Tape Unit Self-Test Procedure
Introduction: The following procedure is designed to allow you to quickly
perform a complete set of diagnostic tests on a 4487 or 4587 (SLR100) tape unit,
without impacting iSeries 400 system operation. This test can also be used to verify
good performance of individual tape cartridges.
Enter Diagnostic Mode:
1. Verify that a cartridge is not loaded in the tape unit. To unload a cartridge,
press the eject button on the front of the tape unit. If the cartridge does not
eject, refer to “Tape Cartridge – Manual Removal” on page 701 of this Problem
Analysis Guide.
2. Press and hold the eject button for about 6 seconds, until the amber LED starts
flashing slowly, then release the button. The amber (left) LED will flash,
indicating that the tape unit is is waiting for a cartridge to be inserted.
Running the self-test:
3. Self-testing begins when a scratch data cartridge is inserted into the tape unit.
The Ready (left) LED will flash, indicating that self-testing is in progress.
Note: A cartridge must be loaded within 15 seconds -- otherwise, the tape unit
will automatically revert back to normal operation. If necessary, return to
step 1 to reenter diagnostic mode.
4. For fastest results, we recommend using an IBM SLR100 Test Tape (P/N
35L0967) which was originally provided with your iSeries 400 system.
Attention: 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.
Note: Use a cartridge that is not write-protected. If a write-protected cartridge
is inserted while the tape unit is in diagnostic mode, the cartridge will
be ejected -- see step 9 below.
Self-testing will only be performed using a write-compatible cartridge
type, and with a cartridge that is not damaged -- see step 9 below.
