the accessor mechanism to be inoperable. Execute a Library System Test. See “Service Library:
Perform Diagnostics” on page 132 for the web or “Service: Run Tests” on page 103 for the OCP If the
problem is persistent, contact Dell technical support.
Isolating Web User Interface Problems
If the Web User Interface is not functioning at all or if it is intermittently functioning, review the
following steps to ensure that it is properly configured, or, to help determine which CRU or part needs to
be replaced. The complete Web User Interface electronics reside on the library controller card CRU.
1. Ensure that the ethernet cable is securely plugged in the rear of the library at the ethernet port. See
▌7▐ on the “Rear Panel” on page 3.
2. Ensure that the correct IP, Netmask, and Gateway addresses are keyed into the network parameters.
From the Operator Control Panel, navigate to Configure > Network.
3. Ensure that the correct IP address is being used on the web browser. If you get a security certificate
alert when logging in to the Web User Interface, you can install the certificate or allow an exception
(depending on the internet browser you are using). Even though with some browsers you will still
receive a security certificate warning/error each time you log in to the Web User Interface, your
transmission is secure. SSL is enabled when the URL to your library begins with https:// and some
browsers will show a lock.
4. If the ethernet connection is a direct connection between the PC and the library, a special "crossover"
ethernet cable needs to be used.
Note: On newer PCs, either straight through or crossover ethernet cables may be used since the
crossover requirement is provided internally.
5. Check the ethernet cable carefully (or try another cable) and, if the cable is connected to a network
hub or switch, try a different port.
6. If the Web User Interface is still malfunctioning, replace the Library Controller Card CRU (refer to
“Replacing a Library Controller Card” on page 187).
Isolating Accessor 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 scanner (library enclosure CRU) needs to be replaced.
1. Ensure that a supported bar code label (or labels) are being used.
2. With library power OFF, reseat the library controller card CRU (refer to “Replacing a Library
Controller Card” on page 187), 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, please contact Dell technical support.
Isolating Host Attachment Interface Problems
After successfully exercising "Isolating Drive Sled Problems", and more specifically the "Library Verify"
diagnostic on the Operator Control Panel (Service > Library Verify) which includes a drive (or drives)
read/write diagnostic, the following procedures are suggested to help isolate the failure to properly
establish connectivity to the Host Bus Adapter (HBA).
1. Use the utility, ITDT, to evaluate connectivity from the HBA through the cabling to the drive (or
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. If ITDT cannot successfully locate the LTO drive,
suspect cabling or HBA problems, and skip step 2. If ITDT successfully located the LTO drive,
proceed to step 2. See “Using the ITDT Firmware Update, Dump Retrieval and Drive Test Tool ” on
page 177 for a brief description of ITDT and instructions on how to download the tool from the web.
