Using SunVTS Diagnostic Software

C H A P T E R 2

This chapter contains information about the SunVTS trademark diagnostic software tool.

Running SunVTS Diagnostic Tests

The servers are shipped with a Bootable Diagnostics CD that contains the Sun Validation Test Suite (SunVTS) software.

SunVTS provides a comprehensive diagnostic tool that tests and validates Sun hardware by verifying the connectivity and functionality of most hardware controllers and devices on Sun platforms. SunVTS software can be tailored with modifiable test instances and processor affinity features.

The following tests are supported on x86 platforms:

CD DVD Test (cddvdtest)

CPU Test (cputest)

Cryptographics Test (cryptotest)

Disk and Diskette Drives Test (disktest)

Data Translation Look-aside Buffer (dtlbtest)

Emulex HBA Test (emlxtest)

Floating Point Unit Test (fputest)

InfiniBand Host Channel Adapter Test (ibhcatest)

Level 1 Data Cache Test (l1dcachetest)

Level 2 SRAM Test (l2sramtest)

Ethernet Loopback Test (netlbtest)

Network Hardware Test (nettest)

Physical Memory Test (pmemtest)

QLogic Host Bus Adapter Test (qlctest)

RAM Test (ramtest)

Serial Port Test (serialtest)

System Test (systest)

Tape Drive Test (tapetest)

Universal Serial Board Test (usbtest)

Virtual Memory Test (vmemtest)

SunVTS software has a sophisticated graphical user interface (GUI) that provides test configuration and status monitoring. The user interface can be run on one system to display the SunVTS testing of another system on the network. SunVTS software also provides a TTY-mode interface for situations in which running a GUI is not possible.

Diagnosing Server Problems With the Bootable Diagnostics CD

SunVTS 6.4 or later software is preinstalled on your server. The server is also shipped with the Bootable Diagnostics CD. This CD is designed so that the server will boot from the CD. This CD boots and starts SunVTS software. Diagnostic tests run and write output to log files that the service technician can use to determine the problem with the server.

Requirements

To use the diagnostics CD you must have a keyboard, mouse, and monitor attached to the server on which you are performing diagnostics, or available through a remote KVM.

Using the Bootable Diagnostics CD

To use the diagnostics CD to perform diagnostics:

1. With the server powered on, insert the CD into the DVD-ROM drive.

2. Reboot the server, and press F2 during the start of the reboot so that you can change the BIOS setting for boot-device priority.

3. When the BIOS Main menu appears, navigate to the BIOS Boot menu.

Instructions for navigating within the BIOS screens appear on the BIOS screens.

4. On the BIOS Boot menu screen, select Boot Device Priority.

The Boot Device Priority screen appears.

5. Select the DVD-ROM drive to be the primary boot device.

6. Save and exit the BIOS screens.

7. Reboot the server.

When the server reboots from the CD in the DVD-ROM drive, the Solaris Operating System boots and SunVTS software starts and opens its first GUI window.

8. In the SunVTS GUI, press Enter or click the Start button when you are prompted to start the tests.

The test suite will run until it encounters an error or the test is completed.

Note - The CD will take approximately nine minutes to boot.

9. When SunVTS software completes the test, review the log files generated during the test.

SunVTS provides access to four different log files:

SunVTS test error log contains time-stamped SunVTS test error messages. The log file path name is /var/opt/SUNWvts/logs/sunvts.err. This file is not created until a SunVTS test failure occurs.

SunVTS kernel error log contains time-stamped SunVTS kernel and SunVTS probe errors. SunVTS kernel errors are errors that relate to running SunVTS, and not to testing of devices. The log file path name is /var/opt/SUNWvts/logs/vtsk.err. This file is not created until SunVTS reports a SunVTS kernel error.

SunVTS information log contains informative messages that are generated when you start and stop the SunVTS test sessions. The log file path name is /var/opt/SUNWvts/logs/sunvts.info. This file is not created until a SunVTS test session runs.

Solaris system message log is a log of all the general Solaris events logged by syslogd. The path name of this log file is /var/adm/messages.

a. Click the Log button.

The Log file window is displayed.

b. Specify the log file that you want to view by selecting it from the Log file window.

The content of the selected log file is displayed in the window.

c. With the three lower buttons you can perform the following actions:

Print the log file - A dialog box appears for you to specify your printer options and printer name.

Delete the log file - The file remains on the display, but it will not be available the next time you try to display it.

Close the Log file window - The window is closed.

Note - If you want to save the log files: When you use the Bootable Diagnostics CD, the server boots from the CD. Therefore, the test log files are not on the server’s hard disk drive and they will be deleted when you power cycle the server. To save the log files, you must save them to a removable media device or FTP them to another system.
