5.1 SunVTS
SunVTS is a software suite that performs system, subsystem, and configuration
testing. You can view and control a SunVTS session over a network. Using a remote
system, you can view the progress of a testing session, change testing options, and
control all testing features of another machine on the network.
You can run SunVTS software in three different test modes:
■ Connection mode verifies the presence of device controllers on all subsystems. This
typically takes no more than a few minutes and is a good way to “sanity check”
system connections.
■ Functional mode exercises only the specific subsystems you choose. This is the
default mode.
■ Auto Config mode automatically detects all subsystems and exercises them in one
of two ways:
■ Confidence testing – performs one pass of tests on all subsystems, and then
stops. For typical system configurations, this requires one or two hours.
■ Comprehensive testing – tests all subsystems repeatedly for up to 24 hours.
Since SunVTS software can run many tests in parallel and consume many system
resources, you should take care when using it on a production system. If you are
stress-testing a system using SunVTS software’s Comprehensive test mode, do not
run anything else on that system at the same time.
A server must be running the Solaris OS for SunVTS software to be able to test it.
Since SunVTS software packages are optional, they may not be installed on your
system. See
“To Find Out Whether SunVTS Is Installed” on page 4 for instructions.
5.1.1 SunVTS Software and Security
During SunVTS software installation, you must choose between Basic or Sun

security. Basic security uses a local security
file in the SunVTS installation directory to limit the users, groups, and hosts
permitted to use SunVTS software. Sun Enterprise Authentication Mechanism
security is based on the standard network authentication protocol Kerberos and
provides secure user authentication, data integrity and privacy for transactions over
networks.
If your site uses Sun Enterprise Authentication Mechanism security, you must have
Sun Enterprise Authentication Mechanism client and server software installed on
your network and configured properly in both Solaris and SunVTS software. If your
