HP-UX version 11.00.03 Administering Fault Tolerant Hardware 5-3
A hardware path specifies the addresses of the hardware devices leading to a
device. It consists of a numerical string of hardware addresses, notated
sequentially from the bus address to the device address.
You can use the ftsmaint ls command to display the hardware paths of all
hardware devices in your system. You can also use the standard ioscan
command to display hardware paths. See the HP-UX Operating System: Peripherals
Configuration (R1001H) and the ioscan(1M) man page for more information about
this command.
Physical Hardware Configuration
This section explains how hardware paths are used to describe the physical
hardware devices on Continuum systems.
– For a description of the components of a Continuum Series 400 or 400-CO
system, see the HP-UX Operating System: Continuum Series 400 and 400-CO
Operation and Maintenance Guide (R025H).
Figure 5-1 shows the top three address levels of a Continuum hardware path.
