,
TABLE 9-3
) indicate a hardware problem,
several types of software programs are available to supply information about the
problem.
9.3.1 Error Messages
Error messages and other system messages are saved in the

9.3.2 SunVTS
The latest version of SunVTS™ (online validation test suite) has several modes of
testing, including low-impact testing, which can run with minimum affect on
customer applications.
The SunVTS can also be used to stress-test Sun hardware, either in or out of the
Solaris operating environment. By running multiple and multithreaded diagnostic
hardware tests, the SunVTS software verifies the system configuration and
functionality of most hardware controllers and devices.
SunVTS tests many board and system functions, as well as interfaces for Fibre
Channel, SCSI, and SBus interfaces. SunVTS accepts user-written scripts for
automated testing.
Refer to the SunVTS User’s Guide for starting and operating instructions.
