Jon, under normal circumstances there should not be any change in the VC. If the VC is lost, like during a reboot, another AP will take the AP role and the other APs will take that VC. From your description, that is what is happening.
Check this section in the user guide, which is for version 8.3 but the concept has not really changed, to learn how the VC election is done.
I would check the logs for the AP that was the VC and find out why it was lost. Your Aruba partner or Aruba TAC support can assist in this as well.

Subject: Virtual controller changes randomly
Every few days, I get a list of alerts from AirWave that concern a specific IAP that appears to have become the new VC for the cluster - all the alerts look like the other IAPs in the cluster registering with the new VC. I'm unable to determine what triggers this change in the virtual controller from one AP to another. Is there a way to determine the cause from the information contained in the alert messages? So far i haven't been able to figure anything out from that.
This seems to happen with a fair amount of regularity - only to two of our clusters, though - the one at the high school and the one at the middle school. The two elementary schools never show this behavior.
Appreciate any insight.
Thanks.
