LICENSE as status in High Availability

Question

We have a cluster with two Sophos SG 230. In High Availability -> Status, the second firewall status is "LICENSE" 
 The first firewall is now Master and the status is "ACTIVE" as it should be. 
 I checked Licensing menu and everything seems ok. 
 
 I could find any explanation of LICENSE status in the manual. Could you help me to understand what does it mean? 
 
 Thanks in advance

If you are running in Active/Standby mode for HA (only one unit at a time processes traffic, and fails over if a unit hangs up / dies etc.) no additional license is required; I suspect you have setup your HA in Acive/Active (both nodes actively processing traffic) mode, which does require a special license to run. If you intended to only run in Active/Standby (or Active/Passive, can't remember how its displayed at the moment) then you will need to break your HA and set it back up again. If you want Active/Active, you will have to convert your license (in the MyUTM portal) into a Cluster-capable license; this typically halves the time remaining on the subscription (or more, if it's more than 2 nodes) -- so know that going in. Contact your Reseller for help; they should be experienced with this feature. The way it's typically sold, if a customer asks me (we're a Platinum Solutions Provider) for Active/Active, is we sell double the term needed then convert the license for them.
