Logical device names are used by system administrators or users to access the
disk (partitions) and tape devices for such tasks as mounting and backing up
file systems.
Sun systems use the following naming conventions to describe the logical
device name for a disk device connected to a bus-oriented controller such as the
small computer system interface (SCSI) and the Intelligent Peripheral Interface
(IPI).
/dev/[r]dsk/cwtxdys<
i>z
Where:
w is the controller number
x is the target number
y is the disk number
z is the slice or partition number
Example:
# ls -l /dev/dsk/c0t3d0s0
Logical device names are stored in the /dev/directory in
subdirectories containing both character and block devices. All logical device
names are symbolic links to the physical device names in the /devices
directory.
