The physical ports of the interface modules in quadrants A, B, C, and D belong to controllers A, B, C, and D respectively. The ownerships cannot be modified.
Figure1 Owning controllers of physical ports

On an iSCSI network, the physical and logical ports of the Ethernet interface modules have the same owning controllers. That is, the logical ports created on the interface modules in quadrants A, B, C, and D belong to controllers A, B, C, and D respectively. The ownerships cannot be modified.
Figure1 Owning controllers of logical ports

But the owning controllers of logical ports created on ethernet interface modules on a NAS network and the owning controllers of logical ports created on RoCE interface modules will have a different relationship, you can refer to https://forum.huawei.com/enterprise/en/owning-controllers-of-logical-ports-created-on-roce-interface-modules/thread/689859-891 and https://forum.huawei.com/enterprise/en/owning-controllers-of-logical-ports-created-on-ethernet-interface-modules-on-a-nas-network/thread/689845-891 to get the detail information.
