2. Connect the other ends of the SCSI cables to the SCSI bus. Ensure that the bus is
correctly terminated.
9-4
If the tape drive will terminate the SCSI bus, install an active Ultra 160
SCSI terminator on the unused SCSI connector.
Connect an external SCSI cable to a tape drive.
The LTO4 SCSI tape drives provide active termination.
Route an external SCSI cable through the appropriate slot on the back of the
system controller.
Attach the cable to a port on a SCSI HBA. If multiple SCSI and Fibre
Channel HBAs are installed the SCSI HBAs must be installed in the left
slot(s) first, next to the CAN bus controller card, then followed by any Fibre
Channel HBAs.
Be sure to connect the cable to the HBA port you
specified when creating the logical library (see
page 12-8).
