Function Code 6: Run Host Interface Wrap Test - IBM TS2280 Setup, Operator, And Service Manual

v If the copy operation completes successfully, the tape drive rewinds and unloads the tape, and exits
Maintenance mode after the cartridge is removed.
v If the copy operation fails, an error code displays in the SCD. To determine the error, locate the
code in Table 17 on page 65. The tape drive unloads the tape cartridge and exits Maintenance mode
after the cartridge is removed.

Function code 6: Run host interface wrap test

Approximate Run Time = 10 seconds per loop
Number of Loops = This test runs until stopped by pressing Unload.

Function code completes a check of the host interface circuitry and host connector on the drive.
1. Make sure that the host interface wrap plug is connected to the host interface connector at the rear of
1
the drive .
v Connect the wrap plug to the SAS port to be tested.
2. Place the drive in Maintenance mode. For instructions, see "Entering Maintenance mode" on page 23.
3. Press Unload once per second until

a. Index through the Maintenance mode options until
b. Press and hold Unload for 3 seconds to select Function code
c. After Function code
d. Press Unload within 5 seconds to make a different selection. If no other selection is made, the
drive completes option
4. Continue to press Unload once per second to cycle through the following functions:

v - : test the secondary SAS port
6 3
v - : test both primary and secondary SAS ports at the same time (requires a wrap plug in
2
both ports)
6 0
v - : exit
5. Press and hold Unload for three or more seconds, then release it to select one of the functions. The
drive automatically starts the test. If you cycle past the wanted code, press Unload once per second
until the code reappears.
6. The SCD displays a flashing
v If no error is detected, the diagnostic test loops and begin again. To stop the loop, press Unload for
1 second and release. When the loop ends,
exits Maintenance mode.
v If an error is detected, the Fault light flashes and the drive posts an error code to the SCD. To
determine the error, locate the code in Table 17 on page 65. To clear the error either turn the power
off and then on again, or reboot the drive by pressing and holding Unload for 10 seconds.
