Note: After changing the mode type of one port, the other port also gets changed. aff::> system node hardware unified-connect modify -node aff-01 -adapter 0c -mode cna -type target -force true.Any changes will take effect after rebooting the system. Therefore, it is not possible to configure one port in a UTA2 port pair as FC target/initiator and the other port in the CNA (FCoE target/Ethernet) mode.
