Datasheet

from the drive and all LEDs are off. Proper functioning of both the drive and the tape cartridge has been verified.
a. If the IST passes, then the tape drive has no hardware fault and no further drive tests are required.
b. Direct the customer to troubleshoot the SCSI bus, OS 1 software configuration to determine the cause of failure
c. Any other LED status requires that the IST is repeated with a different compatible data cartridge that is not
write-protected.
Note:
When the yellow Clean LED remains on, it indicates that self-testing has completed successfully -- but cleaning
is required. Clean the drive by inserting an IBM Cleaning Cartridge (P/N 35L2086). The drive is no longer in
diagnostic mode, and has been returned to normal operation.
7. Drive Failure: When a drive problem is detected, the cartridge will remain loaded inside the drive and the yellow Fault
LED ( ! ) will flash.
8. Media Failure: When a media problem is detected, the cartridge will remain loaded inside the drive, and the yellow
Clean LED will flash. Repeat self-test using another tape cartridge, and replace any defective media.
9. Incorrect cartridge: When the drive has determined that an incorrect tape cartridge was inserted, the cartridge is
unloaded and both the Activity and Clean LEDs will flash. Self-testing cannot be performed if the inserted cartridge is
one of the following:
{ Write-protected
{ Damaged
{ Media type that is not write-compatible with the drive
Press the eject button, to end self-test and return the drive to normal operating mode. Then return to step 1 and run the
self-test using a suitable cartridge.
10. Return to Normal Operation: Following a self-test failure, the tape cartridge will remain loaded inside drive, and the
drive will remain in diagnostic mode. Press the eject button to unload tape cartridge and return drive to normal
operation.
800GB LTO4 Tape Drive Self Test(IST)
This procedure is designed to allow you to quickly perform a complete set of diagnostic tests on your half-high LTO-4 tape
drive, without impacting server operation.
This 4-minute test can also be used to verify good performance of individual LTO tape cartridges.
Enter Diagnostic Mode:
1. Verify that a tape cartridge is not loaded in 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 all LEDs become active), then release the button.
3. The Ready LED will continue flashing, the Fault LED ( ! ) will remain on, and "1" will be flashing -- indicating that
the drive is in diagnostic mode and waiting for a cartridge to be inserted. Running the Self-Test:
4. Start the self-test by inserting a scratch (blank) LTO Ultrium-4 data cartridge. If an Ultrium-4 data cartridge is not
available, an Ultrium-3 cartridge can be substituted.
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 4 minutes.
Note:
a. A cartridge must be loaded within 15 seconds -- otherwise, the drive will automatically revert back to normal
operation. If necessary, return to step 2 to reenter 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-4 or Ultrium-3) 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, it will be ejected.
5. While self-testing is in progress, LEDs will remain active and the following test steps are performed:
