Installation Best Practices

In addition, 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 supported.

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 We recommend that the LTO-2 Half-Height Tape Drive be attached to a

Drivededicated 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.
