0s6 = controller 0
           target 3
           drive 0
           slice (partition) 6
** A complete list of tape device files can usually be found in man pages:
