We have 2 Aruba 7010 acting as master and local and have configured HA between using the loopback IP addresses.
When I issue the command show switches all looks good :
(WLC01) #show switches
All Switches
------------
IP Address Name Location Type Model Version Status Configuration State Config Sync Time (sec) Config ID

10.0.0.101 WLC02 Building1.floor1 local Aruba7010 6.5.0.3_57242 up UPDATE SUCCESSFUL 1 12
Total Switches:2
On the AP database it seems that the AP knows the backup :
(WLC01) #show ap database

-When I test the HA by taking the cables out from master the AP stays INnactive :
(WLC02) #show ap database
