How to Use SunVTS Software
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, the Sun Validation and
Test Suite, to run additional tests. These tests verify the configuration and
functionality of most hardware controllers and devices.
You’ll need root or superuser access to run SunVTS tests.
What to Do
This procedure assumes you’ll 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 “About Diagnostic
Tools” on page 118.
1. Use the xhostcommand to give the remote server access to the local display. Type:
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™ environment of the workstation.
2. Remotely log in to the server as superuser or root.
3. Check whether SunVTS software is loaded on the server.
SunVTS software is an optional package that may or may not have been loaded
when the server software was installed. For more information, see “How to Check
Whether SunVTS Software Is Installed” on page 134.
