a connected TotalStorage DS400. One for one port of controller A and one
for one port of controller B. The port name can be used to identify the
TotalStorage DS400. The last 8 digits of the port name are identifying the
TotalStorage DS400 across both controllers and ports. The third and
fourth digit identifies the port to which the HBA has a connect. The screen

only show the target devices but no LUNs.
