          Hi Adam,

          In order to set up connected mode, please try first disabling IPoIB enhanced mode to do so please follow the procedure below:

          1) Disable "ipoib_enhanced":

          #vi /etc/modprobe.d/ib_ipoib.conf


          Add the following entry:

          options ib_ipoib ipoib_enhanced=0


          2) Stop and start openibd service:

          #/etc/init.d/openibd stop

          #/etc/init.d/openibd start


          3) Verify parameter is disabled: (The value should be 0)

          #cat /sys/module/ib_ipoib/parameters/ipoib_enhanced


          4) Verify the mode:

          #cat /sys/class/net/ib0/mode


          Once disabled please go ahead and enable connected mode.
