HP-UX : Hardware Path

Before this, we discuss about how to check model or processor and today we will talk about the hardware path. In HP-UX , after boot process, the kernel assign every hardware to unique HP-UX hardware path, based on where the component is physically installed. The picture below, described each part of 1 hardware path all about.

ok, lets go with hands-on. We can check the hardware path using ioscan command, lets say we want to check disk, we execute this

# ioscan -fC disk                       // the options C is a "class" and f is a "full"

Class     I H/W Path       Driver S/W State   H/W Type     Description
