From the Aruba 7205 controller installation guide here: https://support.arubanetworks.com/Documentation/tabid/77/DMXModule/512/Command/Core_Download/Default.aspx?EntryId=17286
"10GBASE-X Ports The 7205 controller is equipped with two 10GBASE-X (SFP+) ports (4 and 5). These ports are intended for use with SFP/SFP+ and support dual-speed (1GbE or 10GbE) operation."
In other words, you cannot configure the duplex on them.
