Running Drive Diagnostic Procedures; Drive Diagnostic Procedures - IBM TS2900 Setup, Operator, And Service Manual

Note: If the host application hasn't already unloaded tape cartridges in the drives, run the Library Verify
diagnostic test.
To run library verification diagnostic tests:
1. Select Run Library Verify, and press Enter. Follow the on-screen instructions. If there is a cartridge in
the drive, the library moves the cartridge to its home position, or to the I/O station if the home
position is not known.
2. When prompted, insert a scratch cartridge into the I/O station.
When the scratch cartridge is loaded, an inventory is conducted and the bar code reader reads the bar
code label on the cartridge and stores it for later comparison. The scratch cartridge is then moved to
the tape drive, where the drive runs its own write/read/verify test. When the test is done, the library
tells the drive to 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 for errors.
If an error occurs, see Appendix B, "Error codes," on page 187 to identify and locate the problem.

Select Service > Diagnostics > 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.
v 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).
v 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 with all servo positions, and exercise all of the tape motion
functions of the drive. Takes up to 30 minutes.
v 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 78 on page 75) into the SAS host connector. Start
the SAS wrap test. If the wrap test fails, contact your next level of support.
