device name

The physical disk device name (or disk access name).

The name of a device file, which represents a device. AIX syntax is Disk_#; HP-UX syntax is c#t#d#; Linux syntax is sda, where "a" could be any alphabetical letter; Solaris syntax is c#t#d#s#.

The device name or address used to access a physical disk, such as <code>hdisk3</code>, which indicates the whole of disk 3.

The device name or address used to access a physical disk, such as <code>c0t0d0</code>. The <code>c#t#d#</code> syntax identifies the controller, target address, and disk.

The device name or address used to access a physical disk, such as <code>sda</code> or <code>sda3</code>, where <code>sda</code> indicates the whole device, and <code>sda3</code> refers to the third partition on <code>sda</code>.

The device name or address used to access a physical disk, such as <code>c0t0d0s2</code>. The <code>c#t#d#s#</code> syntax identifies the controller, target address, disk, and slice (or partition).

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 <code>enc0</code>) with the disk’s number within the enclosure, separated by an underscore (for example, <code>enc0_2</code>). The term disk access name can also be used to refer to a device name.
