Enter the following command:

lsdev–Cs scsi.

This shows all the SCSI

target IDs known to the system. Note the SCSI target IDs and choose a

SCSI ID for the LTO-3 Tape Drive that will not conflict with the IDs

shown from the lsdev command.
SCSI ID #7 is almost always dedicated to the SCSI controller. Never

configure your target device for ID 7 unless you are absolutely sure that

the controller is not addressed for ID 7.
