z If there were AIX error log entries, what the error log entries were, such as: TAPE_ERR1, TAPE_ERR6, etc..
z Be prepared to assist the support person to do further problem isolation and problem determination, including:
{ You have system access.
{ Have the tape drive test tape or diagnostic tape available.
{ Have the IBM cleaning tape available.
{ Have the failed data cartridges available.
{ Have a new IBM data cartridge available.
Tape Drive Self Test
Some tape drives have the ability to both test themselves and to test a data cartridge. This test is done entirely in the drive
with the status being reported by the drive LED's and or display on the tape drive.
200GB LTO2 Tape Drive Internal Self Test(IST)
The following procedure is designed to quickly perform a complete set of diagnostic internal self tests on the half-high
LTO-2 tape drive, without impacting server operation. This 5 = minute test can also be used to verify the status of individual
LTO tape cartridges.
Enter Diagnostic Mode:
1. Verify that a tape cartridge is not loaded in the drive. To unload a cartridge, press the eject button on the front of the
drive.
2. Press and hold the eject button for 7 seconds, until the green Ready LED starts flashing rapidly, then release the
button.
The Ready LED will continue flashing, indicating that the drive is waiting for a cartridge to be inserted.
Running the Self-Test:
3. Start the self-test by inserting IBM Test Tape P/N 24R0395 into the drive. If an IBM Test Tape is not available, you
can substitute a scratch (blank) LTO Ultrium-2 data cartridge.
Note:
!Important!
Use a blank cartridge that does not contain customer data. During this self-test, the cartridge will be rewritten with a
test pattern and any customer data will be destroyed.
Overall test duration is about 5 = minutes.
a. A cartridge must be loaded within 15 seconds -- otherwise, the drive will automatically revert back to normal
operation. If necessary, return to step 1 to re-enter diagnostic mode.
b. Use a cartridge that is not write-protected. If a write-protected cartridge is inserted while the drive is in
diagnostic mode, the cartridge will be ejected -- see step 9 below.
c. Self-testing can only be performed using a write-compatible (either Ultrium-1 or Ultrium-2) cartridge type, and
with a cartridge that is not damaged -- see step 9 below.
d. If a cleaning cartridge is inserted while the drive is in diagnostic mode, cleaning will occur and the drive will
then return to normal operating mode. To re-enter diagnostic mode, return to step 1.
4. At any time, self-testing can be stopped by pressing the eject button. After a current test operation is completed, the
cartridge will be ejected and the drive will return to normal operation.
5. While self-testing is in progress, the Ready LED will continue to flash. The following 4 test steps are performed: The
initialization sequence has an approximate duration of 20 seconds. The Activity LED indicates tape movement. The
hardware test has an approximate duration of 2 minutes. During that time, a static test is performed on the drives
electrical components, and proper operation of the cartridge load/unload mechanism is verified. The write/read test
has an approximate duration of 3 minutes. The Activity LED indicates tape movement.
Interpreting the Results:
6. Test Passed: When self-testing has completed successfully and no problems were detected, the cartridge is unloaded
