Do Not:

• Attach the tape drives to a non-LVD SCSI controller, as this will
degrade the performance of the tape drive and the performance of
your backups.
• Attach non-LVD SCSI devices on the same bus cable, as this will
degrade the performance of the tape drive and your backups.
• Connect the tape drive to a disk RAID controller, as this is not sup-
ported.
If you are installing an adapter, we recommend you use a SCSI LVD
controller kit that includes the SCSI cable and terminator.
If installing a SCSI HBA, be sure it is supported by your operating system
and your backup software application. In addition, ensure that you have
the proper drivers for the HBA, if any are necessary.
Before you install the HBA, check and record your current system
configuration. For example, in Windows 2000, you may find information
on any currently installed SCSI HBA by:
• Double-clicking on
Administrative Tools
in the Control Panel.
• Clicking on
Computer Management > Device Manager
.
• Clicking on the SCSI host adapters listed.
• Clicking on
Properties
to view the Resources tab.
In UNIX/Linux systems, you may find information on any currently
installed SCSI HBA by viewing the boot log text file. Refer to your
operating system documentation for specific information on reviewing
your system configuration.
After installing the SCSI HBA, reboot the system. Then ensure that the
operating system recognizes the HBA and that there are no conflicts with
other adapters.
Adding the Tape
Drive

We recommend that the LTO-3 Tape Drive be attached to a dedicated
SCSI HBA. In addition to enabling the best performance for your tape
drive, a dedicated SCSI HBA reduces the chances of installation
difficulties arising from duplicate SCSI IDs on the same bus channel.
