Using Hardware Utilities
5-2 Fault Tolerant System Administration (R1004H) HP-UX version 11.00.03
■ log changes in the device’s status
■ display the device’s state on demand
During normal operation, the system periodically checks each hardware path. If a
device is not operating, is missing, or is the wrong model number for that
hardware path’s definition, the system logs messages in the system log file and, if
configured, sends a message to the console.
Using Hardware Utilities
Replacing or deleting some devices requires only that you insert or remove the
units from the system. Other tasks require that you enter certain commands. The
primary hardware utilities are addhardware and ftsmaint.
Use the addhardware command when you add new hardware to a running
machine. See the HP-UX Operating System: Peripherals Configuration (R1001H) and
the addhardware(1M) man page for information about adding and configuring
hardware.
You can use the ftsmaint command for many tasks, including the following:
■ listing and determining hardware paths
■ displaying hardware status information
■ enabling and disabling hardware devices
■ attempting to bring a faulty device back into service
■ displaying and managing MTBF statistics
■ updating PROM code
This chapter describes various uses of the ftsmaint command. See Appendix B,
“Updating PROM Code,” for procedures to update PROM code and the
ftsmaint(1M) man page for information about all options and services.
Determining Hardware Paths
You can identify each piece of hardware configured on a system by its hardware
path. For many system administration tasks, you must determine the physical
location of a device when given its hardware path, or supply a hardware path in a
command line. The hardware path is usually indicated by the hw_path argument
in the command syntax.
