eject the scratch cartridge, and then the cartridge is moved back to the I/O
Station. The bar code is read again and compared with the value stored earlier.
3. When prompted, remove the scratch cartridge from the I/O Station.
The result of the test (PASSED or error message) is reported on the Operator
Panel.
4. View the Error Log to check if any errors occur.
If an error occurs, see Appendix B, “Error Codes,” on page B-1 to identify and
locate the problem.

Drive Diagnostics to run various drive-related
diagnostic tests.
To run drive diagnostic tests:
1.
Select Drive Diagnostics , and press Enter. Select one of the diagnostic tests and
follow the on-screen instructions.
2.
When prompted, insert a scratch (blank) cartridge into the I/O Station.
•
Normal Read/Write Test — Runs most of the tests that normally occur when
the library is powered ON (POST). When prompted, load a scratch cartridge to
run the calibrate drive, read/write, and tape motion tests. These tests calibrate
the read/write channel to optimum settings, run a long read/write test using
all servo positions, and exercise all of the tape motion functions of the drive.
Takes approximately 18 minutes.
• Perform Read/Write Test (Performance R/W Test) — Runs a shortened
version of the Normal R/W Test . It does not include the POST diagnostic,
calibrate drive, or unique tape motion tests. It checks the motors and head by
running read/write tests on a shortened section of tape, both inbound and
outbound. Takes approximately 4 minutes (if no error occurs) to 9 minutes (if
calibration is required).
• Media Test — Runs tests on a tape cartridge. When prompted, insert the
cartridge to test into the I/O Station. This test overwrites any data on the
cartridge. It runs read/write tests on the outer tracks of the tape to verify the
media tracking and performance. Takes approximately 9 minutes.
• Head Test — Runs read/write tests on the tape drive head. When prompted,
insert a scratch cartridge into the I/O Station. It runs read/write tests on the
inner tracks of the tape to verify the head performance. Takes approximately 6
minutes.
•
SAS Wrap Test
— Runs tests on the SAS interface SCSI controller. Remove the
SAS cable from the library and insert the SAS wrap tool (see Figure 4-28 on
