Answer

To change the number of available logical ports from default of 4 to a higher or lower number, here is the procedure:

1) First step is to access the managed machine on the HMC following the below screenshot:

2) set the number to the correct value:
1= 16 ports available for use.
2= 8 ports available for use.
4= 4 ports available for use.

Last step is to shut down the whole frame (power down the whole frame)
then power the frame back on and you will have the new amount of ports available for use.
