Intervention

Certain tests require that you intervene before such tests can be selected. These tests require you to load test media or install loopback connectors, and enable the intervention mode before the tests can be selected.

You must install media in these devices if you plan to test them in Functional mode:

• Tape drive--load a scratch tape in the tape drive that you plan to test. The tape test has a Read-only mode, but use a scratch tape to avoid inadvertently writing over data.

• CD-ROM drive--load a compact disc (CD) into the drive. It can be an audio or data CD.

• Diskette drive--load a scratch diskette in the drive. The diskette test has a Read-only mode, but use a scratch tape to avoid inadvertently writing over data.

• Communication ports--many of these tests require a loopback connector attached to the port. Attach any required loopback connectors for the ports you plan to test. For more information about loopback connectors refer to the SunVTS 3.0 Test Reference Manual.

Install such requirements before the SunVTS kernel probes for devices (when SunVTS is started, or the reprobe function is run) to allow the SunVTS kernel to properly identify each device.

Intervention mode serves as a reminder that you may need to intervene before running certain tests; it does not verify that the appropriate test media or loopback connectors have been installed.

The location of the Intervention mode button varies based on the SunVTS interface that you are using. For specific details refer to:

• CDE interface--"CDE Device Selection Region"

• OPEN LOOK interface--"The Select Tests Button"

• TTY interface--"Setting TTY Options"
