9.4.2 SunVTS
The latest version of SunVTS™ (on-line 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.
