6. If the host tool, ITDT, cannot detect the drive or library, look for problems with the host interface
cabling, the HBA, the device driver, or the backup application software.
Isolating Web User Interface problems
1. Verify that you entered the account name and password correctly. The account name and password
are case-sensitive.
2. Verify that other library users are not entering commands from the Web User Interface or Operator
Panel at the same time you are issuing commands.
3. Ensure that library firmware is at the latest level (visit http://www.dell.com/support).
4. Ensure that the Ethernet cable is securely plugged in the rear of the library at the Ethernet port.
5. Ensure that the correct IP, netmask, and gateway addresses are keyed into the network parameters.
6. Ensure that the correct IP address is being used on the web browser.
7. If the Ethernet connection is a direct connection between the PC and the library, a special "crossover"
Ethernet cable is required.
Note: On newer PCs, either straight through or crossover Ethernet cables might be used since the
crossover requirement is provided internally.
8. 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.
9. If the Web User Interface is still malfunctioning, refer to “Contacting Dell technical support” on page
117.
Isolating host attachment interface problems
After successfully exercising “Isolating drive problems” on page 111, and more specifically “Running
library verify diagnostic procedures” on page 65 from the Operator Panel (Service > Library Verify), the
following procedures are suggested to help isolate the failure to properly establish connectivity to the
Host Bus adapter (HBA).
1. Use the ITDT-DCR utility to evaluate connectivity from the HBA through the cabling to the drive.
ITDT-DCR does not require separate device drivers, thus the Operating System can scan, and find all
the LTO devices that are attached.
a. If ITDT-DCR cannot successfully locate the LTO drive, suspect cabling or HBA problems, and skip
to Step 4.
b. If ITDT-DCR successfully located the LTO drive, proceed to Step 3. See “ITDT-SE” on page 117 for
a brief description of ITDT-DCR and instructions on how to download the tool from the web.
2. If ITDT-DCR successfully locates the LTO devices, verify that the correct application device drivers
and backup application software is properly installed.
3. Ensure that all the required or latest available Operating System files or updates (DLLs, PTFs) are
installed and applied.
Installation and configuration problems
Problems that are encountered during the installation of the library are caused by improper application
software configuration errors or an incorrectly configured operating system. If the application software
that you are using is not communicating with the library after installation, check:
v Accessor locking screw: Ensure that the accessor locking screw on the rear panel of the library is
removed before the library is powered ON. See “Removing the accessor locking screw” on page 28.
v HBA LUN 0/1 support: A single ID addresses both drive and library since the drive is LUN 0 and the
library is LUN 1. These models require an HBA that supports LUN scanning, which must be enabled
at the HBA. See “Logical Unit Number (LUN) scanning” on page 8.
v Cable connections: Ensure that there are no bent pins on cables and that all connections are securely
fastened.
