Troubleshooting and Diagnostics
Usually, problems encountered during the installation of
your library are caused by improper SCSI bus configuration,
application software configuration errors or by an OS that
has not been correctly configured. If the application software
that you are attempting to use is not communicating with
your VLS DLT after installation, check the following:
4 SCSI IDs
Make sure that the IDs you selected for the robotics
and tape drive are not the same as the ID used by
any other SCSI device on that bus, including the
host SCSI adapter card.
4 SCSI Cabling
Verify that all SCSI cables are securely connected at
both ends and that the bail locks are secured. Also,
check the length and integrity of your SCSI cabling.
The total length of all SCSI cables must not exceed
19.7 feet (6.0 meters) for single-ended
configurations and 82 feet (25 meters) for
differential configurations. Try replacing suspected
cables with known good cables.
4 Termination
Check that all SCSI buses are properly terminated.
4 Compatibility
Ensure sure that your library and its tape drives are
compatible with the SCSI adapter card and
application software you plan to use.
4 SCSI Adapter Card Installation
Verify that you have installed your SCSI adapter
card correctly. Refer to the documentation that came
with your card for installation and troubleshooting
instructions. Pay particular attention to any steps
describing the settings of various jumpers and/or
