Problems with Library Installation
If your library and application software are not communicating after installation and configuration, check
the following:
• SCSI IDs. Make sure that the SCSI IDs you selected for the tape drive and library are not
the same as the ID used by any other SCSI device on that bus, including the SCSI adapter
card. Refer to the Configuration chapter for information about setting the SCSI IDs.
• SCSI Bus Connections. Make sure that you have connected the SCSI cables to the
appropriate SCSI connectors on the back of the library. See the Configuration chapter and
Appendix B for more information.
• SCSI Cabling. Make sure that all SCSI cables are securely connected at both ends.
• LVD, HVD, and Single-ended SCSI Devices. Because the library is an LVD device, all
other devices on the SCSI bus must be LVD.
• Narrow SCSI and Wide SCSI. Because the library is a wide SCSI device, all other devices
on the bus must be wide.
• SCSI Cable Lengths. Make sure the internal SCSI cabling does not exceed maximum
lengths (see Appendix B).
• Termination. Make sure your bus is properly terminated as described in Appendix B. If
another SCSI device previously terminated the SCSI bus and is no longer at the physical
end of the bus, be sure to remove the terminators from that device.
• Compatibility. Make sure that your tape drive and library are compatible with the SCSI
adapter card and application software you plan to use. Visit Plasmon’s web site at
www.plasmon.com for compatibility information.
• SCSI Adapter Card Installation. Make sure that you installed your SCSI adapter card
correctly. Refer to the documentation that came with your card for installation and
troubleshooting instructions. Pay special attention to steps describing setting various
jumpers and switches on the card. Make sure that the card is properly seated.
• Software Installation. Make sure that your application software is installed correctly. Refer
to the documentation that came with your software. Pay special attention to steps
describing configuring the software for use with the library and tape drive.
• Control Mode. Make certain the control mode is set to SCSI or Sequential. See the Library
Operation chapter for more information.
After checking these items, reset the library as described in the Library Operation chapter.
