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.
