(AIX Version 4.1.x and later)
Finding Existing SCSI Controllers and Devices
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-1 and LTO-2 drives 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.
