In order to use a WLC that has a license as an HA WLC, you need a minimum of a 50 AP license.

http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bd3504.shtml

If you want to convert any existing WLC as a Standby WLC, do so using the config redundancy unit secondary command in the CLI. This CLI command will only work if the WLC which is intended to work as Standby has some number of permanent license count. This condition is only valid for the 5500 WLC, where a minimum of 50 AP Permanent licenses are needed to be converted to Standby. There is no restriction for other WLCs such as the WiSM2, 7500, and 8500.
