which method to enable disable server?

Look at the LocalLB::PoolMember::set_session_enabled_state() method.

 struct IPPortDefinition {  
    String address;  
    Long port;  
  };  
    
  enum EnabledState {  
    STATE_DISABLED = 0, // The object is disabled.    
    STATE_ENABLED = 1   // The object is enabled.    
  };  
    
  struct MemberSessionState {  
    IPPortDefinition member  
    EnabledState session_state  
  };  
    
  void LocalLB::PoolMember::set_session_enabled_state(  
    in String[] pool_names,  
    in MemberSessionState[][] session_states  
  );

You call this with an array of pools that you want to manipulate in the pool_names variable and then pass the members for each of the pools you want to change in the session_states variable.

If you want to disable all access to a given Node, you can can also set the session state at a global address level using the LocalLB::NodeAddress::set_session_enable_state() method

void LocalLB::NodeAddress::set_session_enabled_state(  
    in String[] node_addresses,  
    in EnabledState[] states  
  );
