SunVTS Software Overview

The SunVTS 5.1 Patch Set 5 (PS5) software, and future compatible versions, are supported on the Netra 240 server.

The SunVTS software, the Sun Validation Test Suite, is an online diagnostics tool for verifying the configuration and functionality of hardware controllers, devices, and platforms. It runs in the Solaris OS and has the following interfaces:

Command-line interface (CLI)

Serial (tty) interface

The SunVTS software suite performs system and peripherals stress testing. You can view and control a SunVTS software session over a network. Using a remote machine, 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 test modes:

Connection mode verifies the presence of device controllers. This typically takes no more than a few minutes and is a good way to run a "sanity check" on the 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. For instructions, see To Determine Whether SunVTS Software Is Installed.

SunVTS Tests

You can use the SunVTS software to view and control testing sessions on a remotely connected server. TABLE 2-1 lists some of the tests that are available.

TABLE 2-1 SunVTS Software Tests
SunVTS Software Test	Description
cputest	Tests the CPU.
disktest	Tests the local disk drives.
dvdtest	Tests the DVD-ROM drive.
n240atest	Tests the alarm card for alarm relays, LEDs, and FRU ID.
fputest	Tests the floating-point unit.
nettest	Tests the Ethernet hardware on the system board and the networking hardware on any optional PCI cards.
netlbtest	Performs a loopback test to check that the Ethernet adapter can send and receive packets.
pmem	Tests the physical memory (read only).
sutest	Tests the server's on-board serial ports.
vmem	Tests the virtual memory (a combination of the swap partition and the physical memory).
env6test	Tests the environmental devices.
ssptest	Tests ALOM hardware devices.
i2c2test	Tests I²C devices for correct operation.

SunVTS Software and Security

During SunVTS software installation, you must choose between basic or Sun Enterprise Authentication Mechanism trademark (SEAM) security. Basic security uses a local security file in the SunVTS software installation directory to limit the users, groups, and hosts permitted to use SunVTS software. SEAM 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 SEAM security, you must have the SEAM client and server software installed in your networked environment and configured properly in both Solaris software 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 choose, you may find yourself unable to run SunVTS software tests. For more information, see the SunVTS User's Guide and the instructions accompanying the SEAM software.

To Determine Whether SunVTS Software Is Installed

Type:

# pkginfo -l SUNWvts

If SunVTS software is loaded, information about the package is displayed.

If SunVTS software is not loaded, you see the following error message:

ERROR: information for "SUNWvts" was not found

Installing SunVTS Software

By default, the SunVTS software is not installed on the Netra 240 server. However, it is available on the Solaris OS supplement CD, and the latest revisions can be downloaded from the following web site:

http://www.sun.com/oem/products/vts/

Note - The SunVTS 5.1 Patch Set 5 (PS5) software, and future compatible versions, are supported on the Netra 240 server.

To find out more about using SunVTS software, refer to the SunVTS documentation that corresponds to the Solaris software release that you are running. You can also find additional information about the SunVTS software, as well as installation instructions, on the above web site.

Viewing SunVTS Software Documentation

The SunVTS Software documents are included on the software supplement CD that is part of each Solaris media kit release. These documents are also available at http://docs.sun.com.

For further information, you can also consult the following SunVTS software documents:

SunVTS User's Guide explains how to install, configure, and run the SunVTS diagnostic software.

SunVTS Quick Reference Card provides an overview of how to use the SunVTS interface.

SunVTS Test Reference Manual provides details about each individual SunVTS test.
