setboot(1M) in HP-UX 11i v3

Lunpath

The physical hardware path leading to a SCSI logical unit. A SCSI LUN can have more than one lunpath.

Lunpath Hardware Path

Representation of a hardware path for a mass storage device. It is identical in format to a legacy

hardware path, up to the HBA. Beneath the HBA, additional addressing is represented in hexadecimal.

The string “0/2/1/0.0x50001fe1500170ac.0x4017000000000000” is an example of a lunpath

hardware path.

Multi-pathing

The detection, correlation, and coordinated usage of the multiple hardware paths leading to the same

LUN.

Persistent Device Special File

A DSF conforming to the naming model introduced in HP-UX 11i v3 to support lunpath hardware paths

and agile addressing. The file’s name contains an instance number, such as /dev/disk/disk#, and the

minor number has no hardware path information.
