CHAPTER 8—TROUBLESHOOTING
✔ LVD SCSI devices. Because the autoloader is an LVD (low-voltage
differential) device, all other devices on the SCSI bus should also be LVD.
These devices include the controller cards, terminators, and any other
devices on the bus. Do not mix LVD and HVD devices on the same bus.
Note: Although Ultra-2 and Ultra-3 LVD SCSI are compatible with
single-ended SCSI, Exabyte does not support the use of an LVD
autoloader on a single-ended SCSI bus.
✔ SCSI cable lengths. Make sure that the cabling for the SCSI bus attached to
the autoloader does not exceed the maximum length restriction (see page 16).
✔ Termination. Make sure that the SCSI bus is properly terminated (see
page 15). If another device previously terminated the SCSI bus and is no
longer at the physical end of the bus, be sure to remove the terminator from
that device.
✔ Compatibility. Make sure that your autoloader and tape drive are
compatible with the backup software you plan to use. Check
www.exabyte.com/support/online/documentation/compatibility.cfm for
compatibility information.
✔ Software installation. Make sure that your application software is installed
correctly. (Refer to your software documentation.) Pay special attention to
steps that describe how to configure the software for use with the autoloader
and tape drive.
✔ Driver installation. Refer to the installation instructions for your backup
application regarding medium changer and tape drive drivers.
Make sure that the driver for your controller card is installed. Refer to the
installation instructions for the controller card.
Make sure that the appropriate drivers for the Magnum 1x7 LTO
Autoloader and LTO tape drive are installed.
Notes: Driver installation may not be necessary and depends on the backup
application that you use in your system. Refer to the installation
instructions for your backup application for verification.
LTO drivers for Windows native backup application are available as a
free download from
www.exabyte.com/support/online/documentation/compatibility.cfm.

! Important
Both LTO-2 and LTO-3 SCSI tape drives require an Ultra 3 or
LVD 160 terminator to function properly on the SCSI bus. An
inadequate terminator will result in various SCSI bus issues,
including bus hangs and Read/Write failures.
