Isolating Bar Code Scanner Problems

If the server has reported inventory problems relating to inability to read bar code labels,
or, if some or all of the cartridge labels are not being displayed on the Web User Interface,
use the following procedure to determine if the bar code scanner needs to be replaced (by
replacing the library chassis CRU).
1. Ensure that supported bar code labels are being used. Also, check for damaged
labels.
2. With library power OFF, reseat the library controller card, and then switch
library power ON.
3. Perform a re-inventory via the Operator Control Panel (Control > Re-Inventory) and
view the inventory via the Web User Interface (Monitor Library > Inventory) to
determine if the labels are now being read.
4. If the labels are still not being read properly, replace the library chassis.

Isolating Host Attachment Interface Problems

After successfully exercising
specifically the Library Verify diagnostic on the Operator Control Panel (Service > Library
Verify) which includes a drive read/write diagnostic, the following steps are suggested to
help isolate the failure to properly establish connectivity to the Host Bus Adapter (HBA).
1. If not already performed, exercise the drive interface wrap test on the Operator
Control Panel (Service > Service > Drive Tests). The test will require that a proper
Wrap Tool be installed at some point during the test procedure.
• If the wrap test fails, replace the drive sled, and skip to
• If the wrap test passes, continue with
2. Using the ITDI utility, evaluate connectivity from the HBA through the cabling to
the drives.
ITDT does not require separate device drivers, thus the Operating System has the
ability to scan and find all the LTO devices that are attached. See
Diagnostic Tool (ITDT)" on page 9-2
on how to download the tool from the Overland web site.
• If ITDT cannot successfully locate the LTO drive, suspect that there are cabling
• If ITDT successfully located the LTO drive, proceed to
3. Verify that the correct application device drivers and backup application software
is properly installed.
4. Ensure that all the required or latest available Operating System files and/or
updates (DLL's, PTF's, and so forth) have been installed and applied.

Identifying a Suspect Cartridge

The amber Attention LED will be lit on the front panel of the library when there has been a
failure that indicates a piece of media is bad, marginal, or invalid. It will be cleared when
all invalid cartridges have been exported from the library.
NOTE: The Attention LED may also be lit because a power supply, or a power supply fan is failing.
