 Performing a Library Self Test

The library has a self-test feature that exercises all of the library’s capabilities and can thus assist with fault isolation and validation of repair actions. The self-test moves a diagnostic cartridge between the reserve slot, storage slots, drives, and mailslot. A Basic Self Test performs seven moves. A Full Self Test moves the diagnostic tape to every empty slot in the library and performs a get/put to every occupied slot. The exact number of moves is, in this case, proportional to the size of the library.

This test is done through the SL150 front Op Panel.

To carry out a self test, proceed as follows:

Run a Library Self Test
1. If you have not already done so, take the library offline.
2. Select Library from the menu on the left side of the interface. The graphical library map appears.
3. Click the Library control at the top left of the Library screen.
4. Select Run Self Test from the Library control’s context menu.
5. Select Basic Self Test or Full Self Test from the menu. A basic test will take a few minutes. A full test will take considerably longer.
6. To run the specified test, press OK when the confirmation bar appears at the top of the screen. When the test completes, the result bar will display the number of moves performed. Press OK to close the result bar.
7. To skip the test press Cancel.
8. To end a running test prematurely, press the Stop the Test button that appears after the test starts. It may take a short while for the test to stop. When it does, press OK.
9. If the diagnostic cartridge was not returned to its reserved cell at the end of the test, move the diagnostic cartridge now. 

See Storagetek SL150 Modular Tape Library System User Guide E24606-01 for full details.

Note: The SL150 utilizes stepper motors rather than tachometer count motors. The diagnostic self test routine assists these motors to dial in and should be run once after initial installation. This is not noted in the installation manual but is advised.
