Table 7. Diagnostic and Maintenance Functions (continued)
Function Code 6 - Run Wrap Test
Causes the drive to perform one of the following:
v
A check of the SCSI circuitry from and to the SCSI connector
v
A check of the Fibre Channel circuitry from and to the Fibre Channel connector or fiber cable
To run the test, determine whether your drive uses a SCSI or Fibre Channel interface, then choose one of the
following procedures.
Running a SCSI Wrap Test
This test evaluates the SCSI circuitry. A SCSI LVD wrap plug (part number 19P0481) is required for this procedure.
To order the wrap plug, see “Appendix A. Tools and Supplies” on page 81.
Before you select this function, terminate the SCSI bus and attach a SCSI wrap plug by doing one of the following:
v
Place a jumper on pins 5 and 6 of the drive’s SCSI ID connector (as shown by the shaded area in the figure
below), then attach the SCSI wrap plug to the connector (in place of the SCSI cable).
v
Place a jumper on pin 6 of the drive’s SCSI ID connector (as shown by the shaded area in the figure below), then
connect a Y-cable to the SCSI connector. Connect a terminator to one end of the Y-cable and connect the SCSI
wrap plug to the other end of the cable.

1. Ensure that the drive does not contain a cartridge.
2. Within a 1-second interval, press the unload button three times. The status light becomes solid amber, which
means that the drive is in maintenance mode.
Note: If a cartridge is in the drive, it will eject the first time that you press the unload button and the drive will not
be placed in maintenance mode. To continue placing the drive in maintenance mode, remove the cartridge and
repeat this step.
3. Press the unload button once per second until
6
appears in the single-character display.
Note: If you cycle past
6
, press the unload button once per second until it redisplays.
4. To select the function, press and hold the unload button for 3 seconds. After you select the function, the tape
drive automatically starts the test:
v
If the test is successful, it loops and begins again. Press the unload button. The test stops,
0
displays, and the
tape drive exits maintenance mode. To continue to isolate the problem, go to “Fixing SCSI Bus Errors” on
page 65 and locate the steps to take after you run the SCSI wrap test.
v
If the test fails,
8
displays, the test stops, and the tape drive exits maintenance mode. To resolve the error,
replace the tape drive (see “Removing the SCSI Tape Drive” on page 71).
