Several tests require the installation of media or loopback connectors. You have to complete all installation requirements before the Oracle VTS kernel probes for devices (for example, when the software is started, or when you run the reprobe command). This installation allows the Oracle VTS kernel to properly identify each device.
You must install media in the following devices if you plan to test them in the System Exerciser test mode:
CD-ROM and DVD drives: Load the appropriate media into the drive. The media can be an audio or data CD.
I/O 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 connectors, see Connectors.
Printer ports: Requires a connection to a printer.
