I am newer to working with aruba, and need to clarrify some things as I'm troubleshooting some connection and HA/failover issues.
My scenario: we have two 7240's, one is a master and one is a local. Both controller configs show this for the HA settings...
ha group-profile "HA-Group-Prof"
preemption
state-sync
pre-shared-key xxxxxxxxxxxxxxxxxxxx
heartbeat
controller xxx.xxx.xxx.xx1 role dual
controller xxx.xxx.xxx.xx2 role dual
1. Since both are set as dual, is this considered "active/active"??
2. On our main AP system profile, both the "LMS IP" and the "BACKUP LMS IP" are set. (LMS IP = xxx.xxx.xxx.xx1, BACKUP LMS IP = xxx.xxx.xxx.xx2). The "LMS Preemption" box is checked, and hold down is set at 600 seconds. Is this misconfigured? If both controllers are set for dual, should a BackupLMS IP be specified?
3. I dont think we have VRRP set up. "Show ap tech-support" for one of my WAPs shows this for the controller section...

VRRP No
4. Reference the attached diagram that describes my setup to help with the next question. All WAPs were terminating to MC1, and they had their backup tunnel established to MC2. I downed port e7/11 on 7K#1 (which is uplink to MC2). As soon as I did this, all of the WAPs left M1 and reterminated over on M2. (this made no sense to me) WAP logs showed this the second after I downed the link...
2018-09-27 07:14:42 Failover request from standby: fail-over to xxx.xxx.xxx.xx2
Does this mean the standby controller (M2) lost its "standby tunnel" and was trying to reestablish it?
