56 Troubleshooting and Diagnostics

Installation Problems

Usually, problems encountered during the installation of your Scalar 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 library after installation, check the following:

4 SCSI IDs

Make sure that the IDs you selected for the library robotics and tape drives 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

cables connected to a SCSI II bus must not exceed 9.85 feet (3.0 meters) for single-ended

configurations and 82 feet (25 meters) for differential configurations. Try replacing suspected

cables with known good cables.

Note

The length of the Scalar Library internal SCSI cables is 1 foot. This

length must be included in any calculations of cable length.

4 Termination

Check that all SCSI buses are properly terminated.

4 Compatibility

Ensure that your library and its tape drives are compatible with the SCSI adapter card and

application software you plan to use.

Note

For a list of compatible SCSI adapters and application software, call

adic’s Customer Assistance Center at (206) 883-HELP (4357).

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
