7.10 How to Use SunVTS Software

7.10.1 Before You Begin

If your system passes the firmware-based diagnostics and boots the operating system, yet does not function correctly, you can use SunVTS software, the Sun Validation and Test Suite, to run additional tests. These tests verify the configuration and functionality of most hardware controllers and devices.

You must have root or superuser access to run SunVTS tests and the system must be booted to the multiuser level (level 3). If you are not familiar with these or other basic UNIX commands and procedures, such as shutting down the system, booting the system, and configuring devices, you can find the information you need in the following sources:

• Solaris Handbook for Sun Peripherals

• AnswerBook2(TM) online documentation for the Solaris operating environment

• Other software documentation that you received with your system

7.10.2 What to Do

This procedure assumes that you will test your Sun Enterprise 220R server remotely by running a SunVTS session from a workstation using the SunVTS graphical interface. For information about other SunVTS interfaces and options, see "7.1 About Diagnostic Tools".

1. Use xhost to give the remote server access to the workstation display.

   On the system from which you will be running the SunVTS graphical interface, type:

   % /usr/openwin/bin/xhost + remote_hostname

   Substitute the name of the Sun Enterprise 220R server for remote_hostname. Among other things, this command gives the server display permissions to run the SunVTS graphical interface in the OpenWindows(TM) environment of the workstation.

2. Remotely log in to the server as superuser (root).

3. Check whether SunVTS software is loaded on the server.

   SunVTS is an optional package that may or may not have been loaded when the server software was installed. For more information, see "7.9 How to Check Whether SunVTS Software Is Installed".

4. To start the SunVTS software, type:

   # cd /opt/SUNWvts/bin # ./sunvts -display local_hostname:0

   Substitute the name of the server you are using for local_hostname. Note that /opt/SUNWvts/bin is the default /bin directory for SunVTS software. If you have installed SunVTS software in a different directory, use the appropriate path instead.

   When you start SunVTS software, the SunVTS kernel probes the test system devices. The results of this probe are displayed on the Test Selection panel. For each hardware device on your system, there is an associated SunVTS test.

5. Fine-tune your testing session by selecting only the tests you want to run.

   Click to select and deselect tests. (A check mark in the box indicates the item is selected.)

   

7.10.3 Results

If SunVTS tests indicate an impaired or defective part, see the procedures in this service manual or contact your qualified Sun service provider to replace the defective part.
