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, as well as for Ultrium 230.
