SCSI External Wrap Test The following SCSI External Wrap Test is for both the FC 2/1 LV and the FC 4/ 1 HV bridges. When performing the SCSI External Wrap Test, the following prompts appear: Number of Test Iterations (1-10000 or Forever (F)): ■ Entering [F] or an integer in the range of 1 to 10,000 sets the number of times the test will repeat - the smaller the number, the quicker the test will reach completion. Initiator SCSI Port # (0-3): ■ Enter the port number for the port that will serve as the Initiator during the wrap test. On the FC 4/1 HV, the port number is the same as the bus number. On the FC 2/1 LV, be sure the bus of the designated port is externally terminated. Target SCSI Port # (0-3): ■ Enter the port number for the port that will serve as the Target during the wrap test. The port number designated here should not be the same port number as designated for the Initiator SCSI port. On the FC 4/1 HV, the port number is the same as the bus number. For the SCSI wrap test, it does not matter which port (or bus, for the FC 4/1 HV) is designated the Initiator and which is designated the Target. Both ports (or buses, for the FC 4/1 HV) will be tested. After entering values for the above prompts, connect the SCSI ports with the wrap cable. Be sure to use the correct SCSI cable type for the type of SCSI ports (or buses, for the FC 4/1 HV) (LVD/SE or HVD). When the SCSI wrap cable is securely attached to both ports (or buses, for the FC 4/1 HV), press the [Enter] key as indicated in the Diagnostics menu to begin the test. For iterative tests, the results 'PASSED' or 'FAILED' will be displayed upon completion of the test. For tests set to run forever, results will be displayed only in the event of a failure. If a failure does occur, the address of the failure will be displayed. Otherwise, disconnect the SCSI wrap cable to end a forever test. This should result in a failure message (since the cable is disconnected) and the test will end. If no failure message appears when the SCSI wrap cable is disconnected during the wrap test, then there likely is a problem. Refer to Chapter 8, Troubleshooting for assistance.
