Exercising The System Using The Hardware Diagnostic Suite - Sun Microsystems Sun Fire V440 Diagnostics And Troubleshooting Manual

These documents are available on the Solaris Supplement CD and on the Web at:
http://www.sun.com/documentation. You should also consult the SunVTS
README file located at /opt/SUNWvts/. This document provides late-breaking
information about the installed version of the product.
SunVTS Software and Security
During SunVTS software installation, you must choose between Basic or Sun
Enterprise Authentication Mechanism (SEAM) 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. SEAM security is based on Kerberos—the
standard network authentication protocol—and provides secure user authentication,
data integrity, and privacy for transactions over networks.
If your site uses SEAM security, you must have the SEAM client and server software
installed in your networked environment and configured properly in both Solaris
and SunVTS software. If your site does not use SEAM security, do not choose the
SEAM option during SunVTS software installation.
If you enable the wrong security scheme during installation, or if you improperly
configure the security scheme you chose, you may find yourself unable to run
SunVTS tests. For more information, see the SunVTS User's Guide and the
instructions accompanying the SEAM software.
Exercising the System Using the Hardware
Diagnostic Suite
The Sun Management Center product features the optional Hardware Diagnostic
Suite, which you can purchase as an add-on. The Hardware Diagnostic Suite is
designed to exercise a production system by running tests sequentially.
Sequential testing means the Hardware Diagnostic Suite has a low impact on the
system. Unlike SunVTS software, which stresses a server by consuming its resources
with many parallel tests (see "Exercising the System Using SunVTS Software" on
page 40), the Hardware Diagnostic Suite lets the server run other applications while
testing proceeds.
When to Run the Hardware Diagnostic Suite
The best use of the Hardware Diagnostic Suite is to disclose a suspected or
intermittent problem with a noncritical part on an otherwise functioning server.
Examples include questionable disk drives or memory modules on a server that has
ample or redundant disk and memory resources.
