    You can achieve this by using priority group.

    Local Traffic  ››  Pools : Pool List  ››  pool_name

    Priority Group Activation   Less than  1  Available Member(s)

    for server A you need to use higher priority

    Hi Mate,

     

    You can configure priority in the pools for the specefic nodes which will ineffect and Active/Stand by state.

     

    Navigate to Local Traffic ›› Pools ›› Pool List and click on the specefic pool name. Go to members and click on each member name.

     

    in the configuration section configure the Priority group 10 for active and continue with another node with priority 5 for passive.

     

    Now you can see all the traffic is sending to node 1 and once node 1 goes down traffic will send to node 2.

     

    Hope this helps.

    Yes - once the higher priority group meets the 'minimum active members' threshold it will take all new connection requests (since you noted no persistence). However note that any ACTIVE connections that are on Node2 when Node1 comes back online will remain on Node2.

    Does Round Robin {LB Method} works with Active (high priority), Passive Priority settings?
