Several tests require media or loopback connectors. 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.
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.
