Scalar 24

Troubleshooting and Diagnostics

This chapter contains some general suggestions to aid you in solving problems.

Installation Problems

Usually, problems encountered during the installation of your Scalar 24 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 library after installation, check the following:
SCSI IDs:
SCSI Cabling:
Termination:
Compatibility:
SCSI Adapter Card
Installation:
NOTE: For a list of compatible SCSI adapters and application software, check with your
application software vendor.

Troubleshooting and Diagnostics
Make sure that the IDs you selected for the Scalar 24 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.
Verify that all SCSI cables are securely connected at both ends and
that the jack screws are secured. Also, check the length and integrity of
your SCSI cabling. The total length of a SCSI bus must not exceed 12
meters (39.4 feet). Replace suspect cables with known good cables.
NOTE: The length of the internal SCSI cabling inside your Scalar
24 is one foot for each drive. This length must be included in any
calculations of bus length.
Check that all SCSI buses are properly terminated.
Ensure that your Scalar 24 and its tape drive(s) are compatible with the
SCSI adapter card and application software you plan to use.
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 switches on the card.
Check that the card is seated fully in the I/O connector.
Refer to the documentation included with your software for instructions
on how to verify installation.
