c. Select the virtual tape drive to edit (the one for which you deleted the connection) and
click Edit. The Edit Virtual Tape page is displayed:
d. From the bus drop-down list, select the bus ID to which the host you are currently
configuring is connected. To determine the bus ID, you must find the PCI slot number
on the back of the VTS server module where the SCSI or Fibre Channel cable connects
from the card to the target. Labels indicate the bus number for each port.
e. From the target drop-down list, select the SCSI ID on which the virtual tape will
respond. This is the ID that the host uses to identify its target, and the ID typically
ranges from 0–15.
Note Fibre Channel devices use LUN-based addressing. SCSI devices use target-
based addressing. For Fibre Channel devices, the LUN determines the unique
address of the device on the bus. When assigning the target ID and LUN, be
sure to assign a unique combination. For example, you cannot assign target
ID 0 LUN 0 and target ID 1 LUN 0 on the same bus; this creates a conflict. All
target IDs on a bus must be identical, and you cannot assign a LUN value
more than once per bus.
