D Configuration Examples
This appendix illustrates potential SCSI cabling configurations.

NOTE: For step-by-step instructions on how to install and configure the library, see
SCSI Configurations" on page 36.

SCSI Cable Configurations

Use the following guidelines when configuring your SCSI cables:
• Use the highest quality SCSI cables.
NOTE: Bus errors caused by excessive length or poor quality cables can significantly degrade
performance and reliability.
• Each of the tape drives in the library, and the library controller constitute a separate SCSI target.
When any two or more devices are connected to the same SCSI bus, each separate SCSI device
must be assigned a unique SCSI ID.
• SCSI IDs are set at the factory. Use the GUI touch screen to change any of the factory defaults.
• To connect a library to a host, the host must have at least one Wide LVD controller and the
appropriate driver software.
NOTE: The Single-Ended SCSI interface has a lower performance than LVD SCSI, and also has
shorter cable requirements.
• For optimal performance, do not attach more than two drives per SCSI bus.
NOTE: One drive per bus is HP's recommended configuration. Two drives per bus is an
acceptable configuration for SDLT 1 and 2.
