Installation And Configuration Problems - IBM TS2900 Setup, Operator, And Service Manual

Isolating host attachment interface problems
After successfully exercising "Isolating drive problems" on page 134, and more specifically "Running
library verify diagnostic procedures" on page 73 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. If not already completed, run SAS Wrap Test from the Operator Panel. The test requires that a Wrap
tool is installed at some point during the test procedure.
a. If the wrap test fails, replace the library, and skip to Step 3.
b. Proceed to Step 2 if the wrap test passes.
2. Use the ITDT utility to evaluate connectivity from the HBA through the cabling to the drive. ITDT
does not require separate device drivers, thus the Operating System can scan, and find all the LTO
devices that are attached.
a. If ITDT cannot successfully locate the LTO drive, suspect cabling or HBA problems, and skip to
Step 4.
b. If ITDT successfully located the LTO drive, proceed to Step 3. See "The IBM Tape Diagnostic tool
(ITDT)" on page 139 for a brief description of ITDT and instructions on how to download the tool
from the web.
3. If ITDT successfully locates the LTO devices, 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 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 33.
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 9 and "Supported servers, operating
systems, and software" on page 12.
v Cable connections: Ensure that there are no bent pins on cables and that all connections are securely
fastened.
v SAS cables and interposers: Ensure that SAS cables and interposers (if any) are properly attached. See
"Connecting the Host Interface cables" on page 34.
v Backup application installation: Refer to the documentation included with your backup application
software for instructions on how to verify installation.
v 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 "Installation and configuration" on page 21 to determine whether a step was
missed or misread.
If you are still experiencing difficulty with installing or configuring your library, see "Contacting IBM
technical support" on page 139.
