Running Library Verify Diagnostics

Figure 4-26. Library Verify diagnostics
Use Service → Diagnostics → Run Library Verify to test the library and drive
hardware, communications, and the read/write capability of the library. Library
Verify is the most critical and most frequently used test, and should be executed after
all maintenance procedures to ensure correct library performance.
Note: Running the Library Verify diagnostic test will unload tape cartridges in the

functional. Then, the library tests communications with the tape drive over the
internal bus. 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.
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
