Using the System Exercise Tools
This appendix describes how you test system components when you see
error messages that relate to a component or if you observe unexpected
behavior.
F.1 System Exercisers
The Tru64 UNIX system provides a set of exercisers that you can use to
troubleshoot your system. The exercisers test specific areas of your system,
such as file systems or system memory. This chapter explains how to use
the exercisers by addressing the following topics:
• Running the system exercisers (Section F.1.1)
• Using exerciser diagnostics (Section F.1.2)
• Exercising file systems by using the
fsx command (Section F.1.3)
• Exercising system memory by using the memx command (Section F.1.4)
• Exercising shared memory by using the shmx command (Section F.1.5)
• Exercising disk drives by using the diskx command (Section F.1.6)
• Exercising tape drives by using the tapex command (Section F.1.7)
• Exercising communications systems by using the cmx command
(Section F.1.8)
In addition to the exercisers documented in this chapter, your system might
also support the DEC Verifier and Exerciser Tool (VET), which provides a
similar set of exercisers. With the release of Tru64 UNIX Version 4.0, VET
is no longer present on the installation kit as an optional subset. Instead,
VET software is on the Tru64 UNIX Firmware CD-ROM.
F.1.1 Running System Exercisers
To run a system exerciser, you must be logged in as superuser and
/usr/field must be your current directory.
The commands that invoke the system exercisers provide a flag for
specifying a file where diagnostic output is saved when the exerciser
completes its task.
