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 111 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 les or updates (DLLs, PTFs) are
installed and applied.
Installation and conguration problems
Problems that are encountered during the installation of the library are caused by improper application
software conguration errors or an incorrectly congured operating system. If the application software
that you are using is not communicating with the library after installation, check:
• 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.
• 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 9
.
• Cable connections: Ensure that there are no bent pins on cables and that all connections are securely
fastened.
• SAS cables and interposers: Ensure that SAS cables and interposers (if any) are properly attached. See
“Connecting the Host Interface cables” on page 28.
• Backup application installation: Refer to the documentation included with your backup application
software for instructions on how to verify installation.
• Device driver installation: Ensure that the correct device driver, if applicable, is installed for the library.
Note: Many backup applications use their own drivers for the library and drive. Before a driver is installed,
make sure that it is not in conflict with the software. Contact your backup application vendor for this
information.
Review the information in Chapter 3, “Installation and conguration,” on page 21 to determine whether a
step was missed or misread.
If you are still experiencing difculty with installing or conguring your library, see “Contacting Dell
technical support” on page 111.
Important: Do not disassemble the library. The warranty on your library is voided if the unit is
disassembled without the approval of Dell Technical Support.
Interpreting front panel LEDs
Light emitting diodes (LEDs) on the front panel of the library provide a visual indication about the status of
certain library components. The LEDs can communicate that a problem exists when operator
interventions cannot.
