WLC 7.5 5508 High Availability - Can't find peer

I am trying to configure high availability for two wireless lan controllers 5508 following this documentation,

http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bd3504.shtml

The problem is the controllers will not find or recognize each other.  At bootup it says no peer found.

I have checked the software versions are both on 7.5.102.0.

They can ping each other's management ips.  The redundancy mgmt ip and peer redundancy mgmt ip are correct.

They are connected with an ethernet cable on the redundancy ports.

I cannot ping it's own or peer's redundancy port ip (example. 169.254.0.51 )

SSO is enabled and primary on one controller.

The other is secondary and when enabling SSO it reboots, can't find peer and goes to maintenance mode.

The secondary has no config besides the mgmt ip settings.  The primary should copy it's config over after redundancy is set.

How can I get the controllers to recognize each other?  Am I missing some config?

Please refer to the link for High-Availability configuration of the WLC.

What are you referring to?

It's the same instructions, the deployment guide is the same,

Are both the "Redundancy Mgmt IP" & "Peer Redundancy Mgmt IP" in the same VLAN and subnet?

What about the "Service Port Peer IP"?

The are in the same vlan and subnet.

The problem ended up being the etherchannel.  For some reason it would do peering when all 4 connections were up, so I unplugged 3 out of the LAG then it did peering correctly and I re-plugged them after.
