Availability overview

Events and actions during a failover
If one of the HiPath Wireless Controllers in a pair fails, the connection between the two HiPath
Wireless Controllers is lost. This triggers a failover mode condition, and a critical message
appears in the information log of the remaining HiPath Wireless Controller.
After the wireless AP on the failed HiPath Wireless Controller loses its connection, it will attempt
a reboot, unless the
Link Persistence
option is enabled. (If the AP is unsuccessful after five
minutes of attempting to register with the controller, the AP does not reboot, and instead waits
five minutes before attempting to reboot and register again.)
If the AP is assigned to different VNSs on the two controllers, it will reboot. Because of the
pairing of the two HiPath Wireless Controllers, the wireless AP will then register with the other
HiPath Wireless Controller.
All user sessions using the AP that fails over will terminate unless the
Maintain client
sessions in event of poll failure
option is enabled on the AP Properties tab or AP Default
Settings screen.
