Controllerless Networks

Dear expert,
i have 2 MM controller 
2 controller configure as acluster(hq) 
and i have 3 another controller in another 3 branch
i configure in controller in 3 branches if controller get down all access point get to cluster(hq) 
and when return to wright contrller (apboot) some access point stuck in hq cluster and return only after rest access point or 2 provision access point to another controller and return to right controller so how can solve if on of three controller get down and access poit stuck in hq

If an access point fails over to a new cluster, the access point forgets that previous cluster and only has knowledge of the ip addresses of the controllers in that new cluster.  That is why it is not good to fail over to a new cluster, if you expect the access points to ever fail back.  A cluster is its own redundancy and access points failing to a new cluster is considered a "last resort".

EDIT:  If you want all of those access points in HQ to go back to the previous cluster, put an LMS-IP in the AP-group to point to one of the controllers in the first cluster.

when show booting sequence to access point i see two ip for 2 controller in cluster so any opinio to solve this isuue

There is no solution.  You should not fail over to a second cluster, because your access points will not come back.

solution is bridge if controller become a down all access point in this controller go to cluster but some access point stuck and not return to original controller

You should have someone review your design and let you know what your options are.
