Check that the "nsshow" command can show various information on fibre channel
devices linked up to FC Switch Modules.
If the information on a connected device does not appear, the device, SFP module or FC cable may be defected.
For details of the displayed information, refer to the User’s Guides of the connected fibre channel devices.

Depending on the type of the OS you use, "PID" has some influence on the hardware
path of the logic with which the OS recognizes disk array units. Take sufficient note on the PID if a job is done to change the PID after system operation is started.
