agent.

The tape library is physically abused or used in a manner that is inconsistent with the operating

instructions or product specification defined by the manufacturer.

The tape library fails because of accident, misuse, abuse, neglect, mishandling, misapplication, alteration,

faulty installation, modification, or service by anyone other than the factory service center or its approved

agent.

The tape library is repaired by anyone, including an approved agent, in a manner that is contrary to the

maintenance or installation instructions supplied by the manufacturer.

3 Troubleshooting

This chapter provides information for verifying correct installation and troubleshooting the library.

Installation problems3.1

Problems encountered during the installation of the library are usually caused by improper SCSI bus configuration,

application software configuration errors, or an incorrectly configured operating system.

If the used application software is not communicating with the library after installation, check the following:

SCSI ID3.1.1

The library uses a single SCSI ID. Depending on other devices attached to the same SCSI bus and their SCSI IDs,

change the SCSI ID of the library or tape drive before use the library.

Review the manuals for the other devices on the SCSI bus or the operating system to determine which SCSI IDs are

currently in use.

SCSI host adapter installation3.1.2

1. Verify that the SCSI host adapter is installed correctly.

Refer to the manual that came with the SCSI host adapter for installation and troubleshooting instructions.

2. Pay particular attention to any steps describing the settings of various jumpers and/or switches on the host adapter,

if applicable.

3. Make sure that the host adapter is properly seated in the motherboard slot and the operating system correctly detects

the host adapter.

4. Make sure that the proper device driver is installed for the SCSI host adapter.

LUN scanning3.1.3

Use dual LUNs to control the tape drive (LUN 0) and library robotic (LUN 1). These models require an HBA that

supports LUN scanning and LUN scanning must be enabled.

SCSI cabling3.1.4

1. Verify that all SCSI cables are securely connected at both ends.

2. Check the length and integrity of the SCSI cabling.

3. Check the SCSI connector for bent pins.

The length of the internal SCSI cabling inside the library is 2 feet (60 cm). This length must be included in any

calculations of cable length.

•For LVD SCSI the maximum length for a single device is 82 feet (25 meters).

•For multiple devices, the maximum combined internal/external length is 40 feet (12 meters).

•If you have a combination of LVD and SE devices on the bus, the maximum cable length reverts to the SE

specification, which for ultra devices is 10 feet (3 meters) for four or fewer devices, and 5 feet (1.5 meters) for

more than four devices.

Termination3.1.5

If the library is the only SCSI device — other than the SCSI host adapter — on the selected SCSI bus, it must be

terminated. Likewise, if the library is physically the last SCSI device on the SCSI bus, it must be terminated.

Only the devices physically located at the beginning and end of the SCSI bus should be terminated.

Refer to the manuals supplied with other devices on the SCSI bus for information on enabling or disabling termination

on those devices.

NEO S-Series User Guide

If available, take the terminator from the accessories bag. The supplied terminator is “dual mode” and will work on both

Low-Voltage Differential (LVD) and Single Ended (SE) SCSI buses.

To terminate the library, see Chapter Connecting the parallel SCSI cable, Page Error! Bookmark not defined..

Check all SCSI and power connections and confirm that the library is attached to a valid SCSI SE or LVDS bus.

Compatibility3.1.6

Ensure that the library is compatible with the SCSI host adapter and backup application you plan to use. For a list of

compatible SCSI adapters and application software, check with your SCSI host adapter manufacturer or backup

application vendor.

NOTE

The host bus adapter for the library should be SCSI-3 LVDs. A

single-ended SCSI host bus adapter will severely degrade

performance. Also, if there is any SE devices on the same SCSI bus,

the entire SCSI bus will negotiate down to SE speed and severely

degrade performance

Backup application installation3.1.7

Refer to the documentation included with your backup application for instructions on how to verify proper installation.

Some backup software packages require an additional module to communicate with the library robotics.

Device driver installation3.1.8

Make sure that the proper device driver, if applicable, is installed for the library. Contact your support representative for

more information

NOTE

Many backup applications use their own drivers for the library and

tape drive. Before installing a driver, make sure it will not be in

conflict with the software.

Troubleshooting table3.2

Problem

Solution

Poor throughput performance

•Try a new tape. A marginal tape can cause performance problems due to

bad spots on the tape requiring retries.

•Backing up data that compresses poorly or is already compressed will

lower performance.

•Check the size of the files. Small file size can impact performance.

•Confirm that the backup application is utilizing block sizes of at least

32KB, preferably 64KB. Refer to the backup application documentation

for details.

•Check the network bandwidth from the host computer. If you are backing

up data over a network, consider comparing to a local-only backup.

•Make sure the backup server has enough memory to handle the bandwidth

of the backup or restore.

•Clean the tape drive with:

OCP, see Chapter Cleaning tape drives, Page Error! Bookmark not

defined..

RMU, see Chapter Cleaning tape drive(s), Page Error! Bookmark not

defined..

Cleaning

Cannot load the cleaning

cartridge •Make sure you are using an Ultrium universal cleaning cartridge.

See Chapter Tape cartridge type, Page Error! Bookmark not defined..

•Contact your service representative.

Device Not Detected on SCSI Bus

Connected to a high voltage

differential SCSI bus/host

adapter

•Attach device to a LVDS SCSI host adapter/bus.

•SCSI cable length exceeded, use shorter cable, or removes other devices

from the bus.

•Check for conflicting SCSI IDs.

•Check that the HBA supports LUN scanning and this feature is enabled.

•Device not properly terminated. See Chapter Termination, Page 8.

•Power up device before powering up the host computer.

•Check that the device has been powered up and is not in an error state.

•Check the SCSI connector for bent pins.
