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
drives if the host application has not already done so.
To run library verification 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
Library Verify
, and press Enter. Follow the on-screen instructions.
The library performs a Power ON Self Test (POST), the normal test sequence
performed when the library is turned ON, to ensure that the library hardware is
functional. Then, the library tests communications with the tape drives over the
internal bus. If there is a cartridge in a drive, the library moves the cartridge to its
home slot, or to the I/O Station if the home slot is not known.
5.
When prompted, insert a scratch cartridge into the I/O Station.
When the scratch cartridge is loaded, the bar code reader reads the bar code label
on the cartridge and stores it for later comparison. The cartridge is then moved to
the tape drive, where the drive runs its own write/read/verify test. The cartridge
is then moved to the second drive, if installed, and the test is repeated. When the
test is done, the library tells the drive to eject the 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.
6.
Check the result of the test (PASSED or FAILED) reported on the Operator Panel.
7.
Press any key and, when prompted, remove the cartridge used for this diagnostic
from the I/O Station.
8.
View the
Error Log
to check if any errors occur.
