Troubleshooting And Diagnostics; Installation Issues - ADIC FastStor 2 User Manual

This section contains information on troubleshooting and diagnosing your autoloader.

Installation Issues

Problems encountered during the installation of the autoloader are usually caused by improper
SCSI bus configuration, application software configuration errors, or by an incorrectly configured
operating system. If the application software that you are using is not communicating with the
autoloader after installation, check the following:
• SCSI ID—The autoloader uses one SCSI ID for the tape drive and one SCSI ID for the
autoloader robotics. Depending on other devices attached to the same SCSI bus and their
SCSI IDs, you may need to change the SCSI ID of the autoloader or tape drive before you
can use the autoloader. Review the manuals for the other devices on the SCSI bus or your
operating system to determine which SCSI IDs are currently in use. See
Changing the SCSI IDs
• SCSI Cabling—Verify that all SCSI cables are securely connected at both ends. Check the
length and integrity of your SCSI cabling. The total length of all cables connected to a SCSI
bus must not exceed 19 feet (6 meters) for a SCSI-1 SE bus, 10 feet (3 meters) for a Fast
SCSI (Narrow or Wide) or an Ultra SCSI (Narrow or Wide) SE bus, 40 feet (12 meters) for
an LVD bus with multiple devices, or 82 feet (25 meters) for an LVD bus with a single
device. The length of the internal SCSI cabling inside the autoloader is 2 feet (60 cm). This
length must be included in any calculations of cable length.
• Termination—If the autoloader is the only SCSI device—other than the SCSI host system
adapter—on the selected SCSI bus, it must be terminated. Likewise, if the autoloader is
physically the last SCSI device on the SCSI bus, it must be terminated. Only the devices
physically 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. To terminate the autoloader, locate the terminator
in the accessories package and press it firmly into either of the two SCSI connectors on the
rear panel of the autoloader. Secure the terminator by tightening the finger-screws until
snug. The supplied terminator is "dual mode" and will work on both Low-Voltage Differential
(LVD) and Single Ended (SE) SCSI buses. Check all SCSI and power connections and
confirm that the unit is attached to a valid SCSI SE or LVD bus.
