Is both the control path and data path down? Do an mping from the two wlcs, if the mping fails then UDP 16666 & 16667 (if using secure mobility) are blocked. If eping fails between the two, then IP 97 is blocked. These are all you need to configure mobility between a FW. Make sure the mac address, IP address and mobility group name are correct on the mobility group configuration.
Looks like you configuration of your mobility group is wrong.... WiSM (10/15) is not going through a FW and the mobiliity is not up. Make sure you either have Symetric tunneling enabled on all or disabled. Can you post your show run-config?
