Chapter 7. Troubleshooting

Compatibility
Ensure that the library is compatible with the HBA and backup application you plan to
use. For a list of compatible SCSI adapters, check with your HBA manufacturer. For a
list of compatible software applications, check Spectra Logic’s web site.
Note:
The host bus adapter for the library should be SCSI-3 LVD.
A single-ended SCSI host bus adapter will severely degrade
performance. Also, if there are any SE devices on the same SCSI
bus, the entire SCSI bus will negotiate down to SE speed and
severely degrade performance.
HBA Installation
Verify that your HBA is installed correctly. Refer to the manual that came with the HBA
for installation and troubleshooting instructions. Pay particular attention to any steps
describing the settings of various jumpers and/or switches, if applicable. Make sure
that the HBA is properly seated in the motherboard slot and the operating system
correctly detects the HBA. Make sure that the proper device driver is installed.
Backup Application Installation
Refer to the documentation included with your backup application for instructions on
how to verify proper installation. Some backup software packages require an
additional module to communicate with the library robotics.
Device Driver Installation
Many backup applications use their own drivers in
conjunction with the library and drive. Before installing a driver, make sure it will not
conflict with the software.
