Troubleshooting Installation Problems

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 and two Logical Unit Numbers (LUNs): one LUN for the tape drive (0) and one for the autoloader robotics (1). 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 before you can use the autoloader. Select an unused SCSI ID. See the manuals for the other devices on the SCSI bus or your operating system to determine which SCSI IDs are currently in use. If the autoloader is attached to a narrow (50-pin) SCSI bus, only SCSI IDs 0 through 7 are available. See Changing the SCSI ID on page 41 for instructions.

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 6 meters (19 feet) for a SCSI-1 SE bus, 3 meters (10 feet) for a Fast SCSI (Narrow or Wide) or an Ultra SCSI (Narrow or Wide) SE bus, 12 meters (40 feet) for an LVD bus with multiple devices, or 25 meters (82 feet) for an LVD bus with a single device. The length of the internal SCSI cabling inside the autoloader is 30 cm (1 ft). This length must be included in any calculations of cable length. Try replacing suspect cables with known good cables.

Termination:

If the autoloader is the only SCSI device - other than the SCSI host 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.
