Drive Diagnostics to run various drive-related
diagnostic tests.
To run drive diagnostic tests:
1. Log into the Operator Panel.
2. Press the Down button to select Service Mode , and press Enter.
3. Press the Down button to select Diagnostics , and press Enter.
4. Select Drive Diagnostics , and press Enter. Select one of the following diagnostic
tests and follow the on-screen instructions.
5. When prompted, insert a scratch cartridge into the I/O Station.
•
Normal R/W Test — Runs a shortened version of the Performance 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).
• Perform. R/W Test (Performance R/W Test) — Runs most of the tests that
normally occur when the library is powered ON (POST). When prompted,
load a CE 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 up to 30 minutes.
• Media Test — Runs tests on the tape cartridge media. When prompted, insert
the cartridge to test into the I/O Station. This test overwrites any data on the
tape 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 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.
• Fibre Wrap Test — Runs tests on the fibre channel through the fibre channel
wrap plug.
Note: Fibre Wrap Plugs must be installed in both Fibre Channel ports on the
drive sled in order for the wrap test to run successfully.
6. Check the result of the test (PASSED or FAILED) reported on the Operator Panel.
