Exabyte 1X7 LTO manual 104, Including bus hangs and Read/Write failures

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.

! 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.

✔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.
