Run a Library Self Test
The library self-test moves a diagnostic cartridge between the reserve slot, storage
slots, drives, and the mail slot. 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 the latter case, proportional to
the size of the library.
To carry out a self test, proceed as follows:
1. Make sure that the library contains a diagnostic tape.
A diagnostic tape is a blank data tape that is labeled with a special DG volume
label. The label is included in the accessory kit that ships with the library. The
diagnostic tape must reside in a reserved slot or in any mail slot cell. For further
information, see
"Providing Diagnostic Cartridges" on page 6-2.
2. Make sure that the mail slot is closed and that all magazines are securely latched.
3. Make sure that at least one of the four cells in the standard mail slot is empty.
4. Make sure that at least one drive is free and can mount tapes.
5. Select Library from the menu on the left side of the interface.
The graphical library map appears.
6. Click the Library control at the top left of the graphical library map.
A context menu appears.
7. Select Run Self Test from the context menu.
A submenu appears.
8. Select Basic Self Test or Full Self Test from the submenu.
The dialog for the specified self test appears. It explains the scope of the test and
notes that the library will automatically go offline during the test. A basic test will
take a few minutes. A full test will take considerably longer.
9. To automatically bring the library back online at the end of the self test, check the
Set the Library back Online ... checkbox.
10. To run the specified test and close the dialog, press OK.
When the test completes, the result bar will display the number of moves
performed.
11. To close the dialog and skip the specified test, press Cancel.
12. To end a running test prematurely, click the Library control at the top left of the
Library screen. When the context menu appears, select Stop the current test.
It may take a short while for the test to stop.
13. If the diagnostic cartridge was not returned to its reserved cell at the end of the
test, move the diagnostic cartridge now.
