Configure 5500s w/ LAG and HA

Question

Working on a pre-deployment setup for a pair of 5508's that are to be used in HA.  Network information should be as follows:
WLC_1: 192.168.100.200 (HA primary)
  Redundancy Managent 192.168.100.202
WLC_2: 192.168.100.201 (HA secondary)
  Redundancy Managent 192.168.100.203
These are both connected to a 3750X w/ the following port layout
WLC_1 Port 1 --> Gi 1/0/1  
      Port 2 --> Gi 1/0/2
      RP --> Gi 1/0/5
WLC_2 Port 1 --> Gi 1/0/11 
      Port 2 --> Gi 1/0/12
      RP --> Gi 1/0/6
I've gone through the wizard choosing NO for LAG and for HA, with the expectation that I would do this after(I also tried it choosing both in the wizard, and then one or the other).  When doing so, I'm able to get to both the primary and secondary (both ports temporarily connected to non-lag ports on the switch) from a machine on the same lan (there is currently no gateway as this is on my desk for setup).  
When I issue a "config lag enable", save the config, reboot the controller and move the cables to the correct ports on the switch I'm unable to get any communication to the controller.  Below is what I have for the interface config on the controller:
config interface address management 192.168.100.200 255.255.254.0 192.168.100.20 
config interface dhcp management primary 192.168.100.20
The switch config is as follows:
interface Port-channel1
switchport trunk encapsulation dot1q
switchport trunk native vlan 100
switchport mode trunk
interface GigabitEthernet1/0/1
switchport trunk encapsulation dot1q
switchport trunk native vlan 100
switchport mode trunk
channel-group 1 mode on
interface GigabitEthernet1/0/2
switchport trunk encapsulation dot1q
switchport trunk native vlan 100
switchport mode trunk
channel-group 1 mode on
I've used this in the past on 2504's and 4400's so not sure if i missed a 5500 specific item.  I didn't disable any ports and verified that all ports are enabled on the controller.  So I reverted the changes and tried to enable HA using the following config:
WLC_1
config redundany unit primary
config interfac address redundancy-management 192.168.100.202 peer-redundancy-management 192.168.100.203
config redundancy mode sso 
WLC_2 
config redundancy unit secondary
config interface address redundancy-management 192.168.100.203 peer-redundancy-management 192.168.100.202
config redundancy mode sso
After the reboot I'm unable to ping either controller using the management address.  The controllers can ping each other on their 169.254.x.x address, but I'm unable to access them from the LAN.

Hi Scott,
Yes I did.. But it seems that after deselecting the "Interface/Interface Group(G)" under the SSID´s and then selecting the dynamic interface again that the problem is resolved.
